塔里木盆地库车坳陷资料处理方法初探

在塔里木盆地库车坳陷南部部署的库1井得到了较好的油气显示。初步探讨了地面地震资料、VSP资料、测井资料的处理方法。利用合理的处理流程可以得到波组特征清晰，信噪比高的偏移叠加剖面，能够满足该区的勘探要求。合理的VSP施工方法，可以获得高品质的VSP原始三分量资料，原始VSP资料波场信息丰富，反射波清晰，VSP处理结果可以对地面地震资料进行精确标定。根据VSP资料提取地球物理参数，结合测井解释、岩屑录井和地质录井显示的结果进行综合分析。应用4种技术对测井资料进行处理，取得了较好的结果，可以对储层的含油气性进行综合评价。

Discussion about the processing methods for data from Kuche Depression of Tarim Basin

The good indication of oil and gas in well Ku-1 suggests that the south part of Kuche Depression should be a prospect area in Tarim Basin. The processing methods for surface seismic data, VSP data, and logging data were discussed. A reasonable processing flow ensured to yield migration sections with clear reflection character and high signal noise ratio. High quality 3 component VSP data was used to calculate geophysical parameters. In combination with logging, cutting logging, and geological logging information, the results were used for integrated analysis. The evaluation of hydrocarbon potential for a reservoir was performed on the high quality logging data that was processed with four techniques.
