Abstract

The invention relates to the technical field of coating agents in petrochemical industry and provides a polymer emulsion strong coating agent. An AM / AAK / AMPS terpolymer comprises acrylamide, potassium acrylate, 2-acryloylamino-2-sodium methylacrylsulfonate, an emulsifying agent, an initiator, an oil phase and water. The polymer emulsion strong coating agent comprises the following raw materials in parts by weight: 90-94.5 parts of the AM / AAK / AMPS terpolymer, 5-9.9 parts of small positive ion quaternary ammonium salt and 0.1-0.5 part of an anti-gelling agent. The polymer emulsion strong coating agent is good in temperature resistance, salt resistance and shearing resistance, has strong coating inhibition performance and excellent working performance, can meet the requirements of construction in low-temperature regions and has a wide application range and when the polymer emulsion strong coating agent is applied to an HRD non-clay-phase drilling fluid system, the cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of coating agents in petrochemical industry, and relates to an AM / AAK / AMPS terpolymer and polymer emulsion strong coating agent and a preparation method thereof. Background technique [0002] Polymer emulsion strong coating agent is a kind of liquid polymer coating agent, which mainly plays the role of inhibiting coating in drilling fluid, and belongs to the essential component of water-based drilling fluid in drilling fluid treatment agent in the field of petroleum drilling. Polymer coating agent is used in drilling fluid, which is called polymer drilling fluid system. This system has been used in my country for 20 to 30 years since the 1970s. The role of current polymer coating agents in water-based drilling fluids is like "salt" in our lives, which plays a very important role. The mechanism of high-molecular polymers inhibiting shale hydration and dispersion is generally believed to be that polymer macro...
