ASSUMPTIONS OF THE ACCEPTANCE REQUIREMENTS FOR DIGITIZED FIELD SEISMOGRAMS

地质矿产部石油物探研究大队

本文指出我国数字地震观测技术推广后,在原始记录要求上所引起的争论,以及不解决这一问题对工作带来的危害。同时,具体形象地讨论了记录信噪比与有效波的可辨性之关系,估价了当前数字处理的能力。从而,得出在验收时应考虑水平叠加剖面情况的结论,并提出继续重视我国中小型电算站的建设、配套、改革和利用,以及要注意加强我国野外工作方法技术的组织和研究的建议。

Along with the popularization of the digitized seismic acquisition technique, there arose the controversy about the acceptance requirements of the field data. If different opinions couldn't come to identity, the criteria couldn't be laid down promptly so a great deal of harm would certainly be brought to the work. This is indeed a question not to be ignored and it has been pointed out earnestly in this paper. Besides the question mentioned above, the relationship between the signal-to-noise ratio of the record and the identifiability of the effective wave is examined in a figurative way.And, the capability of digital processing at present is evaluated as well. From those mentioned above, the following conclusion can thus be reached that the quality of the horizontal stacked section should be taken into account during acceptance. The building up, the completion, the enlargement and the utilization of the mini and medium computer centers should be paid more attention to. Suggestions about the layout of field work and the problems concerned have been put forward.
