The “blood” filter of drilling – Solids Control System

The mud solids control system is one of the most important parts of the whole drilling rig system, which is called the “blood” filter of drilling. A reasonable solids control system can effectively control the solids content of the drilling fluid and reduce the complexity of the drilling process and the probability of accidents. It is an important technical means to achieve safe, efficient and economical drilling.

Understand the performance and main characteristics of the solids control system, and select reasonable solids control equipment that meets the requirements according to the characteristics of the formation cuttings particles, the properties of the drilling fluid and other factors, so as to reduce the risk of accidents during the drilling construction process and improve the safety of drilling Drilling speed.

The solids control system is composed of shale shaker, desander, desilter, drilling fluid cleaner, centrifuge, drilling fluid tank and other equipment. Once a certain equipment fails or the overall matching is inappropriate, it will directly affect the performance of the entire drilling rig. Increase the risk of accidents during drilling construction. Therefore, the performance of the solids control system has important practical significance for drilling engineering.

Treatment effect of five-level drilling fluid solids control system equipment

The drilling fluid solids control system is mainly used to remove harmful solid phases such as drill cuttings and recover useful solid phases such as barite. The solids control system is mainly composed of mud tanks, drilling fluid shale shakers, desanders, desilters, drilling fluid centrifuges and other major equipment, as well as auxiliary equipment such as mud pumps, slurry mixing devices, and vacuum degassers.

The mud tank is mainly used to store the mud and is the carrier of the solids control equipment. The mud purified by the solids control equipment enters the various chambers of the mud tank, and is processed according to different equipment, so as to achieve the removal of solid particles, recovery of barite, and purification of the mud.

The general processing flow of the solids control system: The drilling fluid shale shaker is the first-stage treatment equipment in the solids control system, which can remove the larger solid phase in the drilling fluid, and can remove solid particles above 74μm. The vacuum deaerator is used to remove the gas in the mud. It is the second and solid control device in the solids control system. It can quickly and effectively remove the gas contained in the mud. The deaerator is useful for restoring the mud density and preventing potential blowouts. It plays an important role in the occurrence of the danger of well collapse. The solids control equipment ranked at the third level is the drilling fluid desander. The mud treated by the vacuum degasser is transported into the desander through the sand pump. The drilling fluid desilter is used after the desander, which is used to remove the solid phase of 15~44μm to further ensure the performance of the drilling fluid.

In some solids control systems that need to save space, a desander, a desilter, and an underflow screen can be combined to form a drilling fluid cleaner, which can effectively remove solid particles larger than 15μm. In some uncomplicated drilling platforms, it can completely replace the desander and desilter. The final treatment equipment of the solids control system is a drilling fluid centrifuge, which is mainly used to remove solid particles smaller than 7μm and recover barite, with a recovery rate of 95-97%.

The solids control equipment is mainly used for complex well conditions and demanding well conditions. In the actual application process, according to the needs of drilling operations, one of the mud solids control processes can be used in one or more stages.

The function of solids control system in the process of oil drilling

The solids control system in the oil drilling process mainly realizes the control and separation of the solid phase and the liquid phase of the drilling fluid, and recycles the drilling fluid, also known as the mud purification system. The solids control system is composed of several modular combined tanks to avoid mud settling at the bottom of the mud tank. A stirring device is designed on the mud tank. The tanks of the entire circulation system are independent and connected to each other to form a certain technological process meets the requirements of mud purification and meets the technical requirements of oil drilling construction.

Design multiple purification equipment in the solids control system. The supporting equipment contains shale shaker, mud agitator and desilter, etc., to reduce the discharge of waste cement slurry, avoid environmental pollution accidents, improve the safety and environmental protection of oil drilling construction, and achieve green drilling Construction needs.

For oil drilling operations, vertical wells are the simplest drilling task. However, directional wells and horizontal wells are difficult to drill and are complex drilling operations. The solids control system for drilling construction is to meet the technical requirements of drilling fluid solids control. Through the solids control equipment, the solid content in the drilling fluid is reasonably controlled, and the purification of the drilling fluid is strengthened to make its performance meet the technical requirements of complex drilling construction. Reduce the cost of drilling construction as much as possible, improve the quality of oil drilling construction, and meet the needs of oil and gas field exploration and development.

Precautions for operation of mud solids control equipment system

For the operation of the mud solids control system, the mud solids control equipment must be thoroughly and carefully inspected before drilling. Among them, great attention should be paid to the equipment of the drilling fluid shale shaker. The specifications of the screen should be as complete as possible, and multi-standard sieves should be used. The net can reduce the burden of the subsequent solid control equipment and improve the efficiency of solid control.

