【摘要】 针对小层对比工作在复杂构造、多断层油藏很容易出现分析失误,使油水井注采关系不清,区块完善程度不清,给地质研究、动态分析和开发决策造成严重的影响,本文以吉林油田扶余采油厂西区的小层对比分析为例,采用常规油层对比的同时,结合构造位置、构造趋势及钻井地质录井资料等,进行了多井分析判断,及时发现断层。通过对1984年以来728口新井小层对比分析,特别是对14口钻遇断层井的分析,经三维地震资料验证,与分析结果基本吻合,进一步完善了油层对比方法。更多还原

【Abstract】 The dynamic analysis of oil reservoir is important both in theory and in practice.According to a comparison analysis,the faults of mini-oil layers on complex structures and the multi-faults of oil reservoir would make the production-injection relation of the oil and water wells and the block completion degree unclear and wouls even have thorny effects on the whole geological research.The dynamic analysis,a new approach of perfecting the comparison method on the oil layers is carried out for an example for the comparison analysis on the mini-oil layers of the western fourth section of the oil extraction area of Fuyu in Jilin oilfield in this paper.The multi-wells are analyzed to discover faults betimes by adopting conventional comparison on the oil layers and considering the position of the geological formation,the tendency of geological formation and the drilling geologic logging data.The analysis results of three-dimensional seismic data show that the drilling faults and the neighborhood fault wells are consistent basically with the comparison analysis on the mini-oil layers of 728 new wells,especially,the fourteen drilling meeting faultage wells from 1984.The comparison methods of the oil layers are further improved for the further development of oil fields to obtain the relationship between the production-injection of the oil and water wells,which may provide a guide for practical work in the oil field.更多还原
