A cross-linking agent production device based on high-pressure filtration for oil fields

Abstract

The present invention relates to the technical field of oil field cross-linking agent production equipment, in particular to a cross-linking agent production device based on high-pressure filtration for the oil field through double-chamber agitation and classification filtration, including an upper chamber, a lower chamber, a filter cartridge, a high-pressure replacement The air port, the circulation stirring part, the mixing and stirring part, the filter assembly and the purification net, the circulation stirring part is arranged in the upper chamber, the mixing and stirring part and the purification net are arranged in the lower chamber, and the filter assembly is arranged in the filter cartridge. In the present invention, the oilfield crosslinking agent raw material is evenly stirred and mixed through the circulating stirring part and the mixing stirring part, the agglomeration and impurities in the oilfield crosslinking agent raw material are separated by the filter assembly, and the oilfield crosslinking agent is purified through the purification network. The high-pressure air exchange port carries out a regular inflation and suction process in the lower chamber, and the pressure cycle in the upper chamber and the lower chamber increases and decreases, which increases the filtration and purification efficiency of the device for oilfield cross-linking agents.

Description

technical field

[0001] The invention relates to the technical field of oilfield crosslinking agent production equipment, in particular to a crosslinking agent production device for oilfields based on high-pressure filtration. Background technique

[0002] The cross-linking agent is also called a bridging agent. The cross-linking agent is an important part of the polyhydrocarbon photoresist. The cross-linking agent will generate diradicals after exposure. Resin-like interactions form bridge bonds between polymer molecular chains and become insoluble substances with a three-dimensional structure. Due to the different mining environments in my country's oilfields, in order to prevent danger during the mining process, it is necessary to borrow a variety of materials at the beginning of the well. Auxiliary reagents are used to drill down production wells. As an important auxiliary reagent, cross-linking agents have been widely used in the field of oilfield exploitation. Different c...
