普光气田上部陆相储层多由复杂碎屑岩组成,岩性成分多样且非均质性较强导致储层多呈低孔低渗特征,给储层的识别和评价带来较大的难度。通过储层分类开展测井响应特征研究,及进行测井四性关系分析,本文针对普光气田上部陆相储层的特点,建立了基于常规测井资料,结合录井及岩心分析等资料,进行储层定量评价的方法和标准。
The upper continental facies in the Puguang Gas Field are mostly composed of complex clastic rocks with various lithologic components and strong heterogeneity, which leads to low porosity and low permeability characteristics of the reservoirs, which brings great difficulty to the identification and evaluation of the reservoir . According to the characteristics of the upper continental reservoir in the Puguang gas field, based on the conventional well logging data, combined with logging and core analysis, etc., the logging response characteristics are studied through reservoir classification. Methods and standards for quantitative evaluation of reservoirs.
