摘要
江汉盆地江陵凹陷油气富集在长期继承性隆起构造的顶部。利用地震资料质量和速度研究围绕有利生烃向斜周缘进行原生和次生油气藏勘探取得了较好的勘探效果。经勘探表明:资福寺向斜生油量有限,纵向上受主力烃源层分布限制,一定规模的断层控制了次生油气藏纵横向分布;深层原生油气藏勘探还存在较大油气资源潜力。目前江陵凹陷油气勘探的主要方向为次生油气藏、深层油气藏和岩性油藏。
Some laws of hydrocarbons rich accumulation in Jingling Depression is that the beneficial hydrocarbons accumulation areas are in the top of the uplift structure that is the inheritable structure over a long period of time. Good exploration effects have been obtained through the researches using the quality and the speed of seismic data to develop primary and secondary hydrocarbon reservoir exploration around the beneficial generative hydrocarbon syncline. It has been proved through the exploration that:the oil-generating quantities are limited in Zifushi syncline, which vertically are subject to the hydrocarbon source bed distribution,and the certain scale fault has controlled the secondary hydrocarbon reservoirs distribution vertically and laterally; the exploration from the deeper primary hydrocarbon reservoir still exists relative large resource potential. Currently the main directions of oil and gas exploration in Jianglin Depression are secondary hydrocarbon reservoirs,deep hydrocarbon reservoirs and lithologic oil pools.
