海拉尔盆地乌东斜坡带南一段油水分布规律研究

Research on oil-water distribution k1n1 in the slope belt of Wudong,Hailaer basin

本文通过对乌东斜坡带上的探井及开发井的试油、射孔、测井等资料的研究,对该带主力产油层位南一段的油水分布有了系统的了解。通过对油水分布起控制因素的断裂和砂体匹配关系的分析,得到了两条规律性的认识,即纵向上由北往南含油层位逐渐变深;平面上,自北而南含油性呈现"好-差-好-差"的规律。因此,搞清楚油水分布对进一步的开发部署有重要的指导意义。

By research on testing oil,perforating,logging data of test wells and development wells in the slope of Wudong,understanding of the oil-water distribution in the main producing reservoirs k1n1.Through analysis of the relationship of fault and sand body matching,which factors control of the oil-water distribution,has been two systematic understanding,namely,vertically,oil-bearing strata gradually become darker from north to south;plane,oil-bearing showing ＂good-bad-good-bad ＂rule from north to south.Therefore,clearly oil-water distribution have important guiding significance to the further development and deployment.
