摘要
新疆地区石油资源勘探开发前景广阔,准噶尔盆地南缘山前地带就是其中的重点区域。但是该地区勘探难度大,特别是准噶尔盆地南缘山前地带,砾石层大量分布,埋深厚,部分地段埋深甚至达到1 km以上,对地震勘探及其他勘探方法,带来了极大挑战。本文通过分析广域电磁法在准噶尔盆地南缘山前带砾石层的勘探应用效果,说明了电磁法在石油勘探中,也大有可为。
However,the prospect of oil resources exploration and development in Xinjiang is far beyond these achievements,and there are still large-scale reserves lying underground.The piedmont area at the south edge of Junggar Basin is one of the key areas.However,the exploration in this area is very difficult;especially in the piedmont area on the southern margin of Junggar Basin,the gravel layer is widely distributed and deeply buried,and the buried depth of some sections is even more than 1 km,which brings great challenges to seismic exploration and other exploration methods.This paper analyzes the application effect of the wide field electromagnetic method in the piedmont area on the south margin of Junggar Basin,expounds the application effect of the electromagnetic method in the exploration of shallow gravel layer and deep concealed structure,and indicates that the electromagnetic method has great potential in oil exploration.
