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，ＣＢＩＬ则对试油结果中的一些疑难问题提供了解答
North China logging company has completed the MRIL data acquisition and interpretation of two wells. Based on these data, this paper reports the suitability of MRIL for effective porosity and permeability in this area; comparative analysis of interpretation results of conventional log data and MRIL interpretation; comparison of MRIL with neutron / density porosity and resistance Rate comprehensive interpretation of oil and gas water test oil test and the use of borehole acoustic imaging logging (CBIL) to discuss the results of the test oil; and then try to use the sheet resistivity log (TBRt) to improve the longitudinal resolution MRIL. The adaptive analysis shows that the effective porosity and permeability provided by MRIL are in good agreement with the core analysis values, and the irreducible water pore volume is provided to make the judgment of fluid production properties more accurate. The T2 cutoff has a considerable impact on the interpretation. The results of oil-bearing interpretation and oil-test show that there is a certain degree of accuracy for MRIL and oil-water saturation obtained from the comprehensive interpretation of resistivity and neutron-density porosity, that TBRt improves the ability of MRIL to identify thin oil layers, Some difficult questions in the answer
