地震储层预测技术在X地区砂岩薄储层中的应用

Application of Seismic Reservoir Prediction Techniquesto Thin Reservoir in the X Area

摘要: 鄂尔多斯东缘X地区致密砂岩储层较薄，横向变化较快，储层预测难度较大。运用以地质统计学反演为核心的地震储层综合预测技术来精细刻画储层分布特征，得到纵向上砂体特征刻画较清楚、平面上符合地质规律的预测成果。经过新钻井校验，综合解释符合率达90%以上，实现了薄储层的高精度预测，提高了预测精度。

Abstract: The tight sandstone reservoir in the X area on the eastern margin of Ordos is thinner, and the lateral changes are rapid, making reservoir prediction difficult. Using geostatistical inversion as the core seismic reservoir prediction technology to finely describe the reservoir distribution characteristics, obtain the prediction results that the sand body characteristics are clearly depicted in the vertical direction and conformed to the geological law in the plane. After the new drilling check, the comprehensive interpretation coincidence rate reached more than 90%, the high-precision prediction of thin reservoirs was realized, and the prediction accuracy was improved.
