通南巴地区灰岩区地震采集方法探讨

通南巴地区灰岩地震采集是2003～2004年度南江地区地震勘探的重点与难点,能否采集好灰岩地震资料,关系到整个通南巴地区地震勘探效果,研究适合的灰岩区野外地震资料采集方法,得好第一手资料,提高灰岩地震资料信噪比,开展通南巴地区灰岩采集方法研究,对指导今后该区地震勘探工作具有重要意义。本文通过对通南巴灰岩区大量针对性试验资料分析及地震地质条件的分析,结合部分施工测线的资料分析,总结了对该区灰岩资料特征的认识,同时为以后通南巴地区的灰岩区资料采集提出了比较合理的施工方案及可行性建议。

ON SEISMIC DATA COLLECTION METHOD IN LIMESTONE AREA OF TONGNANBA AREA

The limestone data collection for seismic survey in Tongnanba area is important in whole Nanjiang areas from 2003 to 2004, so whether or not the data can be well obtained has much to do with the prospecting effect in whole Tongnanba area. In order to get nice first hand information and increase signal-to-noise of the data, it is very important for seismic survey in this area to study appropriate field seismic data collection method for limestone areas. By analyzing a large number of concerned test data and seismogeological condition, together with partial execution line data, this paper summarizes limestone data characteristic in this area, and meanwhile it puts forward relative rational construction scheme and feasible proposal for later limestone data collection in Tongnanba areas.
