油藏润湿性评价方法研究

系统总结了油藏润湿性评价的研究现状和新进展。通过综合比较不同的岩心分析方法，认为应在Amott法和USBM法的基础上，深入发展核磁共振、复电阻率和介电测量等快速评价油藏润湿性的岩心分析方法。同时，考虑到电测井、地层测试等方法仅能定性识判油藏的润湿性，建议在基础实验和理论研究的基础上，建立应用测井（核磁共振、复电阻率、介电等）响应评价油藏润湿性的统计模型，连续地、定量地评价油藏的润湿性。

Review of evaluation on the wettability of reservoir

The status and new development of evaluation on the wettability of reservoir was systematically reviewed. From a comparison between various core analysis methods, the author proposed that on the basis of Amott method and USBM method,core analysis methods for fast evaluation of wettbility such as nuclear magnetic resonance,complex resistivity, and dielectric measurement should be developed in higher priority. Considering that electrical log and formation testing can only qualitatively evaluate the wettability of reservoir, it was advised to set up statistical models for well logging (NMR log,complex resistivity log,dielectric log etc. ) responses to quantitatively evaluate wettability based on basic experimental and theoretical study.
