摘要: 地层压力大多利用层速度来进行预测。在准中董2井北三维区,利用叠加速度资料通过Dix公式建立了初始的层速度场,然后用声波测井速度对初始层速度场进行了校正,得到了精度更高的层速度场。利用Eaton法进行了工区的三维地层压力预测,预测结果表明,研究区异常高压顶界面基本位于头屯河组底部,头屯河组及其以上地层基本为正常压力,头屯河组局部发育异常高压,西山窑组、三工河组、八道湾组为异常高压段。结合测井压力检测、实测地层压力和研究区地质特征进行分析,表明最终压力预测结果是合理的。

Abstract: The formation pressure is mostly predicted by the interval velocity. In 3D area of Northern Block Well Dong 2, central Junggar Basin, the original interval velocity field was established by the stack-ing velocity data through Dix formula, and then corrected the original interval velocity field by using sonic logging velocity, the more accurate interval velocity field was obtained. The 3D formation pressure of work area was predicted by using the Eaton method, the prediction result indicated that the top interface of abnormal overpressure in study area was basically located at the bottom interface of Toutunhe Formation, the pressures of Toutunhe Formation and its overlying layers were normal, only part of Toutunhe Formation developed the abnormal overpressure, Xishanyao Formation, Sangonghe Formation and Badaowan Formation were abnormal overpressure intervals. The final pressure prediction result was reasonable after it was analyzed by logging pressure detecting, measured formation pressure and the geological characteristics of the study area.
