摘要
陕北油田区域构造上位于鄂尔多斯盆地,属于低渗透、特低渗透油田,实施压裂改造可以提高油田的整体开发效益。通过对姚店油田长6油层进行注水压裂改造,油井平均单井日产量提高了234%,稳产时间达3个月以上。研究表明特低渗透油层在注水受效后油层压力开始恢复时,对油层实施压裂,可以提高采收率,获得最好的增产、稳产效果。
Shanbei oil filed, which is located at Ordos Basin is typical extra - low permeability reservoir. Therefore, the measure of massive fracturing treatment is effective for developing this kind of reservoir. According to the research and the analysis on fracturing treatment for Chang 6 of Yaodian oil filed,it has shown that fracturing reform measurement is an enhance oil recovery, that is what happened after primitive water - injection and the recovery of formation pressure. It has proved to be effective on the increase and oil steady production with the proof of the statistics, as the production has increased 23% per well, staying steadily over three months.
