苏仁诺尔油田断层特征研究

乌尔逊凹陷一直是油气勘探的重点目标,下一步油气勘探应围绕其内七个大的断裂带进行。尤其是苏仁诺尔和巴彦塔拉两个断裂带,它们距油源区近,且具有上述对油气运聚成藏控制作用的特征。文章利用地震与地质结合的方式,建立断层圈闭系统,运用钻井、地震资料,通过地震相及断陷发育过程及成因机制研究,分析了乌尔逊凹陷苏仁诺尔断裂特征及其与油气藏形成与分布的关系及作用。研究结果表明,苏仁诺尔断裂对乌尔逊凹陷油气成藏与分布起到了极大控制作用,油气在平面上主要沿苏仁诺尔断裂分布,与断层有关的圈闭是主要封闭类型。为未来油气勘探提供依据,为海拉尔盆地油气生成和运移聚集研究提供背景资料。

Analysis on Faultage Characteristic of Surennuoer Oilfield

The Wuerxun Sag is an important oil and gas exploration target,and the exploration should be around the seven big faultage zone.Especially the two faultage zone of Surenuoer and Bayantala,which are near the source area,and have the features of the oil and gas migration and accumulation controlling.We combined the seismic and geological methods to establish the faultage trap system,by using the drilling and seismic data.The analysis on the characteristics of Wuerxun Sag Surenuoer fracture and the forming and...
