摘要
通过对柯克亚含气碳酸盐岩波阻抗及界面反射系数的研究,取得了柯克亚深部E2k气藏暗点存在的地震地质依据。在准确标定层位的基础上,借助计算机彩色显示技术,成功地进行了暗点识别,确定了气水界面及含气面积。
The seismic and geologic proof is concluded in this article,which can explain the dim spot existed at the deep Kekeya's E 2 k gas reservoir,from studying the acoustic impedance and the surface reflection coefficient of Kekeya gas-bearing carbonate rock.On the basis of correct layer defined,and by means of color display in the computer,the dim spot is successfully identified and the border of gas and water as well as area of gas containing is finally confirmed.
