地球化学测井在中原油田储层评价中的应用

. Application of GLT to Reservoir Evaluation of Zhong-yuan OilField

焦大庆，王德仁，费伯良．地球化学测井在中原油田储层评价中的应用．测井技术，１９９４，１８（ｌ）：５５～６１ＧＬＴ是斯仑贝谢研制的新仪器，它测量地层元素的丰度，并将其转换成矿物含量。本文介绍了地球化学测井的原理及测量精度．重点论述了ＧＬＴ测井在中原油田的应用效果。它在储层评价中的应用情况如下：获取地层的物性参数．计算粘土矿物含量，区别沉积体系，划分沉积相带．推断成岩演化，判断储层孔隙类型，了解胶结物成分为改造油层提供资料．指示沉积环境，判断是否存在低电阻油层。总之，它为研究人员提供了多种信息。文章也指出了ＧＬＴ测井在中原油田应用中存在的问题及发展前途。

eochemical logging is a new logging technology developed by Schlumberger. It measures the abundance of elements found in the formation and then converts it to minerals concentration. After introducing the principle of Geochemical Logging and the measuring precision of GLT the paper expounds mainly the application results of GLT in Zhongyuan OilField. its applications are as follows:Derive physical properties of the formation such as porosity, Permeability and oil saturation ;Calculate clay mineral concentration;Identify depositional pattern;Classify sedimentary factes;Deduce diagenetic processDetermine pore types of reservoir and cement compositions;Indicate depositional environment;Determine the existence of low resistivity oil bearing zone.Finally, both the existing problems and its prospects in the application in Zongyuan OilField are pointed out as well.
