准噶尔盆地西北缘九区八道湾组油藏物源及古流向分析

Provenence and Palaeocurrent Direction Analysis of the Oil Reservoir of Badaowan Formation of the Jiu Well Field in the Northwest Edge of the Junggar Basin

利用九区八道湾组油藏的分析化验数据,结合录井、测井和地震等资料,通过岩石碎屑组分基本数据,运用砂砾岩百分含量、古水流水动力、砂岩成分、重矿物成分进行系统分析,得出了西北哈拉阿拉特山为九区下侏罗统八道湾组的主要物源区,物源区方向总体自北西而东南至南;建立了沉积体系及沉积相模式,指导了九区八道湾组油藏滚动开发及滚动扩边部署.

By analyzing the analytical data of the oil reservoir in Badaowan Formation of the Jiu Well Field and the rock fragment components , using sadst one percentage, the power of the Palaeocurrent , sadst one content and Heavy Mineral, and also to be based on the suficiently data from well logging, driling and seismic. The direction of the Provenence from the Northwest to the Southeast and South in the research section had been studied. The Northwest of the Hala＇alate Mountains is the main Provenence section of the Badaowan Formation of Lower Jurassic in the Jiu Well Field.The system of the Sedimentary and the pattern of the Sedimentary facies had been established, all of these had guided the development and the expansion of the oil reservoir of Badaowan Formation.
