望江—潜山地区上组合油气地质条件研究及有利目标预测

望江—潜山地区目前处于油气评价的早期阶段,工作程度较低。以油气地质理论为指导,依据地表露头、地化检测、地震资料、重力航磁等资料,对研究区油气源、储盖条件等进行了分析与探讨。综合研究认为:望江—潜山地区处于南北对冲带前缘,构造位置有利,地层保存完整,上组合(主要为中生界、上古生界)成藏配置较好,具备形成油气藏的基本地质条件,具有广阔的油气勘探前景。中新生代—古生代的叠合区应是该区寻找油气藏的有利方向。

Research on hydrocarbon geologic conditions and favorable target prediction of upper hydrocarbon play in Wangjiang-Qianshan region

Wangjiang-Qianshan region is presently in the early stage of hydrocarbon evaluation with lower degree of prospecting. Guided by the petroleum geology theory and based on the data like surface exposure, geochemical analysis, seismic data and gravi-ty aeromagnetic data, conditions such as hydrocarbon, reservoirs and seals conditions and so on were analyzed and discussed. Com-prehensive studies suggest that the Wangjiang-Qianshan region located in the S-N ramp band with favorable structural situation, well preserved stratum, better accumulated collocated upper hydrocarbon play （mainly the Mesozoic and the Upper Paleozoic） has the basic geological conditions to form reservoirs and wide oil and gas exploration prospects. The overlay region of the Mesozoic-Ce-nozoic and the Paleozoic is the favorable area for oil and gas exploration.
