A hydraulically driven fracturing skid

Abstract

The present invention provides a hydraulically driven fracturing skid, which includes a fracturing skid body and a pretreatment device. The pretreatment device includes several flow diversion devices and external treatment tanks. The flow diversion device includes a straight line pipe and a branch branch pipe. An electric valve 1 is installed on the diversion branch pipe, and several through holes are provided on the edge of the top of the outer treatment tank, and one ends of the straight pipes of the plurality of said diversion devices respectively pass through several through holes and are fixedly installed in the through holes, The design of the hydraulic transmission type fracturing skid is reasonable, the outer cylinder and the inner cylinder cooperate with each other, and several raw material tanks are installed on the top of the outer treatment tank, and raw materials can be added in different orders according to the coordination and configuration requirements of drilling fluid, so that Make the drilling fluid reach a better state, and can improve the production efficiency of the drilling fluid.

Description

technical field [0001] The invention belongs to the technical field of oilfield equipment, in particular to a hydraulic transmission type fracturing skid. Background technique [0002] The fracturing skid is an important equipment for increasing the permeability of oil and gas layers, thereby increasing the yield of oil and gas wells, and injecting high-pressure liquid into the formation. It can pump various operating media such as clean water, mud liquid, surfactant or high-viscosity liquid. When sanding and fracturing the formation, when adding multiple media, it is necessary to mix the media. If not mixed, the drilling fluid is more likely to produce lumpy polymers, and it is impossible to obtain dispersed and uniform fracturing in a short period of time. Drilling fluid, however, the existing fracturing skids cannot pretreat the raw materials, the mixing efficiency is low, and it is not possible to selectively pre-mix two or more raw materials according to the properties ...

[0002] The fracturing skid is an important equipment for increasing the permeability of oil and gas layers, thereby increasing the yield of oil and gas wells, and injecting high-pressure liquid into the formation. It can pump various operating media such as clean water, mud liquid, surfactant or high-viscosity liquid. When sanding and fracturing the formation, when adding multiple media, it is necessary to mix the media. If not mixed, the drilling fluid is more likely to produce lumpy polymers, and it is impossible to obtain dispersed and uniform fracturing in a short period of time. Drilling fluid, however, the existing fracturing skids cannot pretreat the raw materials, the mixing efficiency is low, and it is not possible to selectively pre-mix two or more raw materials according to the properties of the raw materials, the processing efficiency is low, and there is no The easily reacted or aggregated raw materials can be treated separately, which affects the quality and processing efficiency of drilling fluid. Therefore, the present invention proposes a hydraulic transmission type fracturing skid
