Liquid supply method suitable for fracturing construction in mountain area

Abstract

The invention discloses a liquid supply method suitable for fracturing construction in a mountain area. By adopting combined fracturing fluid tanks and combining with specific on-site terrains of themountain area, fluid preparation is carried out. The method includes the steps that a water source for first-level water supply is introduced into a mixing preparation device through a water pump, themixing preparation device can achieve continuous mixing, preparation and conveying of water, acid liquid, dry powder or pasty fluids and various liquid additives, and the acid liquid, the dry power or the pasty fluids and the liquid additives are added according to proportions and mixed and stirred with clean water; a qualified fracturing fluid after mixing preparation is conveyed into one or more combined fracturing fluid tanks by an acidproof pump for storage, and the combined fracturing fluid tanks are connected with one another through valves and pipes. Liquid supply by means of one modular combined fracturing fluid tank is achieved, the other combined fracturing fluid tank carries out fluid preparation and storage, and fracturing operation can be carried out continuously. According to the requirements of fluid supply amount, combination of the tanks can be freely changed to meet all construction demands in a fracturing block of the mountain area.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a liquid supply method suitable for fracturing construction in mountainous areas. Background technique [0002] In the process of shale oil and gas exploitation, fracturing technology is an important means to increase the production of oil and gas wells and shale gas wells, especially in shale gas well fracturing construction, the use of fracturing construction is very common, and with the progress of construction technology, some Scholars have proposed a new fracturing mode "factory" fracturing; the so-called factory fracturing is like an ordinary factory, in a fixed place, continuously pumping fracturing fluid and proppant; its advantages are It can shorten the overall construction period of the block, reduce the unit gas production cost; greatly improve the utilization rate of fracturing equipment, reduce equipment relocation and installation, reduce the ...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the large demand for fracturing fluid, there is a large demand for buffer tanks for storing fracturing fluid, and a large number of clean water tanks are required at the same time;

[0007] 2. The traditional liquid preparation process takes a long time to prepare, and the liquid is prepared first before construction. Due to the small storage capacity and large quantity of the liquid storage tank, after the fracturing construction of one layer, the liquid preparation must be restarted, which cannot meet the requirements of continuous long-term fracturing;

[0008] 3. There are many storage tanks for storing fracturing fluid and manual operation is required, and the labor intensity of on-site staff is high;

[0009] 4. The fracturing fluid tank and clean water tank occupy 1/3 of the
