摘要
以川东北龙会场—铁山区块礁滩相储层为研究对象,针对该区现有储层评价标准与大量强非均质性储层不匹配的情况,基于岩心和测井资料,使用数据挖掘中的因子分析和聚类分析对储层进行定量分类,总结每类储层岩石学、沉积学以及物性特征,建立储层定量评价标准。结合前人研究成果和实际产能资料分析和验证,认为此定量评价和传统定性研究结论一致,且突出了储层相控特征,又提高了储层间的对比精度,更适于本区储层的精细研究。
For reef flat facies reservoir in Longhuichang-Tieshan block in northeast Sichuan,the current reservoir evaluation standards don't match the strong heterogeneity reservoirs. Accordingly,based on core and well logging data,factor analysis and cluster analysis in data mining algorisms were utilized to quantitatively classify reservoirs,define the features of petrology,sedimentology and physical properties of each type of reservoirs,and establish quantitative reservoir evaluation standards. By analysis and verification of predecessors' study results and actual productivity data,this quantitative evaluation result is recognized identical to traditional qualitative study results. Moreover,it highlights the feature of facies controlling on reservoir,and increase correlation accuracy between reservoirs. Therefore,it is more suitable for fine study on reservoirs in this area.
