| 摘 要： | 本文首先从地震勘探的基本原理出发，分析地震反演解决地质问题的本质；然后从基础资料的品质、测井约束地震反演方法及反演参数的选择，地层格架模型建立和外推控制三个方面，分析、探讨测井约束地震反演解决地质问题的能力；最后认为，测井约束地震反演解决地质问题的能力是有限的，并提出了提高测井约束地震反演解决地质问题能力应重视的几个因素。

| Abstract: | The paper began with the basic theories of seismic exploration,analyzed the nature of solving geologic problems using seismic inversion. Then we analyzed and discussed the impact on ability of using well log constrained inversion to solve geologic problems from three aspects:quality of basic data,the method of well log constrained inversion and the selection of inversion parameter and building up the model of stratigraphic framework and extrapolation control.Finally,we conclude that the ability of using well log constrained inversion to solve geologic problems is limited and propose several aspects we should pay attention to in order to improve the ability of using well log constrained inversion to solve geologic problems. |
