Abstract

The invention discloses a device system to recover and re-use the drilling mud, which comprises connected by turns: a storage tank to store the waste drilling mud, a vibration screen for coarse purification, a hydrocyclone to separate the mud conveyed by a mud pump and discharge the particulate from its lower end, a first-stage centrifuge for filter and purification, a microwave oven to dry the mud, a crusher to crush the mud again, and an automatic packaging machine to pack and recover the mud. This invention is simple and convenient, has low cost and no pollution danger, and brings hundred millions economic benefits every year.

Description

technical field [0001] The invention relates to recovery of geological exploration mud, and is particularly suitable for a device system for recovery, purification and reuse of drilling mud and a method for purification and recovery of mud. Background technique [0002] Thousands of new oil and gas wells are drilled in my country every year, and the waste mud generated after the completion of each oil and gas well is about 70-80 cubic meters, with a water content as high as 60%. This waste mud is a mixture containing a variety of harmful substances, which can directly cause soil compaction, making it difficult for plants to absorb water from the soil, which is not conducive to plant growth. Organic components in waste drilling fluids are the most toxic to plants because they contain oils and lignosulfonates. The fungicides in the waste drilling fluid contain toxic components such as thiamine and amine, which are harmful to fish and birds, and have potential toxicity to the ...
