Abstract

The invention discloses a drilling waste slurry integrated treatment system. The drilling waste slurry integrated treatment system comprises an automatic classification and collection module, a multi-grade solid-liquid separation combined module and a solid-phase conveying system, wherein the automatic classification and collection module comprises a plurality of rock debris slurry removing machine and slurry storage tank combinations which are connected in series; the multi-grade solid-liquid separation combined module comprises a sand scrap removing machine, a multifunctional adjusting tank and a water treatment regeneration device; the multifunctional adjusting tank comprises a medicine adding treatment region and a clean water temporary storage region; and the solid-phase conveying system is connected with a curing agent adding device. The high-grade waste slurry treatment combined system integrates a plurality of functions of collecting slurry, storing, carrying out solid-liquid separation, purifying the slurry, carrying out solid-phase conveying and field curing, recycling a liquid phase and the like; the waste slurry can be scientifically and effectively classified and treated by classes in a drilling process; and a drilling and curing innovative pattern is realized, and the national blank in the aspect is filled. By virtue of the drilling waste slurry integrated treatment system, the use amount of curing medicaments can be greatly reduced, and the recycling rate of a treated liquid phase also can be greatly improved.

Description

technical field [0001] The invention relates to a drilling waste mud treatment device. 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-toxic drilling flu...
