Crosslinking agent production device based on high-pressure filtration for oil field

Abstract

The 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 an oil field through double-cavity stirring and graded filtration, which comprises an upper cavity, a lower cavity, a filter cartridge, a high-pressure scavenging port, a circulating stirring part, a mixing stirring part, a filter assembly and a purification net, the circulating stirring part is arranged in the upper cavity, the mixing stirring part and the purifying net are arranged in the lower cavity, and the filtering assembly is arranged in the filtering cylinder. Oil field crosslinking agent raw materials are uniformly stirred and mixed through the circulating stirring component and the mixing stirring component, cakes and impurities in the oil field crosslinking agent raw materials are separated through the filtering assembly, an oil field crosslinking agent is purified through the purifying net, and the lower cavity is inflated and sucked at regular time through the high-pressure scavenging port; the pressure circulation in the upper cavity and the lower cavity is increased and decreased, so that the filtering and purifying efficiency of the device on the oil field cross-linking agent is improved.

AI Technical Summary

Benefits of technology

This patented technology helps mix different types of chemicals together with an oily substance called guar gum or another type of resin that can be added into well drilling fluids during exploration operations. By mixing these materials through a special mechanism, they become evenly distributed throughout the fluid before being injected downhole. A filtering device separates out any solid particles suspended therefrom while allowing liquor-like liquid matter (oil) passes therethrough. An adhesive bag captures small pieces of metal found on top of it. These tiny items help keep them separate when filtered properly. After cleanup, this process removes unwanted soluble compounds like salts and other harmful metals. Overall, this method improves the quality and performance of the cement job without adding extra components such as water or sand.

Problems solved by technology

This patented technology describes how to create a special type of chemical called a cross linking agent (cross-link) when needed inside certain resins made from petroleum products like crude oils. These cross-Linkers can help improve their properties by forming strong connections within them without being dissolved into water. However, this method has limitations due to factors such as impurity content and difficulty in achieving consistently good quality product over time.
