Research Of Bin-divisible Method And Evaluating Techniques For High Density Seismic Data

With development of exploration, looking for a small block, small construction, subtle reservoirs has become a target for exploration. The development of digital acquisition system, in particular the large numbers of traces seismograph's using, we can process seismic data in room within small sample interval and small bin. High density is not a long history for exploration. There are not enough theoretical cognition and quantitative criterion for affection of bin size and method to signal to noise ratio and resolution. As the signal to noise ratio and resolution is linked to a certain extent, research on the relationship between bin-divisible and S/N can eventually help us understand the exploration precision . By increasing the fold, velocity spectrum may be improved. But how much the improvement is, there is relatively little previous research. Therefore, systematic research on bin-divisible methods and the relationship among bin-divisible, the signal to noise ratio, resolution, the velocity spectrum has important theoretical significance and practical application value.This article first detailed the research status of bin-divisible processing technology at home and abroad and then studied the relationship among bin-divisible, the signal to noise ratio, resolution, fold and the velocity spectrum. On this basis, taking Yongxin area as an example, we deduced the quantitative relationship among bin-divisible, the signal to noise ratio, resolution, fold and the velocity spectrum, which will be an important guide for the next high-precision three-dimensional seismic exploration.
