徐闻地区综合地球物理勘探方法应用研究
|
摘要
徐闻地区位于北部湾盆地向雷州半岛的延伸部分,具有较好的油气勘探前景.2003年至今,江苏油田在徐闻地区先后开展了重力、大地电磁测深、二维地震和三维地震,以及钻探、VSP和试油测试等油气勘探工作.徐闻地区存在比较特殊的地表与地下地质条件.工区跨越半岛陆上和浅海水域,浅表层多套火成岩覆盖(出露),深层构造破碎、地震反射成像困难.因此,开展了具有针对性的综合地球物理方法(重力、大地电磁测深和地震)研究与勘探实践,克服了单一地球物理方法的局限性,获得了较好的数据资料,减少了多解性并为该地区的油气发现奠定基础.
The Xuwen area lies in the south of the Leizhou peninsula,which is the extending of the North Gulf basin,had been evaluated as a good prospect of oil and gas exploration foreground.Comprehensive geophysical methods(gravity survey,magnetotelluric sounding,2D and 3D seismic profiling,drilling,VSP and well testing) have been used in this region.There are many particular conditions of surface and subsurface geology when we launched geophysical jobs.such as the work area across peninsula and epeiric sea,multiperiodic eruptive rock cover or outcrop in the Xuwen area near-surface,and seismic imaging have encounterd difficulty because of deep complex structure.The comprehensive geophysical surrey has been conducted to solve these problems.
