非地震综合物探方法在油气地质调查中的应用——以松辽外围中新生代盆地群巴林左盆地为例

通过在松辽外围中新生代盆地群巴林左盆地开展的非地震综合物探剖面测量工作，利用综合重力、磁法、大地电磁测深成果，基本圈定了巴林左盆地范围、盆地基底起伏和埋藏深度，了解了不同电性层的厚度变化情况，推断了断裂构造.研究成果表明，应用非地震综合物探方法在火山岩覆盖区调查潜在沉积盆地分布、构造格架是可行的.高精度重力、磁法、大地电磁测深综合物探方法组合在油气地质调查中效果明显、方法有效.

APPLICATION OF INTEGRATIVE GEOPHYSICAL METHODS IN GEOLOGICAL SURVEY FOR OIL AND GAS:A Case Study of the Meso-Cenozoic Balinzuo Basins in the Periphery of Songliao Basin

Through the integrative geophysical profiling survey on the Meso-Cenozoic basins in the periphery of Songliao Basin,the extent to west,basement relief and burial depth of Balinzuo Basin are determined.The thickness variation of different electric layers is recognized.The fault structures are inferred.The study confirms that the application of nonseismic comprehensive geophysical methods in the investigation of structures and distribution of prospective sedimentary basins are feasible.The integration of gravity,high resolution magnetic and electromagnetic methods is rather efficient in the geological survey for oil and gas.
