摘　　要： 由于变质岩潜山的岩性十分复杂,很多岩石在2.5m梯度电阻率和自然电位曲线上差异很不明显,从而使得岩屑录井资料归位和解释常常产生误差。通过对钻井取心、化验分析、试油投产等资料的研究,利用3700系列测井资料建立了一套识别变质岩潜山岩性的方法,将地质录井资料与该方法的识别结果结合使用,能克服地质录井资料分辨率低、连续性差和易受人为因素影响等弱点,提高了在变质岩潜山中岩屑录井剖面的准确性。 Due to the complexity of the lithology of metamorphite buried hill, there was not considerable discrepancy for many kinds of rock at 2.5 m gradient resistivity and SP cusves, thus making cutting logging data classification and interpretation often produced errors. Through studying data from drill-coring, chemical examination and analysis, oil testing and putting into production etc., and making use of 3700!series well logging data, the paper set up a set of method for identifying metamorphite buried hill lithology, combining its identifying results with geo-logging data could overcome the weaknesses of geo-logging data in the low resolution and poor continuity and the problem easily affected by human factors, thus enhancing the accuracy of cutting logging profile from the metamorphite buried hill.
