单井示踪剂法测残余油饱和度技术应用

Application of single well tracing methods for themeasurement of residual oil saturation.

单井示踪剂法是一种新兴的测残余油饱和度方法。它具有快速、准确、优越等特点。近年来，该方法被广泛应用于高含水油田中，测定目前油层中的残余油数量及分布情况，为研究油层物性和三次采油提供依据。本文介绍了该方法的发展状况，并重点概述该方法的原理及其在胜利石油管理局孤东小井距开发试验区三次采油中的应用。

ingle well tracing method is a new method for measuring residual oil saturation ,it is charac-terized by promptness and accuracy. This method is being widely used in high water cut oilfield to measure the volume and distribution of residual oil and provide basis for the researchof oil reservoir properties and tertiary oil recovery. This paper presents the development ofthe method ,discusses the principle of the method and its application in the tertiary oil recov-ery of the dense well spacing development area in Gudong oil field of Shengli Petroleum Ad-ministration.
