斜坡油气勘探

箕状凹陷是一种广为发育的盆地类型,它往往构成一个独立的油气勘探对象。斜坡是箕状凹陷的主要构造单元,也是油气区域运移的主要指向和主要成藏地带。但相对而言,斜坡的油气勘探较箕较凹陷中的中央隆起带等其他构造单元的油气勘探难度更大,是一个有待进一步加强勘探的领域。本文根据我国东部广泛发育的箕状凹陷的地震、地质实际资料,对斜坡进行了分类,提出了“两类十种”的分类方案,对其石油地质特征,评价和勘探思路进行了讨论,以期有助于斜坡油气勘探的深入发展。

Oil-gas exploration on slope.

Half graben is a widely developing basin type and often constitutes a independent object for oil gas exploration. The slope is major structural unit of half graben and also is main direction for regional oil gas migration and main oil gas accumulation zone. But comparatively speaking, the oil gas exploration on slope is more difficult by comparison with in central uplift and in other units, so that is an area needs to further strengthen exploration. According to seismic data and other real geological data in half graben widely developed in our east area, the paper categorized the slope and put forward a category plan, that is " two categories and ten types ", and had a discussion on its petroleum geologic properties, appreciation and exploration thinking, which is in hopes of an aid to deep development of oil gas exploration on slope.
