摘要

渤海油田生产井大多采用大段防砂和笼统注采，生产井含水率上升比较快，化学调驱技术是治理此类问题的有效手段。为此研究了层内生气调驱技术并在渤海某油田D3井组进行了成功应用，现场应用后增油效果显著，取得了很好的经济效益。

Abstract

In most production wells in Bohai oilfield,large-section sand control and general injection-production methods are mainly used. The water cut of production wells increases rapidly. Chemical regulation and flooding technology is an effective means to deal with such problems. For this reason, the profile control and displacement technology of in-situ gas generation was studied and successfully applied in a D3 well group in Bohai oilfield. The oil production rate has been increased greatly after application, and good economic benefits have been obtained.
