Application of Solid Control Technology in Oil Drilling, HDD Crossing, and Geothermal Drilling Engineering

Solids control is a technique used on a drilling rig to separate the solids produced by crushed drill bits and other debris from drilling fluids or mud. Solid control equipment can be used in oil exploitation, horizontal directional crossing engineering, geothermal drilling engineering, and so on. The performance and quality of drilling fluid solid control equipment is the key to solid control technology. The drilling fluid solid control system mainly includes three parts: a drilling fluid circulation tank, drilling fluid purification equipment, and electrical control equipment. Among them, drilling fluid purification equipment mainly includes a shale shaker, desander, desilter, vacuum degasser, centrifuge, sand pump, agitator and blender, etc., and can also be equipped with drilling chip recovery and waste liquid treatment devices for environmentally sensitive areas.

Solid control equipment focuses on the development of sand, mud, and vacuum degasser equipment with a small footprint, high efficiency, and long life, and is integrated with high-speed centrifuges to achieve automatic detection and control according to test results.

The solid control system consists of four shale shakers and two vertical cutting dryers (i.e. dry shakers), the four shale shakers and vertical cutting dryers are connected in parallel, and the drilling fluid returned from the well is distributed by the drilling fluid distributor to the four shakers and dryers for processing, and the solid particles separated by them are processed by the other. The dryer is treated to further dehydrate the particles. The leached liquid is recovered and the dried particles are expelled, and the dryer is actually a fine-mesh shale screen with a screen tilt of 10° to reduce liquid loss.

In recent years, the theoretical research and manufacturing process level of drilling fluid solid control equipment has been greatly developed, especially in the theoretical research of the working principle of the shale shaker and the working principle of the cyclone separator, which has reached or close to a very high level. There is a certain gap between the performance and life of solid phase control equipment and foreign solid phase control equipment, mainly in terms of materials, processing technology, processing accuracy, and the quality of general equipment (such as motors).

Application Principles of Drilling Mud zero discharge Technology

The application principles of drilling mud zero discharge technology involve the following steps:

1, Collection:

The drilling mud, which is a mixture of water, mud additives, and drill cuttings, is collected from the drilling operation. This mud contains contaminants that need to be effectively treated before discharge or reuse.

2, Separation:

The first step in the zero discharge process is to separate the solids (drill cuttings) from the drilling mud. This can be done using various techniques such as shale shakers, centrifuges, or hydrocyclones. The solids are then typically sent for further treatment or disposal.

3, Treatment:

The separated drilling mud undergoes a treatment process to remove contaminants and achieve the desired level of cleanliness. This treatment can involve physical separation techniques (such as centrifugation or filtration), chemical treatment (such as flocculation or coagulation), and thermal treatment (such as evaporation or thermal desorption).

4, Recycling and Reuse:

Once the drilling mud has been effectively treated, it can be recycled and reused in the drilling operation. This not only reduces waste generation but also helps reduce costs associated with procurement of new drilling mud.

5, Monitoring and Compliance:

The Functionality and Benefits of a drilling mud centrifuge in Drilling Operations

Solids control is a crucial aspect of drilling operations, as efficient removal of drilling solids from the drilling mud is essential for maintaining drilling fluid properties and optimizing overall drilling performance. One of the key tools used in solids control is a drilling mud centrifuge. In this article, we will explore the functionality and benefits of a drilling mud centrifuge in effectively separating and managing drilling solids during drilling operations.

1, Introduction to Drilling Mud Centrifuge in drilling operations:

A drilling mud centrifuge is a mechanical device that utilizes centrifugal force to separate solid particles from the drilling mud. It works on the principle of differential settling, where the centrifugal force exerted by the spinning bowl of the centrifuge causes the denser solids to settle and accumulate. At the same time, the lighter liquid phase (drilling mud) overflows and is collected separately. This separation process significantly enhances solids control and helps maintain the desired drilling fluid properties.

2, Efficient Solids Control:

The primary function of a drilling mud centrifuge is to remove fine solids from the drilling mud. This includes particles such as clay, silt, and colloidal materials that are difficult to separate using other solids control equipment. The centrifugal force generated by the spinning bowl of the centrifuge enables the effective separation of these fine particles, preventing their accumulation in the drilling fluid and maintaining its properties within desired specifications.

3, Enhanced Drilling Fluid Quality:

By effectively removing solid particles, a drilling mud centrifuge helps improve the quality and performance of the drilling fluid. The separation process ensures that the drilling mud maintains the required density, viscosity, and rheological properties necessary for efficient drilling operations. With better drilling fluid quality, operators can achieve improved hole stability, better drilling penetration rates, reduced wear on drilling equipment, and enhanced drilling efficiency.

