通过对济阳坳陷东营凹陷北部陡坡构造带地层对比、地震资料和合成记录标定,详细划分了沙四段地层,确定了太古界的反射界面,证实本井自沙四上纯下亚段进入太古界地层。通过对永937井及邻近几口井成藏条件的分析,总结了该区的成藏控制因素,认为该区油气成藏主要受沉积相带控制,其次储层发育情况和储层物性、构造位置高低也是油气成藏的重要控制因素。
By comparing the stratigraphy of the steep slope structural belt in the northern part of Dongying Sag, Jiyang Depression with seismic data and synthetic records, the strata of Shahejie Formation were divided in detail and the reflection interface of Archean was confirmed. Archean strata. Based on the analysis of reservoir forming conditions in Yong 937 well and its adjacent wells, the accumulation controlling factors in this area are summarized. The hydrocarbon accumulation in this area is mainly controlled by sedimentary facies, followed by reservoir development and reservoir physical properties, structure Location is also an important controlling factor for oil and gas accumulation.
