Foam washing fluid and preparation method thereof
The invention relates to foam washing fluid, which is applied to an oilfield development and washing work process. The foam washing fluid is characterized by comprising the following components by weight: 3.5 to 6 percent of hexadecyl-octadecyl trimethyl ammonium chloride, 18 to 30 percent of thioalcohol polyoxyethylene ether SSA-80, 8 to 12 percent of polyoxyethylene (10) octyl phenol ether, 1 to 2 percent of potassium chloride, 0.05 to 0.1 percent of fluorocarbon surfactant FC-3B, 0.5 to 1 percent of vitamin A, 0.05 to 0.1 percent of fluorocarbon surfactant FN-3, and the balance of water. The foam washing fluid has the effects that: when an oil well is thermally washed, the foam washing fluid is added into well washing fluid, and the oil well does not generate well killing phenomenon; and when a water injection well is washed, the foam washing fluid is evenly added into injection fluid, then dead oil in a shaft can be thoroughly washed out, and simultaneously, the aim of eliminating the pollution of a near wellbore zone is achieved.

The preparation method comprises the following steps: (1) adding montmorillonite into deionized water to obtain a suspended montmorillonite aqueous solution, adding a phosphoric acid solution of octadecyl trimethyl ammonium chloride, heating and stirring to obtain organic montmorillonite; (2) magnetically stirring the organic montmorillonite, polyaniline and hydrochloric acid solution together, dropwise adding an ammonium persulfate solution to obtain a green mixed solution, taking out, washing, drying and grinding to obtain a polyaniline-montmorillonite composite material; (3) hydrolyzing a coupling agent into an aqueous solution of acetone, adding tetrapod-like zinc oxide whiskers, ultrasonically stirring to obtain modified zinc oxide whiskers; (4) mixing ABS resin, a compatilizer, the polyaniline-montmorillonite composite material to obtain a premix; and (5) extruding and granulating the premix to obtain a granular material and drying to obtain the ABS resin based material.
