MQZ地区位于渤海湾盆地辽河坳陷西部凹陷,其南部为受坡折带控制的缓坡带,是各类水下扇体发育的有利地带。坡折带下的低位扇由于离源岩近、次生裂隙发育和疏导条件优越,易形成岩性油藏。通过对MQZ地区岩性油藏的勘探实践,总结出进行岩性油藏勘探的三要素:高分辨率地震资料是寻找岩性圈闭的基础,层序地层学是寻找岩性圈闭的理论指导,地震储层预测技术是寻找岩性圈闭的手段。

MQZ region is situated in the western sag of the Liaohe Depression in the Bohai Bay Basin.The ramp zone controlled by slope break is favorable for underwater fans generation.Since they are near source rock and have good reservoir beds and channels,the low-system-type fans can form lithologic oil pools.By exploring lithologic traps in MQZ area,it is concluded in this paper the 3 ways to explore lithologic traps.High resolution seismic data are the base of lithologic trap exploration,sequences stratigraphy is the theory, and seismic prediction technology is the method.
