The function of the Drilling Mud Recovery System
The drilling mud recovery system is mainly used to separate solid particles from the mud generated during drilling or construction, achieving purification and recycling of the mud, thereby reducing construction costs and meeting environmental protection requirements. Drilling Mud recovery systems are widely used in trenchless engineering and oil drilling. Its core objective is to treat the slurry through multiple solid control devices (such as shale shaker, cyclones, and centrifuges). Remove impurities such as drill cuttings from it to restore the reusable performance of the mud.
The drilling mud recovery system not only enhances operational efficiency but also complies with increasingly strict global environmental protection regulations. For instance, it has become a standard device in on-site applications such as horizontal directional crossing (HDD) and coalbed methane extraction.
TR Solids Control has passed multiple international certifications including API, ISO and CE. The mud recovery system meets the export requirements.
Main functions and workflow of drilling mud recovery system
1. Large drill cuttings are initially screened out through shale shaker, and then fine particles are further removed by desander, desilter or centrifuge.
2. The cleaned base liquid can be remixed by adding new mud materials to meet the standards for reuse.
Resource recycling.
3. The separated clear water can be used for dust suppression, concrete curing or re-preparation of slurry.
The solids control system and solids control equipment produced are exported to many countries in the Middle East and Southeast Asia.
The Components of Solids Control System
Describe the Components of the solids control system
The solids control system is composed of multi-stage purification equipment, auxiliary equipment and pipeline systems. All levels of solids control equipment work in collaboration to achieve purification from coarse to fine.
The Components of Solids Control System
- Mud Shale Shaker:
Primary Solids Control equipment is also the “first line of defense” of the solids control system. The large particle cuttings (with a particle size of ≥74μm) in the drilling fluid are separated by high-frequency vibration.
The processing volume is usually 1.2 to 1.5 times the circulation volume of the drilling fluid, ensuring the efficient operation of subsequent equipment.
mus shale shakers can be classified into linear shale shakers and elliptical shale shakers. elliptical shale shakers are widely used in deep Wells and horizontal well drilling. it features high screening efficiency and strong processing capacity. - Desander:
Secondary Solids Control equipment. The desander adopts the principle of hydrocyclone to separate sand particles with a diameter of 20-74μm from the drilling fluid. It is usually used in conjunction with shale shakers. The sand grains separated by the cyclone fall into the small vibrating screen below to further recover the drilling fluid. - Desilter：
The third level in the solids control system. The sludge separator separates fine sludge particles of 10-20μm. The shaker screens of the deslimer is generally configured with 120 mesh. The sand removal cyclone has a smaller diameter and higher separation accuracy. It can effectively reduce the mud content of drilling fluid and maintain the stability of rheological properties. - Decanter Centrifuge：
Four-level deep Solids Control equipment. Solid-liquid separation is achieved by utilizing centrifugal force. Centrifuges are mainly used to separate ultrafine particles of 5-10μm. It is suitable for precision drilling scenarios with extremely high requirements for drilling fluid performance. It is mainly used for shale gas development and deep-sea drilling. It can enhance the reuse rate of drilling fluid.The centrifuge is components of solids control system.
Other equipment in the Components of Solids Control System：
The Components of Solids Control SystemIncluding drilling fluid tank, agitator, sand pump and vacuum degasser. Together, they form complete solids control system.
