Sewage utilization method and system based on recyclable clean fracturing fluid system

Abstract

The invention discloses a sewage utilization method and system based on a recyclable clean fracturing fluid system. The method comprises the following steps: obtaining a water quality standard of the clean fracturing fluid system; obtaining first sewage information; obtaining a first preprocessing instruction; performing standard detection on the first sewage according to the first preprocessing instruction to obtain second sewage component information and second component content information of the first sewage information; obtaining a first treatment scheme through a sewage treatment scheme matching model; treating the first sewage according to the first treatment scheme to obtain first purified water; and mixing the first purified water with a recyclable clean fracturing fluid thickening agent. The technical problems that in the prior art, a large amount of sewage is generated when oil field yield increase is achieved through a fracturing technology, methods such as filtering and chemical flocculation are usually adopted for sewage treatment, the whole sewage treatment process is complex and long in duration, and manpower and material resources are used for treatment, and the cost is high are solved.

Description

technical field [0001] The present application relates to the field of computer application technology, and in particular to a sewage utilization method and system based on a recyclable clean fracturing fluid system. Background technique [0002] At present, many domestic oil fields have entered the middle and late stages of oil exploitation, so improving the recovery rate of oil fields is one of the important tasks of domestic oil fields. Oil and gas well fracturing operation technology refers to the technology of using water conservancy to form a fracture in the oil and gas layer during oil or gas recovery. It is one of the main measures to increase production in the middle and late stages of oil and gas recovery. In the process of oil recovery, the fracturing technology has a very obvious effect on increasing production and is widely used in the development of various oilfields. However, the application of this technology makes the unreturned fracturing fluid enter the se...
