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 role of the Drilling Fluid Circulation System Supporting the drilling rig

The Drilling Fluid Circulation System can strengthen the solid phase control of the drilling fluid; through the rational use of solids control equipment such as shale shakers, de-sanders, desilters, cyclones and drilling fluid cleaners, it can reduce the dilution of drilling fluids and the amount of treatment agents.The closed drilling fluid circulation system can prevent the drilling fluid from landing and avoid leakage pollution.

The Drilling Fluid Circulation System for the drilling rig includes drilling pumps, surface manifolds, mud tanks, mud purification equipment, etc. The surface manifolds include high-pressure manifolds, risers, and hoses, and the mud circulation system equipment includes drilling fluid shakers and desanders, desilter, centrifuge, etc.

The drilling pump sucks the mud from the mud tank. The mud pressurized by the drilling pump passes through the high-pressure manifold, riser, and hose, enters the tap, goes down to the bottom of the well through the hollow drilling tool, and ejects from the water hole of the drill. The cuttings are carried back to the ground through the circular space between the wellbore and the drilling tool, and the mud returned from the bottom of the well is passed through various levels of mud purification equipment to remove the solid content, and then reused.

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.
