摘要
配合脉冲中子地层元素测井仪的应用,开展地层元素测井解释方法研究,获取地层元素标准谱库,编制地层元素解释软件,解释得到元素产额、干重(不含结晶水的质量百分含量)、矿物组分含量。取芯井对比结果显示,解释结果与取芯化验结果一致性较好,研究结果可为复杂岩性评价、准确计算孔隙度提供数据。
In order to apply pulse neutron formation elements logging tool,thon the interpretation method of the formation elements logging was performed. A stand-ard spectrum library of the formation elements was obtained,and an interpretation sof-- ware was compiled,through which,the element yield,dry weight （mass percent content without crystalline water） and mineralogical composition could be obtained. Comparing the interpretation results with the data from the cored well showed that tion results had a good consistency with the core test results,whifor the evaluation of complex lithology and accurate calculation of porosity.
