多分量转换波地震勘探技术
|
摘要
多分量转换波地震勘探既具有纵波勘探深度大、资料采集相对容易和投资少的特点 ,又能反映地下介质的横波速度变化。该技术的这一特点 ,使岩石和油气的直接识别成为可能。同时 ,由于多分量的数据采集可以利用横波分裂产生的快慢横波时差 ,反映裂缝发育的主方向和发育密度 ,使得裂缝油气藏的勘探成为可能。如今 ,二者紧密相连的各向异性理论方法研究 ,已成为国内外地震勘探领域的研究热点之一 ;建立与完善多分量地震资料处理解释系统 ,是这项技术发展的当务之急。
Seismic exploration technique of multicomponent converted wave not only has many advantages of deeper prospecting depth, easier sampling and less investment for compressional wave, but also can reflect change in shear wave velocity of subsurface media. It makes direct recognition for rocks and oilgas possible. At the same time multicomponent data acquisition may make the exploration of fracture oil reservoirs possible since it can reflect the major direction and density of the fracture development using the time differences between quick and slow shear waves which resulted from the shear wave splitting. Now, anisotropy theory about the above two has become one of the focuses of study in the field of seismic exploration at home and abroad. The urgent matter of developing this technology is to build and improve processing and interpretation system of the multicomponent seismic data.
