【摘要】 孔南地区沙河街组油藏受构造和沉积储层双重因素控制。为了进一步挖掘沙河街组油气资源潜力,应用地震资料分频处理、波形聚类分析和多参数属性提取等方法开展了储层预测研究。认为孔南地区砂体平面分布呈现出以下3个特征:隆凹相间的区域背景控制砂岩沉积体系的宏观分布;断裂活动和断裂组合控制砂体的走向;构造带控制砂岩的分散体系。

【Abstract】 Petroleum pools of Shahejie Formation in the Kongnan area of Dagang oilfield are controlled by structure and depositional reservoir.In order to promote the petroleum exploration of the Shahejie Formation,we use many ways(i.e.frequency division of seismic data,cluster analysis of wave pattern,and extraction of multi-parameter seismic attribute) to predict the reservoir body.The results suggest that three features of sandstone distribution in plane would exist as follows: the interphase structures between arched and valley areas controlling the macroscopic sedimentation volume,fault activity and fracture assemblage controlling the trend of sandstone body,and structural zone controlling the disperse system of sandstone body.
