Problems solved by technology

At present, there are many thixotropic agents on the market, but based on the different types of solvents used, the suspension performance of the same thixotropic agent system in different solvents is quite different, especially for the performance between oil phase and non-oil phase solvents The difference is particularly obvious, which also leads to the inability of existing thixotropic agents to achieve multi-purpose between oil ph

Abstract

The invention relates to a two-phase thixotropic agent and a preparation method thereof. The two-phase thixotropic agent comprises the following raw materials in percentage by weight: 49-71% of a solvent; 3%-5% of a cationic surface active agent; 1-3% of a nonionic surfactant; 1 to 3 percent of modified montmorillonite; the balance is positively charged suspended particulate matters; the weight percentage of the nonionic surfactant is consistent with that of the modified montmorillonite. The invention has the following beneficial effects: the suspending agent has a suspending effect in the initial stage of preparation and also has good flowability, and the suspending effect is better along with the increase of time.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a two-phase thixotropic agent and a preparation method thereof. Background technique [0002] In life and production, thixotropic agents are widely used in various daily necessities and industrial products, such as cosmetics, coatings, drilling fluids, etc. For different solution systems, researchers have developed different thixotropic agent systems to meet the suspension performance requirements of products. At present, there are many thixotropic agents on the market, but based on the different types of solvents used, the suspension performance of the same thixotropic agent system in different solvents is quite different, especially for the performance between oil phase and non-oil phase solvents The difference is especially obvious, which also results in the inability of existing thixotropic agents to achieve multi-purpose use between oil phase and non-o...
