R型因子分析低饱和油藏评价方法研究

R-type Factor Analysis Method for Evaluating Low Saturation Reservoir

蠡县斜坡低饱和油层录井参数响应特征与油层相似,但试油时油水同出,增加了地层流体准确识别的难度。使用SPSS软件,在对研究区流体性质录井响应特征深化研究的基础上,优选出7个敏感参数,对蠡县斜坡46个试油层的各项录井、测井参数进行R型因子分析,挖掘出两个因子,建立了因子分析二维解释图版,对储层流体性质进行评价。该模型在蠡县斜坡应用33口井,其中22层经试油验证,解释符合率达到77.3%,提高了5个百分点。

The logging parameter response characteristics of lixian slope low saturated oil layer are similar to that of oil layer,but the oil and water are both produced during oil testing,which increases the difficulty of accurate identification of formation fluid.Using SPSS software,the fluid properties in the studied area deepen the research on the basis of logging response characteristics,optimizing the seven sensitive parameters,have to at lixian county after slope 46 try reservoir logging,well logging parameters R factor analysis,digging out of two factors,factor analysis of two-dimensional interpretation chart is established,and to evaluate the laminar liquid storage.The model has been applied to 33 Wells in Lixian slope,among which 22 layers have been verified by oil test,and the interpretation coincidence rate is 77.3%,which has increased by 5 percentage points.
