摘要
本文认为利用VSP方法在多口井中及井区地面同时进行三分量观测，有可能形成一种立体地震勘探方法，用于解决油气田开发与开采阶段的许多地质问题。文中详细地介绍了这种立体地震勘探方法的基本原理、观测系统及资料处理和解释方法。利用这种方法可以提供速度、杨氏模量、泊松比、拉梅常数、应力及反射系数和吸收系数等信息；在分析地震波场的运动学和动力学参数及其相互关系随时间变化的基础上，可对有关油田开发过程中许多问题作出预测，以便实时调整油气田的开采方案。
VSP-like three-component observations conducted simultaneously in boreholes and on surface of the borehole area may be said to be cubical seismic exploration,which can be used to solve many geologic problems in hydrocarbon field development. Its principle, observation system, data processing and data interpretation are described in detail. This method can be introduced to offer many informations:velocity, modulus of elasticity, Poisson's ratio, Lame constants, stress, reflection coefficient,absorption factor and so on. In addition,by analysing the dynamic & kinematic parameters of wave field,and their relation which vary with time,people can predict many problems in hydrocarbon development so as to adjust development scheme in time.
