通过对东营凹陷中带西段沙二段区域地质特征的研究,详细分析了区域构造特征以及区域地层的分布规律,显示出两条主要断层的控制作用,以及古地貌对沉积地层厚度的控制作用。进而详细分析东营凹陷中带西段沙二段储层分布规律,并结合相应的生产井信息,分析了有利储层的分布特征;通过对生产井产油情况与处于沉积环境的对比分析出东营凹陷中带西段沙二段油气成藏的有利位置,为进一步开展勘探打下基础。
Based on the study of the geologic characteristics of the second member of Shahejie Formation in the west section of the Central Belt of Dongying Depression, the regional tectonic characteristics and the distribution of regional stratigraphy are analyzed in detail. The control of the two main faults and the control of the paleogeomorphology on the thickness of the sedimentary strata are shown . Then the distribution of the reservoir in the second member of Shahejie of the western section of the Central Belt of Dongying Depression is analyzed in detail. Based on the information of the corresponding production wells, the distribution characteristics of the favorable reservoirs are analyzed. By comparing the oil production in the production well with the sedimentary environment, The favorable position of hydrocarbon accumulation in the second member of Shahejie Formation in the western part of the sag lays a foundation for further exploration.
