Abstract

The invention relates to a shearing-potentiation organic soil for drilling, belonging to the technical field of organobentonite modification in petrochemical industry. The preparation method comprises the following steps: preparing required amounts of bentonite, sodium carbonate, sodium hydroxide or potassium hydroxide into a bentonite suspension; preparing a bis-quaternary ammonium salt cationic surfactant, an auxiliary dispersant, a nonionic surfactant, white oil and water into a composite modifier emulsion; stirring with tetrabutylammonium bromide and other secondary modifiers at 60-80 DEG C for 60-120 minutes, drying, and pulverizing to obtain the shearing-potentiation organic soil for drilling. The shearing-potentiation organic soil for drilling has the advantages of favorable shearing-potentiation effect and high ratio of dynamic shear force, is more suitable to be used in an all-oil-base low-solid drilling fluid system, has favorable suspension and cutting carrying effects.

Description

technical field [0001] The invention relates to the technical field of modification of organic bentonite in petrochemical industry, and relates to a cutting type organic soil for well drilling and a preparation method thereof. Background technique [0002] Organic clay (also known as organic bentonite) is mostly obtained by ion exchange between cationic quaternary ammonium salts of different structures or organic solvents with ion exchange capabilities and sodium bentonite, and can form gels in various organic solvents, oils, and liquid resins , with good thickening, thixotropy, suspension stability, high temperature stability, lubricity, film-forming, water resistance and other characteristics, in the synthesis of organic-inorganic nanocomposites, coatings, textiles, inks, wastewater treatment, casting, It is widely used in industries such as high temperature grease, drilling, daily cosmetics, pesticides, plastics and rubber. Using natural bentonite to synthesize organic s...
