隆起区和斜坡区断-砂输导体系控制油气分布特征的差异性
|
摘要
为了研究留楚地区和文安斜坡区油气分布规律,在其断-砂输导体系构成及其分布特征研究的基础上,通过油气分布与断-砂输导体系分布之间关系分析,对留楚地区和文安斜坡区断-砂输导体系控制油气分布特征的差异性进行研究。结果表明:油气纵向分布层位不同,留楚地区断-砂输导体系可向多层砂体中侧向分流运移,造成同一部位油气多层分布,而文安斜坡区断-砂输导体系主要沿一层砂体侧向输导油气,造成同一部位油气仅在一层分布;油气平面分布区域不同,留楚地区油气主要分布在有利和较有利断-砂输导体系处或附近的背斜核部,而文安斜坡区油气主要分布在油气侧向运移路径上的断层圈闭内;油气在断裂密集带分布部位不同,留楚地区断-砂输导体系分布在断裂密集带内,油气聚集分布在断裂密集带内,而文安斜坡区断-砂输导体系横穿断裂密集带,油气聚集分布在断裂密集带及边部。
To better understand the law of oil and gas distribution in Liuchu and the Wenan slope area,based on previous studies of the fault-sand transporting system and its distribution,this study focused on differences in the distribution characteristics of oil and gas controlled by the fault-sand transporting system. The relationship of oil-gas distribution and fault-sand transporting system was analyzed. The result shows that the location in the vertical distribution of oil and gas is different. The fault-sand transport system in Liuchu area can migrate laterally to multisand body,which leads to multi-layer distribution of oil and gas. The fault-sand transport system in the Wenan slope area mainly transports oil and gas laterally along the same layer of sand body,which causes only one layer distribution of oil and gas. Laterally the distribution of oil-gas is different.The distribution of oil-gas in Liuchu area is mainly in the favorable to relatively favorable fault-sand transporting system,or the surrounding anticlinal nucleus,while the distribution of oil-gas in the Wenan slope area favors mainly the fault trap in the lateral migration path of oil and gas. The distribution of oil and gas is also different in concentrated fault zones. In Liuchu area the fault-sand transporting system is distributed in concentrated fault zone with oil and gas distributed within it. In the Wenan slope area,however,the fault-sand transporting system is distributed across the concentrated fault zones with oil and gas accumulated in the concentrated fault zone and the edges.
