摘要
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。
Based on comparison of stratum and seismic analysis on the steep slope in the north of Dongying Sag in Jiyang Depression, the stratum of Sha-4 zone was divided, the reflection interface of Archean Group was identified, and it＇s confirmed that the well entered the strata of Archean Group at Shangchunxiaya of Sha-4. Based on the analysis of reservoir forming conditions in 937 well and neighboring other wells, main controlling factors of hydrocarbon accumulation were summarized. It＇s pointed out that hydrocarbon accumulation was mainly controlled by sedimentary facies. In addition, the development of reservoir, reservoir physical properties and structural location were also the important controlling factors of hydrocarbon accumulation.
