马2断块油藏形成的控制因素及勘探建议

通过对马2断块地层沉积相、构造及油藏类型的分析介绍,参考马2断块油藏储层基本特征、油藏开发动态、油气显示和数值模拟最新研究结果,根据马2断块区域石油地质条件,对马2断块油藏形成的控制因素进行了深入分析、研究,明确提出“储集沙体及断裂系统的发育和断裂性质是该区块油藏形成的主要控制因素”的观点。并结合剩余油分布特点,提出了进一步勘探的建议,为马2断块油藏的挖潜和勘探目标的选择指明了方向。

CONTROLLING FACTORS OF FORMATION OF MA-2 FAULT BLOCK OIL RESERVOIR AND SUGGESTIONS FOR EXPLORATION

Based on analyzing the sedimentary faces, structures andoil reservoir types and referencing to the characters of reservoirrocks, dynamic feature of development and the result of numeri-cal simulation of Ma-2 fault block oil reservoir, the controlling factors of oil reservoir forming have been studied in this paper and the point of view is definitely brought forward, which is that reservoir sands, fault fracture system development and characters of fault age are the min controlling factors of oilreservoir forming. In conclusion, the next suggestions for ex-ploration of Ma-2 fault block oil reservoir is pointed out by com-bining the controlling factors of oil reservoir forming with the distribution of remaining oil of Ma-2 fault block oil reservoir.
