为解决钻井轨迹偏离油层,常规射孔穿深不足于穿透隔夹层,剩余油开采难问题,研究了多级复合火药深穿透射孔技术.为了封堵出水层段,在射孔炮眼环境下进行了机械卡堵水实验.精细解释隔夹层,优化多级火药配置及装药量,现场应用一口井,达到了射穿隔夹层沟通剩余油的目的,并有效封堵了出水层段,为塔河油田三次采油剩余油挖潜提供了思路.

In conventional perforations, drilling path often deviates from reservoirs, and drilling depth is not enough to penetrate interlayers. In view of the difficulties of remaining oil tapping, a new perforating technique with gunpowder was innovated. To seal water, mechanical water plugging experiments were made under perforating hole environments. The technique was applied in one well with the fine interpretation of interlayers and the optimization of gunpowder. The interlayers were perforated through and the remaining oils were exploited, providing a new idea for tertiary oil recovery in the Tahe Oilfield.
