碳酸盐岩地层裂缝非常发育,使得地层具有强烈的各向异性.地震波传播时,其振幅、走时、速度、频率、吸收等具有明显方位特性.它们的变化是和裂缝的方向和强度密切相关的,因此可利用纵波方向特性来进行裂缝预测.研究了利用方位层间旅行时来预测裂缝的方法,并预测了塔北一轮古东区碳酸盐岩的裂缝发育情况,取得了较好的效果.

The well developed fractures in carbonate rocks allow the strata to be of strong anisotropy which causes obvious orientation in seismic wave propagation such as amplitude, travel-time, interval velocity, frequency and absorption, etc. Their variations are closely related to the fractural orientation and density, hence the fractural prediction can be conducted using P-wave orientation characteristics. This paper studies the method for fractural prediction by using orientation and interval travel-time, by which the fracture development situation of carbonate rocks in Tabei-Eastern Lungu area in Tarim basin is predicted and good effectiveness or results are obtained.
