| 摘 要： | 三维三分量（3D3C）VSP是集井中地震、多波勘探为一体的地震勘探方法，因3D3C VSP资料既含有精确的深度信息又含有丰富的地层岩性信息，较地面地震有不可比拟的优势。但是由于3D3C VSP特殊的观测方式，需要有特定的处理和解释方法。针对实测的斜井三维VSP多波资料，分析斜井三维VSP多波资料的特点，研究了一系列处理和解释方法，其中包括：选排、速度分析、动校正、层位标定、层位对比及叠前反演等，实现了斜井三维VSP多波资料的处理及解释。

| Abstract: | Since the three-dimension and three-component (3D3C) VSP data contain KG(0.06mm]not only exact depth information but also rich lithologic information of strata, so it has incomparable advantages over surface seismic data. However, because of its special observation mode, specific processing and interpretation methods are needed. We analyze the characteristics of a deviated-well 3D3C VSP data, and propose a few methods for its data processing and interpretation, including sorting, velocity analysis, normal moveout correction, horizon calibration, horizon correlation and prestack inversion. The processing and interpretation results of the deviated-well 3D3C VSP have been obtained. |
