层状各向同性多孔介质中井间地震的数值计算
THE CALCULATION OF CROSS-WELL SEISMIC IN ISOTROPIC POROUS LAYERED MEDIA
【摘要】 依据Biot理论,提出计算理论地震图的相应传播矩阵算法,并针对井间地震震源和检波器的不同配置进行数值计算,结果表明,本文算法高频可达1000H2以上.文中算例说明利用震源和检波器相对于储油层的不同位置,可从反射震相记录波形上的差异,判定储油层存在与否.
【Abstract】 In this paper, based on the generalized Boit’s Theory, we propose the corresponding propagaion matrix algorithm of Seismograms. For cross-well survey, by this algorithm we can compute the seismograms and its corresponding reflection and transmission coefficients for different locations of sources and receivers with a widefrequency band (0-1000Hz). We show by examples that it is possible to determine the existence of reservoir layers from the waveform records of the different locationsof sources and receivers.
