通过岩心化验、测井资料及生产动态等资料,绘制长6各小层的有效砂体厚度等值线图、沉积相图及油气平面分布图和油藏剖面,对杏子川油田郝84井区长6层段沉积特征、油藏类型、油气分布特征及其控制因素进行综合分析研究。研究表明:郝84井区长6储层为三角洲前缘沉积,水下分流河道和河口坝发育,长6油藏为岩性油藏,主要受岩性控制,石油沿有效砂体呈条带状北东向展布,主要富集在水下分流河道及河口坝砂体中。
The contour maps of sedimentary facies, sedimentary facies, oil and gas distribution maps and reservoir profiles were drawn from core samples, well logging data and production data. The sedimentary characteristics, reservoir types, oil and gas distribution characteristics and their controlling factors in the long 6th layer are comprehensively analyzed and studied. The results show that the reservoir of Chang 6 in Well No.84 is characterized by delta front deposition, underwater distributary channel and estuarine dam. Chang 6 reservoir is a lithologic reservoir mainly controlled by lithology, with oil along the effective sand body Shaped north-east distribution, mainly concentrated in the underwater distributary channel and estuary bar sand body.
