【摘要】：潭口地区属于极具盐湖盆地特色的一个大型盐隆构造,其结构构造十分复杂。近年来通过对潭口地区结构构造及演化开展再认识,认为潭口地区具有盐湖特色的S形嵌入构造。结合已有钻探资料与油气发现,首次明确提出潭口凸起同沉积断层带下降盘发育多期坡折扇体,同时指出该区存在4类重点勘探目标,即潭口凸起周缘构造油藏勘探目标,潭口凸起东、西部滩坝岩性油藏、水下分流河道构造—岩性油藏勘探目标,潭口凸起南部同沉积断层带下降盘坡折岩性油藏及嵌入型构造油藏勘探目标,高断阶带新沟嘴组、白垩系它源油藏勘探目标。
[Abstract]:Tankou area is a large salt-uplift structure with the characteristics of salt lake basin, and its structure is very complicated. In recent years, the structural structure and evolution of the Tankou area have been re-recognized, and it is considered that the Tankou area has a S-shaped embedded structure with the characteristics of salt lakes. Based on the existing drilling data and oil and gas discovery, it is proposed for the first time that there are four kinds of important exploration targets, that is, the exploration target of the structural reservoir around the Tankou uplift in the Tankou uplift synsedimentary fault zone, and that the slope folding fan body is developed in the descent plate of the Tankou uplift fault zone for the first time. Tankou uplift east, west Tanba lithologic reservoir, underwater distributary channel structure-lithologic reservoir exploration target, southern Tankou uplift southern synsedimentary fault zone downhill slope break lithologic reservoir and embedded structural reservoir exploration target, high fault zone Xingouzui formation, Cretaceous source reservoir exploration target.
