| 摘 要： | 针对河南油田赵凹区块注水效果不好,欠注严重,酸化效果不理想的实际情况,开展了储层伤害因素分析和酸化增油技术研究,进行了酸液体系的配方优化,优选出的酸液具有对金属腐蚀性小,与地下流体配伍性好,对岩屑溶蚀率高的特点。现场实验取得了较好的增注效果,3口井实施有效率100％,注水压力下降了1-8 MPa。

| Abstract: | In view of poor waterflood and unsatisfactory acidizing effect in Zhaowa block in Henan oilfield, analysis of adverse reservoir factors and research of acid stimulation technology have been carried out The optimization of acid fluid system shows that the optimized acid fluid has little corrosive attack towards metal as well as strong dissolution ability towards debris and it is in good matching with underground fluid. Three field experiments were carried out, achieving an effective successful rate of 100% and decreased injection pressure of 1 - 8MPa. |
