摘要
形成箕状凹陷的控制断层控制了凹陷陡翼的构造地质、石油地质特征。凹陷的沉降、沉积中心位于控制断层附近,形成了丰富的油源;控制断层的继承性构造运动及其时空差异,造就了箕状凹陷陡翼形式多样的圈闭类型。二者的有机配合,在箕状凹陷陡翼聚集了丰富的油气资源,形成了多种类型的油气藏,是石油勘探的重要场所。
The major fault which created a half graben-like basin controls the features of both structural geology and petroleum geology at the steep side of the half graben-like basin. The sedimentation and subsidence centers of the half graben-like basin are all close to the major fault,near which rich oil source was generated. The nonuniform growth of the major fault resulted in various traps at the steep side, thus forming abudant hydrocarbon resource, or more correctly multitudinous oil accumulations at the steep side. So the steep side is an important place for oil exploration.
