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
Differences of distribution characteristics of oil and gas by the control of fault-sand transporting system in uplifted area and slope area
摘要
Abstract
To better understand the law of oil and gas distribution in Liuchu and the Wen'an slope area, based on previous studies of the fault-sand transporting system and its distribution,this study focused on differences in the distribution charac-teristics 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 Wen'an 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 Wen'an 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 Wen'an 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.关键词
