摘要
近年来,中国老油田开发逐渐进入中后期,油气对外依存度也持续增高,亟需寻找新的油气区接替。三江盆地位于中国东北黑龙江省东部,是松辽盆地外围东部面积最大的盆地,迄今暂未取得油气勘探突破。笔者通过对三江盆地开展野外地质调查和钻井勘探,分析总结了该区早中生代沉积的大架山组含硅质岩层系的岩性与分布特征,认为这套早中生代硅质岩与暗色泥岩地层在盆地东部广泛发育并且厚度较大,并且相关测试结果表明其中的暗色泥岩有机质丰度可达0.95%,有机质类型以Ⅱ1型为主,处于高成熟阶段,具有良好的生烃潜力,有望成为三江盆地油气勘探新层系,值得进一步开展油气勘探工作。
The development of oil field has entered the middle or late stage, and the dependence of oil and gas resources on imports is gradually increasing;therefore, the search for new oil and gas areas is an urgent task. Sanjiang Basin, which is located in the east of Heilongjiang Province, is the largest basin in the eastern periphery of Songliao Basin, but there has been no breakthrough in oil and gas exploration there. Through field geological survey and drilling exploration in Sanjiang Basin, the authors summarized the lithological and distribution characteristics of siliceous rock series of Dajiashan Formation deposited in early Mesozoic in this area.The siliceous rocks and dark mudstone strata are widely developed in the eastern part of the basin and has a large thickness, with total organic carbon abundance up to 0.95%;Ⅱ1 is the main organic matter type and is developed at the high maturation stage, and hence it is expected to become a new layer of oil and gas exploration in the Sanjiang Basin.
