发展应用新技术寻找经济增长点——关于地震勘探野外检波器组合技术的一点看法及建议

APPLICATION OF NEW TECHNIQUES TO REDUCE EXPLORATION INVESTMENT

目前野外施工所采用方法有检波器组合、多次覆盖、三维勘探;室内处理消除面波的方法更多,并且也很有效,成本更低。野外取消检波器组合技术,所得资料经过室内面波压制处理,其所得叠加剖面与经过野外检波器组合所得资料的叠加剖面相比,分辨率与信噪比应该差别不大,若这一结论成立,野外应该根据工区情况,部分甚至全部取消野外检波器组合,这对降低石油勘探与开发的成本具有重要意义。

At present, we have several methods to remove surface wave in the field data acquisition, such as geophone combination, multiple coverage, 3D exploration etc. In a workstation, there are more methods to remove the surface wave, which are more efficient with much lower cost. If the resolution and S/N ratio of the data collected without geophone array through surface wave removing in a workstation reaches almost the same that of data collected with geophone array, the geophone array can be cancelled partly or completely according to the field situation. Exploration investment can be significandy reduced by this way.
