摘要：

黄河口凹陷是渤海湾盆地的一富烃凹陷,受新构造运动影响浅层断层异常发育。利用大量的油气勘探资料对凹陷内油气聚集成藏影响因素分析认为,这些新构造运动形成的断层对浅层油气聚集起到重要的控制作用。通过对断层组合类型及其控制下的油气藏分析,最终归纳出3种不同类型的断层组合及相应的富集成藏模式,并进一步明确指出在这3类断层组合构造中针对油气富集块(区)的勘探首选目标所在:"X"型断层组合形成的垒块油藏具有油气聚集井段长,油气藏规模较大的特点,是勘探的首选目标;"包心菜式"断层组合花心部位和内花瓣部位具有较优越的成藏条件,是该类断层组合带内的优选钻探部位;"Y"型断层组合在靠近主断层的构造高部位油气藏丰度较高,是勘探的首选。

Abstract:

As one of the petroliferous sags of Bohai Bay Basin,Huanghekou sag is abundant in shallow faults resulted from neotectonic movement.An analysis of the factors controlling hydrocarbon accumulation in the sag based on the abundant exploration data shows that these shallow faults play a key role in controlling hydrocarbon accumulation in the shallow reservoirs.Through the study on the fault combinations and the reservoirs under their control,we recognized three types of fault combinations and the corresponding hydrocarbon accumulation models.Moreover,we also identified the primary exploration targets for these fault combinations.For the ‘X’-type fault combination,fault block reservoirs featuring in long hydrocarbon-bearing interval and large scale are the primary targets.For the ‘cabbage’-type fault combination,the core and inner fault blocks are the primary targets.For the ‘Y’-type fault combination,the structural high near the main fault usually are the primary targets.

Key words: fault combination, hydrocarbon accumulation, shallow reservoir, Tanlu fault, Huanghekou Sag, Bohai Bay Basin
