Drilling Fluid (Drilling Fluid) plays key roles in lubricating drill bits, carrying rock debris, stabilizing well walls, balancing formation pressure and the like in the petroleum and natural gas Drilling process. However, during use, the drilling fluid gradually fails due to mechanical action, chemical reaction and formation pollution, and finally becomes drilling fluid waste liquid. And since the drilling fluid carries the cuttings back to the surface, a large amount of fine particles remain (particle size <50 μm) even if separated by a vibrating screen, resulting in an increase in the solid phase content of the drilling fluid. And the high-solid-content waste slurry discharged by the sand remover, the mud remover, the centrifugal machine and other equipment can pollute the drilling fluid. The conventional treatment method is to remove drill cuttings in the drilling fluid waste liquid by sieving or filtering, and then separately treat the separated solid phase and liquid phase. The solid phase is generally subjected to a press filtration operation using a press filter so that the solid phase is completely dehydrated, and the liquid obtained by press filtration is recovered and mixed with the above-mentioned liquid phase, and then the residual substances in the liquid phase are separated out using an evaporative crystallization apparatus, a membrane separation apparatus or an activated carbon adsorption apparatus. Therefore, the purification treatment of the drilling fluid waste liquid requires a plurality of working procedures, and corresponding purification equipment is matched, so that the equipment investment cost is increased, the operation such as transportation, installation and maintenance is inconvenient, the portability and the maneuverability are weaker, the transportation, installation and maintenance cost is increased, the continuity of the drilling fluid waste liquid treatment is poorer, and the treatment efficiency is lower.
