以多层地质模型为基础，利用速度随深度线性关系推导出一种新的时深转换方法。该方法应用于大庆探区断陷盆地的三维地震资料解释中，弥补了以往用分层统一速度作图方法的不足，见到了很好的效果。所绘制的构造图深度同实际钻井深度吻合较好，且成功地预测了无钻井区的地层深度。
Based on the multi-layer geological model, a new time-depth conversion method is derived by using the velocity-depth linear relationship. This method is applied to the interpretation of 3D seismic data in the Daqing exploration zone faulted basin, which makes up for the shortcomings of the conventional method of laying the uniform velocity using the stratified method and has seen good results. The constructed depth of tectonic map is in good agreement with the actual drilling depth, and the depth of the formation without drilling zone is successfully predicted.
