Waste solidified treatment device for drilling

Abstract

The invention relates to a method for treating drilling wastes in petroleum and gas exploitation, especially a solidification treatment method and an apparatus thereof. The treatment method adopts delivering the drilling wastes to a high speed disintegrator to smash, at the same time spraying firming agent to the high speed disintegrator. The apparatus comprises a delivery conveyor within a receiving bucket, a bucket elevator, a feeding spiral conveyer, a high speed disintegrator and a firming agent conveyer. The invention smashes wastes to form numerous small particle, after that, carries out physico-chemical reaction with the firming agent, and packages the small particle. Accordingly, the invention has good solidifying effect correspondingly, can reduce firming agent application amount, wherein the solidified body extract will not pollute the environment. Meanwhile, the apparatus of the invention with high mechanization degree, may form automatic integration, is convenient for achieving solidification treatment along with the drilling process without generating environment pollution.

Description

Drilling waste solidification treatment device technical field The invention relates to a treatment device for drilling waste in oil and natural gas exploitation, especially a solidification treatment device. Background technique With the massive exploitation of oil and gas, the disposal of drilling waste fluid has become a major problem due to serious pollution. At present, centrifuges are generally used for solid-liquid separation in the treatment of drilling waste fluid, and the separated liquid is treated with gel breakers and micro-electrolysis; the separated waste (mainly mud) is solidified by adding a curing agent. The general process of the existing curing treatment is to directly add the curing agent into the waste and stir. Correspondingly, there are problems such as high amount of curing agent, unstable curing effect, easy occurrence of leachate in the cured body, which cannot meet environmental protection requirements, inconvenient treatment of the cured body,...

AI Technical Summary

Problems solved by technology

Correspondingly, there are problems such as high amount of curing agent, unstable curing effect, easy occurrence of leachate in the cured body, which cannot meet environmental protection requirements, inconvenient treatment of the cured body, etc., and the existing curing treatment device is simple, labor-intensive, and the processing while drilling causes relatively large pollution
