【摘要】 鉴于井间地震资料波场的复杂性，现在多数情况下只能利用初至波的旅行时数据来进行井间层析成像。本文将VSP资料处理技术应用于井间地震资料之中，对两个共炮点道集和两个共接收点道集的上下行反射波作了井间成像，获得了十分理想的高分辨率成像剖面。分析结果表明，这种剖面的地震分辨率比VSP成果剖面约高4～5倍。此项处理技术有效地提高了原始资料的利用率。更多还原

【Abstract】 In view of the complexity of crosshole seismic wavefield,crosshole tomographicimage can be usually achieved by using first break time. Applying VSP data processing technique to crosshole seismic data,we accomplished crosshole image of upgoingand downgoing reflection waves of two common-shot trace gathers and two commonreceiver trace gathers, finally obtaining satisfactory high-resolution sections. It isanalytically shown that the resolution of this kind of section is four or five timeshigher than the resolution of VSP section. This technique effectively increases theapplicability of raw data.更多还原
