【摘要】 <正> 在燕山台褶带的冀北坳陷的震旦亚代地层中,已发现了多处油苗和沥青;辽西坳陷也发现雾迷山第七段的泥质白云岩中有原生液态油苗。在这样古老的层系中,原生油苗的出现引起人们的重视,并进行了钻探工作。 本文根据古地温的研究,说明震旦亚界中原生油苗存在的可能性,并进一步探讨震旦亚界原生油气藏的可能形成条件和有利的分布地区。更多还原

【Abstract】 The occurrence of primary oil seepage in Sinian Sub-erathem in North China is investigated with respect to paleotemperature evolution. Paleotem-perature maps illustrating temperature evolution are constructed based on preliminary drilling and geological data. Forecasts of promising hydrocarbon bearing zones in Sinian Sub-erathem are suggested.更多还原
