摘要
利用完钻井声波时差资料,计算出高升探区地下流体压力及剩余压力分布,并对异常地层压力的成因进行探讨。结合构造、沉积等条件分析,探讨该区油气运移方向,寻找有利油气聚集地区。研究结果表明,油气分布受油气运移带控制;牛心坨地区存在一条北东向的油气运移带,曙北-雷家地区存在多条油气运移带,对油气运移起重要的作用。
Formation fluid pressure and residual pressure distribution in Gaosheng exploration area are estimated by using acoustic slowness data of completed wells. The genesis of abnormal pressure is also discussed in this paper. Combining with analysis of structure and sedimentation , oil and gas migration direction is studied to find favorable oil and gas accumulations in (his area. The result of the study shows that, oil and gas distribution was controlled by oil and gas migration; there was a NE migration zone in Niuxintuo area and there were several migration zones in Shubei - Leijia area.
