<title>me-space matching relation of source rock, caprock and faults and its controlling effect on oil and gas reservoir forming in fault basin.

源岩、盖层和断裂是断陷盆地油气成藏的主控因素,通过源岩、盖层和断裂时空匹配关系分析,对其在油气成藏与分布中的作用进行了研究,得到源盖分布空间匹配关系控制着油气聚集规模,盖层质量空间匹配关系控制着油气分布范围,较好源盖匹配关系区内断裂分布控制着油气分布的具体部位。源盖时间匹配关系控制油气的可供运移量,断源时间匹配关系控制油气的可供聚集量,断盖时间匹配关系控制油气的聚集与保存量。

<abstract>urce rocks, caprocks and faults are the main factors controlling the oil and gas reservoir forming in fault basin. By analyzing the time-space matching relation of the source rocks, caprocks and faults, its' effects on oil-gas reservoir forming and distribution were studied. Space matching relation between source rocks and cap rocks controls the oil-gas accumulation scale and oil-gas distribution scope. Distribution of the faults in area with better matching relation of source rocks and cap rocks controls the specific place of oil-gas distribution. Time matching relation between caprocks and source rocks controls the available oil - gas migration amount, the time matching relation between source rocks and faults controls the available oil-gas accumulation amount, and the time matching relation between faults and caprocks controls the oil-gas accumulation and preservation amount.
