玛湖南斜坡区白碱滩组、上克拉玛依组气测录井解释新方法的研究

Study on New Method for Gas Logging Interpretation of Baijiantan and Upper Karamay Formation in the Southern Slope of Mahu

摘要: 利用玛湖南斜坡区白碱滩组、上克拉玛依组气测录井资料对研究区储层价值性展开研究分析。结果表明，传统的气测解释评价法如双对数比值法、轻烃比值法、气体正规化法等不适用于研究区储层的评价。通过原始数据深入挖掘，发现气测含油性指数与烃相系数对储层价值性的判别具有明显作用，以此建立了气测录井图版和解释标准。经验证，新图版解释评价效果较好，具有一定的应用价值。

Abstract: The gas logging data of Baijiantan Formation and Upper Karamay Formation in the southern slope of Mahu are used to study and analyze the reservoir value in the study area. The results show that the traditional gas interpretation and evaluation methods, such as dual logarithm ratio method, light hydrocarbon ratio method and gas normalization method, are not suitable for the reservoir evaluation in the study area. Through deep mining of original data, it is found that the gas logging oil index and hydrocarbon phase coefficient have significant effect on the identification of the res-ervoir as the value layer; thus the gas logging chart and interpretation standards are established. It has been proved that the new chart interpretation and evaluation effect is good and has certain application value.
