摘要

渤海L油田属于目的层段地震资料品质差、含油井段长、对比标志层少的河流相油田,小层对比存在较大难度。采用"三步法"多信息小层对比技术对长含油井段逐级进行了细分对比,将L油田地层划分到小层单元;经现场动态资料验证,该方法可以有效降低小层划分与对比的多解性,增加小层对比的可信度。
As an oilfield of fluvial facies in Bohai water,L is characterized by low-quality seismic data in the target zones,long oil-bearing intervals and sparse key beds,in which it is difficult to make subzone correlation.Therefore,a method of three-step subzone correlation with multiple information integration was used to progressively subdivide the long oil-bearing intervals into subzone units and correlate them in L oilfield.According to a test by the field performance data,this method can effectively reduce uncertainty in subzone division and correlation and increase reliability in subzone correlation.
