井间观测系统的讨论

Discussions on cross-well observation system

如何选择井间观测系统，对于地震层析成像而言，是至关重要的。因为不同的井间观测系统，不但在野外工作效率上，而且在其层析成像的结果上，可能极不一样。本文将根据直射线的SIRT方法，通过不同井间观测系统对成像质量的影响，提出了选择井间观测系统应遵循的某些原则，进而获得炮间距、道间距和最大排列长度间的估算关系。

How to select a cross-well observation system is very important for seismic tomography.Different cross-well observation system will greatly affect tomographic results and field efficiency.According to a SIRT method, by discussing tomographic results of different cross-well observation system, this article presents some useful criteria of selecting a cross-well observation system in order to obtain some approximate relations among shot interval, trace interval and maximum array length.
