摘　　要：在冀中坳陷内冀门1井所钻石门桥断块尚未试油,相继在辛中驿断块上钻探任4井,于1975年发现了任丘古潜山油田,这是我国最大的海相碳酸盐岩高产潜山油田。该油田为一复式油气聚集带,由蓟县系雾迷山组、寒武系腐君山组、奥陶系马家沟组和亮甲山组3个古潜山油藏及古潜山上覆的古近系沙河街组和东营组油藏构成,从而开创了"新生古储"潜山成藏理论,为潜山油气藏勘探开发奠定了实践和理论基础。继任丘古潜山油田发现后,在不到十年时间相继又发现10个潜山油气田,而后由于物探深层资料精度不够高,该区的潜山勘探处于停滞状态达20余年之久。任丘古潜山油田发现36 a之后,由于华北油田主管勘探领导的重视和深层物探资料的提高,牛东1井深潜山油气田才被发现。After the suecessful well testing of Well Jimen 1 drilled in Shimenqian Block and Well Ren 4 drilled in Xinzhongyi Block, Renqiu Oilfield was fnund in 1975. It is one of the largest marine carbonate buried hills with high production in China. This oilfield is a complex buried hill hydrucabon accumulation belt and is composed of tinge buried hill reservoirs including Wnmishan Formation （Jixian System）, Fujunshan Fornmtion （Cambrian）, Majiagou and Liangjiashan Formatiun （Ordovician） and Palaeogene rcservuiirs including Shahejie Formation and l）ongying Formation developed in the drape traps above the buried hill. The hydrocarbnn accumulation theory of oil generated in younger strata but accunmlated in older buried hill reservoirs is built up, which lays the foundation of theory and practice for the exploration and development of buried hill reservoirs. Following the discovery of Renqiu buried hill oilfield, in Less than ten years, 10 buried hill oil anti gas fiehts have been found. And then, because the accuracy of deep geophysical data is not high, the buried hill exploration in this area has stagnated for inure than 20 years. After the discovery of Renqiu Oilfieht for 36 years, with the improvement of deep geophysical data, Well Niudong 1 deep buried hill oil and gas fieht is found.
