摘要:

黄河口凹陷位于渤海海域的东南部,郯庐断裂带西支从凹陷中央穿过,并在此分成了东西两支,形成了中央隆起区走滑转换带,从目前勘探成果来看该走滑转换带成为黄河口凹陷主要含油气构造带之一.通过对该走滑转换带构造与演化特征的研究,以及对转换带内油气成藏特点的分析,指出转换带通过控制圈闭的发育、砂体的展布和油气的运移疏导体系的形成,控制了凹陷内中央隆起区的油气聚集.研究转换带对油气聚集的控制作用,有利于寻找油气富集区,提高勘探效率.

Abstract:

The Huanghekou sag,located in the southeast of Bohai Sea waters,is cut through at the center by the west branch of the Tanlu fault zone,forming a strike-slip transform belt in the central uplift.This belt,according to recent exploration results,is considered as one of the key hydrocarbon-bearing structural zones in the sag.Studies on the structures and their evolutionary characteristics in the belt,in addition to the analysis of the hydrocarbon accumulation patterns inside the belt,indicate that the transformation belt controls hydrocarbon accumulation in the central uplift through controlling the development of traps,the distribution of sandbodies,and the formation of carrier systems.The controlling effect of the transform belt is therefore regarded as a useful clue for finding hydrocarbon-bearing areas and for improving exploration efficiency.

Key words: strike-slip transform belt, hydrocarbon accumulation, Tan-lu fault zone, Huanghekou sag, Bohai Sea waters
