目的:介绍合成地震技术关键步骤。方法:详细分析了由时.深转换而形成的垂直时距关系与地震资料的垂直时距关系相比存在误差的原因,提出了两种校正方法:①常用的利用垂直地震测井资料进行校正的方法;②用已经钻井证实的地面地震资料与合成地震资料做对比,找出相应的差值,作为经验校正系数进行校正。结果:以中原油田为例,通过实际处理得出在中原油田校正值为10%。结论:该方法既经济又实用。
Objective: To introduce the key steps in synthetic seismic technology. Method: Detailed analysis by the time. Two kinds of correction methods are proposed: ① commonly used method of vertical seismic logging data correction; ② have been confirmed by drilling confirmed that the vertical distance between the formation of the vertical distance and seismic data compared to the vertical relationship between the reasons for the existence of error, Of the surface seismic data and synthetic seismic data to compare, find the corresponding difference, as the empirical correction coefficient correction. Results: Taking Zhongyuan Oilfield as an example, the corrected value of Zhongyuan Oilfield is 10%. Conclusion: This method is both economical and practical.
