摘要
WP区长8段是鄂尔多斯盆地姬塬地区勘探,开发的重点地区以及层系之一。对长82小层进行研究,通过岩心描述和测井资料分析,认为该油层组为长石质岩屑砂岩。并确定在长82期WP地区为曲流河三角洲前缘亚相沉积,在平面上沉积微相主要为水下分流河道、分流间湾和河道侧翼等,其中水下分流河道微相相对发育。通过分析沉积微相与储层物性之间的关系,认为水下分流河道是有利的沉积微相。
WP Mayor paragraph 8 Jiyuan area of Ordos Basin in key areas of exploration, development, and one of the strata. 8_2 layer, core description and well log data analysis that the reservoir group for the long - lithic sandstone. And to determine the 8_2 long WP region meandering river delta front facies sedimentary mierofacies plane for underwater distributary channel interdistributary bay and river flank, including underwater distributary channel microfacies relative developmental. Through analysis of sedimentary MICROFACIES the relationship between reservoir properties, underwater distributary channel is favorable sedimentary microfacies.
