渤南地区BZ28-2油田断裂在油气成藏过程中的作用
|
摘要
为了研究渤南地区BZ28-2油田油气成藏规律,在研究断裂特征、油藏类型和油气分布特征的基础上,通过解剖油藏和研究断裂与油气类型之间关系,结合油藏发育史中断裂与油气分布之间叠合关系,总结了断裂在渤南地区BZ28-2油田油气成藏过程中的作用。其作用主要表现为:油源断裂分布控制着油气平面分布的范围,油源断裂交叉处及末端是油气运移聚集的优势部位,断裂侧向封闭控制着油气富集程度和层位,成藏后断裂活动控制着油气的再分配。
In order to study the accumulating law of the oil and gas in Oilfield BZ28-2 of Bonan region, based on the research on the fault characteristic, reservoir type and hydrocarbon distribution feature, by means of the reservoir anatomy and researching on the relationship between the faults and oil-gas types, combined with the overlapped relationship between the faults and oil-gas distribution in the development history of the oil reservoir, the fault roles in the process of the oil and gas accumulation were summarized for the oilfield in the region. The roles are mainly shown as follows: the fault distribution connected the source rock controls the oil and gas distribution range on the plane, the intersect and end of the faults are the preferential places of the oil accumulation and migration, the lateral sealing of the faults dominates the hydrocarbon enriched degree and horizon, the fault activities after the accumulation control the redistribution of the oil and gas.
