    摘要:

    东营凹陷利津北带砂砾岩体储层矿物组分复杂,物性参数解释精度低,油、干层界限难以界定。基于测井、录井、试采、分析化验等资料,采用交会图版识别和雷达图形模式识别岩性方法,较好地区分了砂砾岩体岩性。在岩性识别、含油产状分析、试采资料分析基础上,分别建立了砾岩类和碳酸盐岩类有效储层的物性和电性下限。结合试采资料,建立了利津北带砂砾岩体有效储层分级解释图版与评价标准。分别建立了砾岩类和碳酸盐岩类储层孔隙度和渗透率参数模型,为利津北带复杂砂砾岩体储层提供定量评价方法。该研究成果在利津北带砂砾岩体投产井中得到了应用验证,效果良好。

    Abstract:

    Glutenite reservoirs in the north region of Lijin,Dongying Sag have complex mineral components,resulting in the low accuracy of the interpretation of physical parameters and the difficulty of defining the boundary of oil and dry layers. Based on the data of logging,mud logging,production test,and analysis testing,this paper combined crossplot chart identification with radar pattern recognition mode to effectively distinguish glutenite lithology in the area. Based on the lithology identification, oil-bearing occurrence analysis, and testing data analysis, this paper established the lower limits of physical and electrical properties of effective conglomerate and carbonate reservoirs. Combining with the production test data,this paper constructed the interpretation chart of classification and evaluation standard of the effective reservoir of glutenite in the north region of Lijin,Dongying Sag,and built the porosity and permeability parameter models of conglomerate and carbonate reservoirs,respectively,which provided a quantitative evaluation method for complex glutenite reservoirs in the north region of Lijin,Dongying Sag. The application has verified the research in the production wells of glutenite reservoirs in the north region of Lijin,Dongying Sag,and the results are promising.
