【摘要】 多波多分量地震勘探技术经历了横波勘探-纵横波联合勘探-转换波3D3C地震勘探的发展历程。目前在海上和陆上实施最多的多波多分量地震勘探方法是转换波三维三分量(3D3C)地震勘探方法。转换波3D3C地震勘探具有很多优势,利用转换波3D3C地震勘探技术能够解决复杂气藏地质问题中的砂泥岩储层预测、裂缝检测及流体性质识别等问题。从目前取得的成果来看,该勘探方法的良好,但需要解决的问题也比较多,比如转换波预测裂缝方位的不确定性、纵横波联合的流体性质识别、转换波深度域成像等问题。因此,转换波3D3C技术的完善、资料处理能力的提高、解释技术的发展都是多波多分量勘探技术向工业界推广过程中必须解决的问题。回顾了多波多分量技术的发展历程,提出了目前转换波3D3C技术中存在的问题,并分析了转换波3D3C勘探技术的发展趋势。更多还原

【Abstract】 Multicomponent seismic prospecting technology was developed from shear wave exploration to joint exploration of compressed and shear waves,then to converted wave 3D3C seismic technologies.At present,converted wave 3D3C seismic prospecting was the most popular technology in oil and gas exploration for its superiorities to solve the complex problems in reservoir prediction,fracture detection and fluid property identification.Seeing from the achievements on research of Multicomponent seismic prospecting technologies,there still existed many problems.It’s necessary to perfect the converted wave 3D3C seismic technologies,improve the data processing ability,introduce the data interpretation for extending C wave 3D3C seismic technologies for industrial application widely.The development of multicomponent seismic prospecting technology is reviewed,the problems are outlined and the development of converted wave 3D3C seismic technologies is analyzed.更多还原
