摘　　要：在松辽盆地外围三维地质调查中,通过采用重、磁、电剖面探测方法对火山岩覆盖区的扎鲁特盆地进行了深部探测,获得高精度测量数据.结合地质、地震、钻探及岩石物性测试结果,对研究区深部地质体进行了综合解释.围绕油气资源调查目的层二叠系林西组,开展了密度、磁性、电性特征研究,对二叠系林西组界面起伏进行半定量、定量描述,有效刻画了目的层的空间展布,为油气资源勘查评价提供了必要的基础资料.In the 3D deep geological survey in the periphery of Songliao Basin, the magnetic, gravity, magnetotelluric and seismic methods are employed to explore the Jarud Basin with igneous cover. With integration of geological and drilling data and physical properties of rocks, the subsurface geology is inferred comprehensively. The density, magnetic and electrical features are studied for the Permian Linxi Formation, which is the target formation of hydrocarbon resources survey. The surfing interfaces and distributions of the formation are characterized half-quantitatively or quantitatively, which provides essential fundamental data for the evaluation of hydrocarbon resources.
