摘要
为进一步提高地化录井技术在储集层流体性质评价中的精度,选取渤海油田垦利X区块中地化录井、测井及测试资料丰富的7口井138个壁心岩石热解分析结果为样本,从中优选出5个反映储集层流体性质的参数,通过主成分分析法提取主成分F_1和F_2,并建立了主成分识别储集层流体性质图板。应用主成分分析法可以有效区分油层及水干层,提高储集层流体识别的精度,在储集层流体性质评价中具有良好应用前景。
In order to further improve the accuracy of geochemical logging technology in reservoir fluid property evaluation,the results of rock pyrolysis analysis of 138 sidewall cores in 7 wells,which are rich in geochemical logging,well loggingand testing data in Kenli X block,Bohai Oilfield,were taken as samples.Five parameters of reflecting the fluid properties of the reservoirs were optimized.Principal components F1 and F2 were extracted by principal component analysis method,and the chart of principal component identifying reservoir fluid properties was established.The application of principal component analysis method can effectively distinguish oil layers and water-dry layers,and improve the accuracy of reservoir fluid identification.The results show that it has good application prospects in reservoir fluid property evaluation.
