从中国地质调查局油气地质调查成果交流会获悉,历经12 a,我国油气新区、新领域、新层系基础地质调查取得6大突破。一是初步证实横贯我国北方东西向天山-兴蒙构造带是新区、新层系油气勘探目标区。在银额盆地及其邻区首次发现石炭-二叠系有5套厚度大、区域分布稳定的烃源岩及其有利的油气藏赋存条件,展示良好的油气资源前景;在松辽盆地外围新发现6个中新生 According to the exchange of results of the geological survey of the China Geological Survey, it has been learned that after 12 years, six major breakthroughs have been made in the basic geological survey of China’s oil and gas areas, new areas and new strata. First, it was initially confirmed that the east-west Tianshan-Northern Mongolia Tectonic Belt is a new zone and a new layer of hydrocarbon exploration target area. For the first time in the Yinbian Basin and its adjacent areas, there are five sets of source rocks with large thickness and stable regional distribution and favorable reservoir conditions that show good prospects for oil and gas resources. In the periphery of the Songliao Basin 6 newly found middle school students
