:Coiflet3基函数在研究工区中应用效果最好；将第一核主成分进行6级分解,并根据第5级和第6级能谱最大差法确定的油水界面与生产测试资料十分吻合；油水界面高度由西向东呈先增大后减小的趋势,与储层岩性,物性的平面变化特征一致. 关键词:油水界面；核主成分；能谱分析；小波基函数；Coiflet3基函数 中图分类号:P631.8+4 ... spectrum. The oil-water contact distribution of the whole reservoir was determined based on the analysis of single well. The results show that Coiflet3 base function is best applied in the study area......
