| 摘 要： | 经历多期构造运动后叠合形成的塔河西南部,用常规速度分析及成图方法都无法制作高精度的构造图,不能满足生产的需要。这里利用塔河西南部钻遇S-D的50口钻、测井资料和3D地震资料,提出了以标准层为基础的井控外推法来拟合速度并最终作构造图的方法。该方法简单实用、成本低,与实际钻探圈闭相对误差小于1.5%,能满足成图精度要求。同时,在研究过程中还发现了多个圈闭,这必将对该区油气资源的重新评价及进一步勘探有重要意义。

| Abstract: | Conventional velocity analysis and structural mapping methods can not meet needs of production.The paper presents a structural mapping method with well point control extrapolation based upon the key beds using data from drilling,well logging and seismology.The method has the characteristics of simplicity and utility,low cost and relative errors between detected traps by the method and that by drilling are less than 1.5%,and several traps have been found by the method. These results show that the method is important for reappraising and prospecting the oil-gas resources of the region. |
