一九七五年冀中拗陷于震旦亚界雾迷山组,高于庄组碳酸盐岩地层中喷出高产油流,首次在我国最古老的沉积岩中发现了任丘吉潜山高产大油田,在这样古老的地层中喷出高产油流,国内外都是少见的,这一突破,打开了找油的新领域,给石油地质理论提出了新的课题。 今年三所石油学院在燕山地区开展了找油会战,通过近一年的室内外工作,就燕山西段 In 1975, the Jizhong depression was trapped in the Wumishan Formation in the Sinian sub-region, and the high-yield oil flow was emitted from the carbonate rocks in the Gaozhuangzhuang Formation. For the first time, the Renqiuzi buried hill high-yielding large oilfield was discovered in the oldest sedimentary rock in China It is rare at home and abroad that this high-yield oil flow is spurting out in such ancient formations. This breakthrough opened up new areas for oil exploration and put forward new issues for the theory of petroleum geology. This year three oil institutes in Yanshan area to carry out the oil battle, through nearly a year of indoor and outdoor work, on the western section of the Yanshan
