内蒙古突泉盆地侏罗系油气发现及工作展望

DISCOVERY AND PROSPECTS OF THE JURASSIC OIL AND GAS IN TUQUAN BASIN, INNER MONGOLIA

摘要: 突泉盆地是公益性油气基础地质调查项目在大兴安岭中南部火山岩覆盖区已发现的油气新区，有望成为实现松辽外围侏罗系油气新区、新层系勘探突破的远景盆地.基于突泉盆地地质背景、沉积特征与烃源岩发育特征，阐述了突参1井和突D1井的地质设计思路及其油气发现情况，并从原型盆地恢复、烃源岩评价、火山岩覆盖区勘探方法以及非常规致密油的超低孔、超低渗储层等方面，对下一步工作进行了探讨.

Abstract: Tuquan Basin, located in the mid-south of Daxinganling region, covered by volcanic rocks, was recognized as a new area for oil and gas exploration by the program of fundamental geological survey for energy resources. This basin will promisingly achieve a breakthrough for oil and gas exploration in new Jurassic horizons and areas in the periphery of Songliao Basin. Based on the analysis of geological background and sedimentary characters about the source rocks, the designing ideas of the TC1 and TD1 drill holes and the discovery of crude oil are expounded. Moreover, the paper also discusses the prototype restoration of basin, assessment of source rocks, exploration methods in volcanic rock-covered areas, as well as the analysis of ultralow porosity and permeability reservoir related to the unconventional tight oil.
