Abstract

The invention discloses an integrated waste drilling mud treatment system capable of treating while drilling. The integrated waste drilling mud treatment system capable of treating while drilling comprises two collecting tank bins, a multi-stage solid-liquid separation module, a deep treating module and a conveying system. The multi-stage solid-liquid separation module comprises a centrifugal machine, a liquid transfer bin, a coarse-mesh dryer and a fine-mesh dryer, wherein the mesh number of the fine-mesh dryer is larger than that of the coarse -mesh dryer, and a liquid outlet of the centrifugal machine is connected with the liquid transfer bin. The deep treating module comprises a water treating regenerator and a liquid recovery tank, and a liquid outlet of the water treating regenerator is connected with the liquid recovery tank. A feeding port of the coarse-mesh dryer is connected with the first collecting tank bin, and a feeding port of the fine-mesh dryer is connected with a liquid outlet of the coarse-mesh dryer and the second collecting tank bin. The integrated waste drilling mud treatment system capable of treating while drilling has the advantages that on one hand, use of solidifying chemical agents can be reduced greatly, so that harmful solid discharge is reduced fundamentally; on the other hand, liquid recovery ratio after treatment is increased greatly, so that waste drilling mud is reduced fundamentally.

Description

technical field [0001] The invention relates to an integrated treatment system for drilling waste mud. Background technique [0002] During the drilling process of oil and gas exploration and development, the shale shaker, desander, desilter and centrifuge in the drilling facility will produce mud, which is composed of three parts: solid phase, liquid phase and chemical treatment agent, which contains A large number of colloidal suspension systems of clay, weighted materials, various chemical treatment agents, sewage, dirty oil and drilling cuttings will definitely cause immeasurable harm to the natural environment if they are not treated. [0003] At present, there are three domestic treatment methods for waste drilling fluid: direct discharge, large circulation pool sedimentation and solidification treatment. [0004] (1) Direct discharge method [0005] Some waste drilling fluids can be discharged directly into the environment, but this is limited to low-toxic or non-to...
