摘要
直罗油田延长组储层渗透率低,泥质含量高,油水层识别难度大。在采用多参数层次分析法对储层进行评价的基础上,分油层组建立了孔隙度、渗透率、含油饱和度、泥质含量的测井解释模型和油水层解释图版,并应用模型对研究区探井进行了二次解释。通过14口井单层的试油资料验证,油水层解释符合率超过80%。
Yanchang-Formation reservoirs in Zhiluo Oilfield are characterized by low permeability,high shale content and difficult to identify for the oil and water reservoirs.Based on the reservoir evaluation by multi-parameter analytic hierarchy process,the logging interpretation models of the porosity,permeability,oil saturation,shale content and oil ＆ water layer interpretation charts for each oil group are established,the secondary interpretations are conducted for the exploring wells in the study area by means of the models.Proven by the oil test data of the individual layers of 14 wells,the oil ＆ water layer interpretation coincidence rates are more than 80％.
