靖安油田长6储层敏感性参数与测井方法的相关性分析

Regression Analysis of Sensitivity and Logging Interpretation Parameters of Chang 6 Reservoir in Jingan Oilfield

在岩心分析资料的基础上 ,分析和提取了靖安油田长 6储层的 12个主要敏感性参数 ,同时利用常规测井方法可获得岩石骨架、泥质含量、粘土矿物、物性等敏感性参数 ,然后在油田储层敏感性流动实验资料的基础上 ,建立储层敏感性与测井解释参数之间的相关关系 ,用逐步回归方法确定其解释模型 ;结合油田实际的储层敏感性评价标准 ,对实际井进行处理分析 ,用测井方法预测储层的敏感性。结果表明由测井解释得到的储层敏感性结论与研究区的敏感性流动实验结果基本一致。

Based on core analysis data, 12 kinds of main sensitivity parameters of Chang 6 reservoir in Jing an Oilfield are acquired and analysed. Meanwhile, these parameters, including rock matrix, shale content, clay mineral and petrophysical property, etc., are obtained from conventional logging. Then, on the basis of flow experiments on reservoir sensitivity, correlation between the sensitivity and logging parameters is set up by using regression method, thus, forecasting and quantitatively analysing the reservoir sensitivity, the result of which proves that the sensitivity from logging interpretation is in good agreement with that of flow experiments on Chang 6 reservoir.
