Dc指数随钻监测地层压力的应用分析
|
摘要
利用在线辅助决策系统的实时参数数据库及压力预测软件drillworks,结合综合录井方法及Dc指数法,跟踪了A井、B井和C井三口井的地层压力情况。在线辅助决策系统的软件系统,可显示钻井过程中的各种参数,对定性判断是否进入异常高压地层,起着很重要的作用。地层压力监测的结果显示,使用Dc指数法跟踪监测该地区地层压力,具有较高的精确性。
Using real-time parameter database of online assistant decision-making system and pressure prediction software drillworks, combined with the comprehensive logging method and Dc index method, the formation pressure of the wells A, B and C has been monitored. Various parameters in the process of drilling can be display throughonline assistant decision system, which plays a very important role for qualitative judgment of whether entering the abnormal high pressure formation. Formation pressure monitoring results indicated thatthe formation pressuremonitoring accuracy is high using Dc index method.
