| 摘 要： | 对井间地震进行了系统研究，分析了观测系统和井间地震波场的特征，提出了一种处理井间地震资料的新方法，由理论推导得到了井间反射波的旅行时方程。利用井间地震特有的共偏移距道集，找出了适宜于分析井间地震偏移速度的方法。在此基础上，进一步研究了井间地震反射波偏移成像的超级叠加技术。通过对有限差分模型资料和实际资料的处理，获得了清晰的反射波剖面，验证了反射波超级叠加技术的有效性和可靠性。

| Abstract: | By the use of the crosshole seismic technology, the observation system and characteristics of crosshole seismic wave field was analyzed. A new method for seismic data processing is proposed. The travel time function of reflects is given by theoretical analysis. Using special common offset gather for crosshole seismic, a migration velocity analysis method is developed for crosshole seismic.Further a super stack method is developed. A clear reflect profile is obtained from processing data of finite differential model and real crosshole seismic. The validity and reliability of these methods are proved. |