4, Recovery of Valuable Fluids:

In addition to solid particle removal, a drilling mud centrifuge also facilitates the recovery of valuable drilling fluids from the separated solids. As the solids accumulate in the centrifuge bowl, the recovered drilling fluid is discharged and collected for reuse. This fluid recovery minimizes wastage, reduces the need for fresh drilling fluid, and lowers operational costs associated with fluid purchases and disposal.

5, Wide Range of Application of Mud Centrifuge in drilling operations:

Drilling mud centrifuges are versatile and can be used in various drilling applications and environments. They are effective in both oil-based and water-based drilling fluids and in challenging drilling conditions such as deepwater or high-angle drilling. Centrifuges can handle a wide range of drilling mud flow rates and accommodate different types and sizes of solid particles, making them adaptable to diverse drilling operations.

6, Optimized Solids Disposal:

After the solids have been separated from the drilling mud, they need to be properly disposed of. The drier solids obtained from the centrifuge are easier to handle and transport, reducing the volume and associated costs of waste disposal. Additionally, the drier solids are often less hazardous, simplifying regulatory compliance and minimizing environmental impact.

A drilling mud centrifuge is a vital tool in solids control during drilling operations. It effectively removes fine particles from the drilling mud, improves drilling fluid quality, and enables the recovery of valuable drilling fluids. With enhanced solids control, drilling operators can achieve better drilling efficiency, reduced downtime, and cost savings. Incorporating a drilling mud centrifuge into solids control practices are essential for maintaining optimal drilling fluid properties and ensuring smooth and successful drilling operations.

Common types of Oil-based Drilling Cuttings Processing Equipment

Oil-based drilling cuttings processing equipment refers to the machinery and systems used in the oil and gas industry to process and treat the drilling cuttings generated during the drilling of oil-based muds. These equipment are designed to separate the drill cuttings from the drilling fluid, recover valuable drilling fluid for reuse, and reduce the environmental impact of drilling waste. Here are some common types of oil-based drilling cuttings processing equipment:

1, Vertical Cuttings Dryer (VCD):

A vertical cuttings dryer is a key component in the cuttings processing system. It uses centrifugal force to remove drilling fluids from the cuttings. The cuttings are fed into the dryer, where they are rotated at high speeds to remove the liquid phase. The recovered drilling fluid is discharged for reuse, while the dried cuttings are further treated or disposed of.

2, Screw Conveyors:

Screw conveyors are used to transport the cuttings from one process unit to another. They are designed to handle the cuttings efficiently and continuously. Screw conveyors can be used to transfer the cuttings from the vertical cuttings dryer to the next stage of processing or for final disposal.

3, Decanter Centrifuge:

A decanter centrifuge is another essential piece of equipment used in oil-based drilling cuttings processing. It uses high-speed rotation to separate the finer solids and residual drilling fluids from the cuttings. The centrifuge works based on the principle of differential settling, where the heavier solids are forced to the outside while the lighter fluids move toward the center for recovery.

4, Thermal Desorption Unit (TDU):

In cases where the drilling cuttings contain high levels of hydrocarbons, a thermal desorption unit is employed. The TDU utilizes heat to vaporize and separate the hydrocarbons from the cuttings. The recovered hydrocarbons can be recycled or sold, while the treated cuttings are typically disposed of or used for alternative applications.

5, Shale Shakers:

Shale shakers are primary solids control equipment used to remove larger cuttings and solids from the drilling fluid. They consist of vibrating screens that allow the fluid to pass through while separating the cuttings. The separated cuttings are collected and further processed using other equipment.

6, Mud Tanks and Agitators:

Mud tanks are large containers used to store and process the drilling fluid. Agitators are installed within the tanks to keep the fluid properly mixed and prevent solids settling. The mud tanks provide a central location for the drilling fluid to be circulated and treated, while also allowing for the settlement and collection of cuttings.

7, Drying Shaker:

A drying shaker is similar to a shale shaker but with additional drying capabilities. It is used further to remove liquids from the cuttings after the initial treatment. The cuttings are passed over a vibrating screen, and the remaining drilling fluid is collected for further processing or recycling.

8, Cuttings Storage and Transport Systems:

Once the drilling cuttings are processed and treated, they need to be properly stored and transported for final disposal. This may involve specialized containers or skips that are designed to safely contain and transport the cuttings to approved waste management facilities.

It’s important to note that the specific combination and configuration of equipment can vary depending on the drilling operation, regulations, and environmental considerations. The selection and utilization of oil-based drilling cuttings processing equipment should comply with industry standards and local regulations to ensure effective treatment and minimize environmental impact.
