摘　　要：华北测井公司已经完成两口井的ＭＲＩＬ资料采集和解释应用。本文以这些资料为基础，报告ＭＲＩＬ提供的有效孔隙度和渗透率在该地区的适应性；对常规测井资料解释结果与ＭＲＩＬ解释结果进行对比分析；对ＭＲＩＬ结合中子／密度孔隙度及电阻率综合解释油气水进行试油检验，并利用井壁声波成象测井（ＣＢＩＬ）对试油结果进行讨论；然后，尝试利用薄层电阻率测井（ＴＢＲｔ）提高ＭＲＩＬ的纵向分辨率。适应性分析表明，ＭＲＩＬ提供的有效孔隙度、渗透率与岩心分析值有很好的一致性，提供的束缚水孔隙体积使储层产液性质的判断更加准确。Ｔ２截止值对解释结果有相当大的影响。含油性解释及试油结果表明：ＭＲＩＬ与电阻率及中子／密度孔隙度综合解释获得的油水饱和度，有一定的准确性，ＴＢＲｔ提高了ＭＲＩＬ识别薄油层的能力。Huabei logging company has completed two MRIL jobs which are quite successful. The work done on the MRIL data includes: ① the adaptability analysis of MRIL effective porosity and permeability to this specific area; ② comparison between conventional log interpretation result with MRIL based evaluation result; ③ well test and well test result analysis with CBIL and ④MRIL vertical resolution improvement with TBRt. The adaptability analysis indicates that MRIL effective porosity and permeability are fully consistent with core analysis results, and that MBVI provided by MRIL makes the producing fluid evaluation more accurate.The determination of T(2, cutoff) value has a great influence on the interpretation result. The well test result proves that the oil and water saturation from the synthetic interpretation of MRIL, Resistivity and Neutron/Density logs are accurate to a certain degree. TBRt is helpful to enhance the resolution of MRIL and CBIL can explain the abnormal phenomenon in well test result.
