变质岩潜山岩屑录井资料刻度方法

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。

Calibration method for cutting logging data from metamorphite buried hill

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.