At the same time, pay attention to all kinds of manifolds. The gate and the main body of the mud solids control equipment must be disassembled for inspection and maintenance. The sand pump is all unloaded until the blades are exposed. Reinstallation and pressure test can be performed after confirming that there is no blockage or damage in each link to ensure that the solids control equipment is at its best In good condition; all kinds of reagents, balances, supply tanks and other corresponding equipments and instruments for mud testing and analysis should be available. After drilling, the solids control equipment must be operated continuously regardless of whether it is drilled or not to ensure that harmful solid phases are removed to the greatest extent. The solid content of the mud does not change during the drilling process, and the performance of the mud will not deteriorate without chemical pollution. The low solid content is beneficial to protecting oil and gas reservoirs, increasing the ROP, reducing mud costs and even drilling costs.

After the completion of the well, all the mud solids control equipment shall be completely disassembled and cleaned, and the key parts shall be coated with oil for protection; each solids control equipment shall be sealed up after installation of spray paint.

Solids control is a technique used in a drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally, a solid control system contains five stages: the mud tank, oilfield shale shaker, vacuum degasser, desander, desilter, and centrifuge. The shale shaker is used to separate big solids with diameter above 75μm, the desander treats solids from 45–74μm, and the desilter segregates solids between 15–44μm. Sometimes the desander and desilter are combined as one highly efficient mud cleaner. When air enters the drilling fluids, a vacuum degasser is used to separate the air. If no air is found in the mud, the degasser will work as a big agitator. All these stages are mounted on the top of the mud tank. After separating the solids, the clean mud can be pumped into the borehole again.

The drilling mud system will separate unuseful drilling cuttings and other solids among drilling fluids. It will correct drilling mud property and keep the drilling fluids performance good. Solid control effect to well drilling also includes holding proper gravity, density, weight, etc. Good solids control to well drilling will produce good quality drilling fluids during whole well drilling. The good drilling fluids will influence good drilling greatly. Use good drilling fluids, the well drilling will be fast and efficient, the drilling cost will be less than those bad solids control well drilling. During whole drilling mud system, we’ll get good and safe drilling condition decrease and even prevent blowout danger. So nowadays we take solids control as rather essential part for oil and gas well drilling, geothermal well drilling, CSM exploration, etc.

Working principle of cyclone desander

Origin of cyclone desander:

Sand removal equipment is often eroded, resulting in solid particle deposition and pipe blockage. In order to solve this problem, a solid-phase/liquid-phase swirling desander device has been developed for separating and eliminating solid particles in well fluids. Compared with the traditional filter desander, kexun swirl desander has the characteristics of compact structure and high working efficiency.

Working principle of cyclone desander:

The basic principle of the cyclone desander is to use centrifugal force to introduce the fluid tangential direction into the conical shell of the cyclone desander. The gravity action pushes the solid particles to the surface of the cone and runs down to the outlet of the separator. The secondary liquid swirl generated in the separation shell causes the liquid to migrate upward and discharge from the overflow port through the swirl detector. The smaller the diameter of the desander cyclone is, the greater the separation effect will be.

Features of KOSUN cyclone desander:

  1. Simple structure, easy operation, safe and reliable use, almost no maintenance;
  2. Compared with the expanded pipe, buffer box and other sand removal equipment, it has the advantages of small volume, large processing capacity and saving field space;
  3. Sand can be removed from the water during the continuous water supply;
  4. It avoids the phenomenon of secondary pollution of water quality in other ways of sand removal and has high efficiency of sand removal.

It is recognized at home and abroad that mud solid control equipment is one of the important symbols of scientific drilling.

It is recognized at home and abroad that mud solid control equipment is one of the important symbols of scientific drilling. Through the continuous improvement and improvement of drilling fluid solid-phase control equipment in recent 10 years, it has a significant effect on improving drilling technology, reducing the maintenance workload of circulation system, ensuring the performance of drilling fluid, reducing downhole accidents, increasing drilling speed and reducing cost.

Prior to the 1970s, the petroleum drilling industry used extremely crude drilling fluid shale shaker, with a separation size of only 400 microns and solid particles re-entering the mud circulation system.Later, ultra-fine vibrating screen, cyclone desander, mud desander, drilling fluid centrifuge, vacuum degasser, mud mixer, slurry distribution device, mud tank and electrical operation cabinet, with the total weight of more than ton, the total power consumption has been close to 300KW.Solid content can be controlled to a minimum of less than 5%, and the low-density properties of the drilling fluid can be adjusted as needed.

There is no doubt that these advances have brought about profound changes in the oil drilling industry. But at the same time also greatly increased the well team site repair, maintenance, use of the workload and consumption.Therefore, on the basis of constantly reducing the performance of the mud solid control system, it has become a very concerned issue for experts of mud solid control equipment at home and abroad to simplify the equipment, reduce energy consumption and improve reliability.

The solid control system for oil and gas drilling
