Fracturing flow-back fluid pretreatment device facilitating grating cleaning

Abstract

The invention provides a fracturing flow-back fluid pretreatment device convenient for cleaning a grating, and relates to the technical field of fracturing fluid treatment.The fracturing flow-back fluid pretreatment device comprises a transfer box, a filtering storage tank is formed in the transfer box, a transfer through hole is formed in one side of the filtering storage tank in a penetrating mode, and an adjusting assembly is installed on one side of the inner wall of the filtering storage tank; and a positioning rotating sleeve rod is installed on the other side of the inner wall of the filtering storage tank, and a placement assembly is installed between the positioning rotating sleeve rod and the adjusting assembly. Through cooperation of the clamping buckle assembly and the placement assembly, the collected impurities can be transferred into the clamping buckle mounting frame, so that the cleaning effect of the device is effectively ensured, and the problem that a large number of impurities are generated under the condition that the grating is used for a long time is effectively solved; and therefore, impurities such as large particles are remained in the fracturing flow-back fluid under the subsequent treatment condition, and the fracturing flow-back fluid is influenced.

Description

technical field [0001] The invention relates to the technical field of fracturing fluid treatment, in particular to a pretreatment device for fracturing flowback fluid which is convenient for grid cleaning. Background technique [0002] Fracturing fluid refers to a heterogeneous and unstable chemical system formed by various additives in a certain ratio. It is a working fluid used in fracturing oil and gas reservoirs. Its main function is to transmit the high pressure formed by ground equipment. into the formation to break the formation to form fractures and transport proppant along the fractures. In use, it is necessary to use a grid to pre-filter the fracturing flowback fluid, such as the one proposed by the patent application number CN201420197290.9 The environmental protection pretreatment device for fracturing flowback fluid mainly solves the problems of incomplete treatment and environmental pollution in existing fracturing flowback fluid treatment devices. It is char...
