摘要
Abstract
Air foam flooding has very bright future because of its comprehensive displacement mechanism and unique air source predominance. To apply the technique successfully in high temperature reservoir, this paper conducted study on the temperature resist air foam system. By examining the foam volume and liquid separating half-life period of ten temperature resist surfactants at 110℃ and 6 × 104 mg/L, we screen out the anionic-nonionic surfactant LS which has satisfactory high temperature foam performance. We evaluate the foam performance of LS at reservoir environment and the result shows that LS could form more abundant foam at high pressure seal condition than atmospheric pressure; the persistent shear of porous media and plenty air flow is in favor of LS fully playing its foam performance. By adding foam stabilizer WP whose concentration is beyond 0.1 %, the liquid separating half-life period of LS could be evidently enhanced. After aging under 110℃ and 6× 104 mg/L for 90 d, the liquid separating half-life period of 0.2%LS+0.1%WP only shortens by 20%, and its IFT with Guan80 crude oil remains 10-2 mN/m. Furthermore, the emulsification capability of air foam is satisfactory, oil and water being separated almost completely after standing short length of time.关键词
