太康隆起构造演化史与勘探远景

TECTONIC EVOLUTION AND PETROLEUM EXPLORATION PROSPECTIVE OF TAIKANG UPLIFT

大康隆起是北西西向展布的宽缓复式背斜，叠加有北北东向短轴褶皱，被北西西向、北东向和北北东向断裂切割。太康地区古生代至三叠纪接受了海相、海陆过渡相和陆相盆地沉积，三叠纪末隆起，地层广遭剥蚀。大康隆起的构造演化对南华北盆地的石油地质条件有重要影响。人康地区发育有两套古生界生油气层系，构成自生自储式成油组合，油气远景的关键是保存条件。该地区砖楼凹陷和通许凸起的油气勘探远景较好。

uplift is a wide and gentle anticlinorium trending NNE and superimposed by brachyfolds, which was cut by NWW, NE, and NNE fault systems. During Palaeozoic era and Triassic period, Taikang area received marine, continental-marine transition, and continental sediments, then uplifted in the end of Triassic and was denuded widely. its tectonic evolution strongly affected on the petroleum geological features within the southern North China basin. At present time, Taikang uplift area contains two sets of Palaeozoic hydrocarbon-generation strata sysems, and Zhuanlou sag and Tongxu high have better prospective for finding oil.
