中原油田研制的JS841酸性胶束液与酸有良好的配伍性,能够降低酸的表面张力及酸与油的界面张力。加胶束液的酸称为胶束酸。胶束酸对重质烃有渗透和溶解能力,用于油层酸化,则有胶束和酸的迭加效应,能解除油层内有机和无机堵塞物。故可进一步提高酸化效果用JS841胶束酸对44口井(油井18口、注水井26口)进行了酸化处理,总成功率为85,7%,累计增产原油22982吨,增加注水量354 584立方米实践表明,增产增注效果显著。
The JS841 acid micellar solution developed by Zhongyuan Oilfield has a good compatibility with the acid and can reduce the surface tension of the acid and the interfacial tension between the acid and the oil. Add micellar acid called micellar acid. Micellar acid has the ability to infiltrate and dissolve heavy hydrocarbons, which is used in the acidification of the oil layer. It has the superposition effect of micelles and acids, which can lift the organic and inorganic blockage in the oil layer. So it can further enhance the acidification effect. With JS841 micellar acid, 44 wells (18 wells and 26 wells) were acidified with a total success rate of 85.7%. Total cumulative production of crude oil increased by 22,982 tons and water injection volume increased by 354 584 Cubic practice shows that the effect of significant increase stimulation.
