摘要
针对目前石油开采现场上所应用的解堵剂不能同时解除复合垢堵塞的解堵单一性.配制出一种新型多功能水包油型解堵酸液.该解堵酸液是在适当的表面活性剂作用下,以15%的盐酸作为外相,以高溶解性能的油为内相所形成的乳化体系,其配方为0.5%OP-10+0.5%Span80+0.2%Tween80+0.06%咪唑啉+0.01%十二醇,油相含量和水相含量相等.试验研究表明,将这种乳状酸液注入地层后,对地层中无机垢(碳酸钙、碳酸镁等)和有机垢(主要是胶质沥青)有着较好的溶蚀能力,以达到解除油层堵塞,恢复和提高地层渗透率、增强地层流体导流能力的目的.
Aiming at the oneness of acid to deliquesce stratum-jam applied in scene at the present time, which is incapable of deliquescing complex dirty simultaneously, this article confects a new multifunctional O/W acid. This acid is an emulsified mixture containing 15% hydrochloric acid function of some proper exterior active reagent. It is as its extro-posture, high dissolved oil as its internal state under the composed of 0.5% OP-10, 0.5% Span80, 0.2% TweenS0, 0.06% imidazole and 0. 01% twelve-alcohol, and the content of oil is equal to the acid content. It can be indicated that this acid has good ability of resolving mineral （CaCO3, MgCO3） and organic compound （mainly colloidal bitumen） when it was poured into the stratum, so that it can deliquesce oleic stratum-jam, resume and improve the penetrability of stratum, boost the ability of liquid flowing up.
