渤海圈闭资源量评价

用地质类比法预测渤海矿区内已发现圈闭的总资源量为31亿～35亿t,除去已找到的12亿t油气地质储量,起码还有19亿～23亿t资源量有待发现.渤海油气勘探有良好的前景,这取决于已有勘探领域的扩大和新领域的开拓.凸起区披覆背斜构造和凹陷内浅层断裂背斜构造是寻找大、中型油气藏的重要领域.

TRAP RESERVE EVALUATION IN BOHAI BAY BASIN

It is estimated that total hydrocarbon resource in discovered traps is ranged from 3. 1 to 3. 5 billion tons by means of geological analogy. At least 1. 9 to 2. 3 billion tons of hydrocarbon is awaiting to be discovered besides the 1.2 billion tons oil reserve we have found. The prospect of hydrocarbon exploration in Bohai is much better as long as we continue to explore the konwn exploration realm further and probe the unknown realm. More attention should be paid in the exploration of drape anticlines on uplift and shallower faulted anticlines in sag because these anticlines are the best prospects to discover oil fields with large and middle size.
