The invention relates to a composite metal ion polymer drilling fluid treating agent and a preparation method thereof. The treating agent comprises the following ingredients by weight percentage: 30-35% of acrylamide, 0.5-0.7% of 2-acrylamide-2-methyl propane sulfonic acid, 2.5-3.5% of acryloyloxyethyl trimethyl ammonium chloride, 2-3% of sodium carbonate, 0.5-0.7% of a lamellar mixed metal hydroxide and the balance of deionized water, wherein the polymerization-hydrolysis reaction is carried out on acrylamide, sodium carbonate and water in a polymerizing pot to obtain polyacrylamide; polyacrylamide and other additives are put into a kneading machine for modifying. The preparation method comprises the following processes: ingredients dosing, the polymerization-hydrolysis reaction, kneading and modifying, drying, granulating, grinding, screening, examining and packaging. By combining metal polymers with water-soluble high polymers, the treating agent has the advantages of positive charge colloid and the characteristics of water-soluble high polymers; the preparation method is moderate in conditions during the preparation process, free of pollution on the environment, less in equipment investment and low in production cost.
Description
technical field [0001] The invention belongs to the technical field of oilfield chemicals, and relates to a composite metal ion polymer drilling fluid treatment agent and a preparation method thereof. Background technique [0002] In drilling engineering, accidents caused by the failure of drilling fluid wall plugging occur frequently, and drilling leakage is particularly serious in the exploration of oil and natural gas deposits. Therefore, drilling fluid is a key link in drilling engineering. With the gradual increase of drilling depth and difficulty, drilling fluid plays an increasingly important role in ensuring safe, high-quality and fast drilling. Composite metal ion polymer drilling fluid treatment agent is a chemical additive added to improve and stabilize drilling fluid performance and meet drilling needs. It is the core component of drilling fluid, and a small amount of addition can improve the performance of drilling fluid. Great impact. [0003] The publication...
