Mud treatment system is used in bridge pile foundation engineering, trenchless crossing engineering and oil drilling engineering construction
The mud treatment system is mainly used in the construction of bridge pile foundation engineering, trenchless crossing engineering, oil drilling engineering and underground tunnel shield engineering.
Mud, also known as drilling fluid, is composed of liquid and clay, supplemented by additives, mainly plays the role of protecting the hole wall, carrying drilling slag out of the hole and cooling the drilling tool. In the process of drilling mud, because the drilling slag continues to enter the mud, the specific gravity, viscosity, sand content and so on change, can not meet the requirements of mud performance, it must be treated or purified, mainly for solid-liquid separation, the drilling slag in the mud is separated and discharged after recycling.
Purification methods are mainly sedimentation tanks and mechanical equipment. The use of sedimentation tank treatment needs to occupy some land; The high water content of the drilling slag removed from the sedimentation tank makes the mud spill, the construction environment is harsh, and may cause environmental pollution or water pollution and other public hazards. The environmental problems brought by the mud are getting more and more attention. At present, the main mud treatment technology is vibrating screen, desander, desander, centrifuge, etc. According to the occasion of mud treatment, the composition of drilling slag and the requirements of mud performance, different process combinations are adopted.
