The drilling mud circulation system needs to understand the following 6 points: the role of the mud circulation system, equipment composition; the layout, classification and system of the mud circulation system, etc.
The role of the mud circulation system
The drilling mud circulation system plays the role of purifying and recycling the circulating mud in the drilling rig. The mud circulation system can prepare mud suitable for drilling. It mainly uses solid control equipment such as vibrating screens to filter the particles in the mud in a graded manner, so that the mud performance meets the drilling requirements.
Mud circulation system equipment composition
The drilling mud circulation system is an important part of the drilling rig. The drilling mud circulation system includes: mud vibrating screen, sand and mud removal machine, vacuum remover, drilling fluid centrifuge, agitator, mud tank, jet mixing, sand pump, electronic control, liquid-gas separation, etc.
Mud circulation system design
The drilling mud circulation system is designed for different drilling conditions. Some drilling areas are extremely cold, such as Russia, which requires a mud circulation system that can withstand the cold; for example, in the Middle East, the temperature is very high, and the mud circulation system needs to be designed to withstand high temperatures. For example, for desert areas, the mud circulation system can be designed to prevent wind and sand erosion;
Mud circulation system layout
The layout of the drilling mud circulation system can also be designed according to the working conditions of the drilling site. For example, if the drilling site is small, the mud circulation system can be arranged in a row; if the drilling site is open, the mud circulation system layout can be arranged side by side + in a row; if the drilling site needs to be moved, the mud circulation system can be fully implemented side by side;
Mud circulation system classification
Drilling mud circulation system is divided into 1000HP drilling rig mud circulation system for drilling rigs with a drilling depth of 4 kilometers; 1500HP drilling rig mud circulation system for drilling rigs with a drilling depth of 5 kilometers; 2000HP drilling rig mud circulation system for drilling rigs with a drilling depth of 7 kilometers; 3000HP drilling rig mud circulation system for drilling rigs with a drilling depth of 9 kilometers, etc. according to different types of drilling rigs.
Mud circulation system
Drilling mud circulation system can be divided into oil-based mud circulation system and water-based mud circulation system according to the drilling mud system. Oil-based mud circulation system is mainly used for ultra-deep well and directional well drilling. Water-based mud circulation system is mainly used for shallow drilling with low requirements for drilling mud.
