摘要
针对文明寨、马寨油田非均质性严重、层间矛盾突出、油井能量低、笼统酸化酸液易进入高渗透层、卡封分层酸化应用范围窄且无法改善层间矛盾的现状, 研制应用了暂堵分层酸化工艺, 工艺成功率100% , 有效率85-7% , 投入产出达1∶10-2 , 取得了好的效果。
According to the problem of serious heterogeneity, conflicts among reservoirs, low energy of wells, etc.of Wenmingzhai and Mazhai oil fields, this paper studies and applied the technique of temporary plugging separate zone acidizing with 100% of success, 85.7% of effectiveness and 1:10.2 of input output.
