测井解释利用测井资料识别和评价具有地质意义的储层，可为油气勘探开发提供可靠的地质依据。常规测井资料由于纵向分辨率低，薄储层测井响应特征不明显，在解释时易出现解释结果偏低甚至漏解释。基于技术的发展，中原石油勘探局地球物理测井公司引进并自主研发了高分辨率测井仪。通过现场试验，并与常规测井资料对比分析，找出了影响薄储层解释的主要因素，提出了利用高分辨率测井技术提高薄储层解释精度的思路和方法，取得了很好的地质应用效果。

Well logging interpretation is to accurately identify and evaluate the reservoir having the geological significance by using well logging data, which provides reliable geological parameters for oil and gas exploration and development. Because the vertical resolution is low and the characteristics of thin reservoir logging response is not obvious for the conventional log data, the interpretation conclusion is easily low, even with leakage explanation. Based on the development of science, Geophysical Wireline Logging Company, Zhongyuan Petroleum Exploration Bureau, introduced as well as independently researched and developed the high resolution logging instrument. Through the test and contrastive analysis of conventional logging data, the main influence factors of thin reservoir interpretation were found out, the ideas and methods to improve thin reservoir interpretation accuracy using high resolution logging technology were put forward and good geological application effect has been obtained.
