| 摘 要： | 通过物理模型进行了井间地震观测系统的研究，利用井间地震观测系统的排列方式易于变换的特性，提出应用不同选排道集空间即共炮点道集、共接收点道集和共偏移距道集来识别和分离复杂的井间波场。对共偏移距道集空间数据分析和应用作了较详细的叙述。实验结果表明，采用共偏移距道集分析井间波场比共炮点道集或共接收点道集更方便，显示更清楚，更有利于确定地层特征和构造模式。

| Abstract: | This paper studies crosswell seismic using phys-ical model. Taking advantage of the variability of thespread pattern of crosswell observation system. theauthor discussed to identify and decompose crosswellwavefield in common shot gather, common receivergather. or common offset gather. The aspects of cr-osswell seismic data analysis on the common offsetgather are described in detail. Experiments showthat. comparing to the common shot gather and com-mon receiver gather, it is more convenient to performcrosswell wavefie1d analysis on the common offsetgather. The clearer definition of the resulted wave-field is favorable for the determination of stratigraph-ic features and structural pattern. |
