    New areas and series of strata on the periphery of Songliao Basin: the progress and recognition based on foundational geological survey for oil and gas resources

    • 摘要: 以“开辟新区、探索新层系”为目的,基于野外地质调查、非震物探剖面测量、地质井钻探等油气基础地质调查,阐述了松辽盆地外围大面积火山岩覆盖区龙江、突泉、扎鲁特、林西、乌兰盖等油气新区的发育状况及中、下侏罗统和上二叠统等主要生烃层系的发育;认为突泉盆地中、下侏罗统泥岩厚度大、有机质丰度高、热演化处于成熟—高成熟阶段,盆地生、储、盖系列完整,有望成为松辽盆地外围侏罗统油气、新层系勘探突破的远景盆地。依据暗色泥页岩分布范围、沉积厚度和有机地球化学特征,论述了研究区晚二叠世林西组的页岩气资源前景。松辽盆地西缘地区的中、下侏罗统和上二叠统将成为油气新区、新层系调查研究的重要方向。

       

      Abstract: In order to explore new areas and target strata of oil and gas resources, the authors delineated five potential Mesozoic basins covered with volcanic rocks, i.e., Longjiang, Tuquan, Zhalut, Linxi and Wulangai as new areas on the periphery of Songliao Basin, based on field mapping, outcrop profile, geo-physical survey and geological drilling. Geological characteristics of the new areas and associated new strata were described. Tuquan basin, characterized by an integrated system of source-reservoir-cap, great thickness of mudstones of the Middle and Low Jurassic, rich organic matter content and proper thermal evolution, is expected to be a new Jurassic prospective area with new stratigraphic exploration breakthrough on the periphery of Songliao Basin. The perspective of shale gas resources associated with the Upper Permian Linxi Formation is expounded in this paper in the aspects of the distribution, accumulation thickness and biogeochemical characteristics of the dark argillutite. The western part of Songliao Basin associated with the Middle and Low Jurassic, the Upper Permian, possess of huge potential in the oil and gas exploration.
