塔里木油田三维定量荧光录井技术研究与应用

Research and application of 3 D quantitative fluorescence logging technology in Tarim Oilfield

针对寻找油气藏的难度越来越大的现状,为了提高塔里木油田油气水层录井综合评价解释符合率,对三维定量荧光录井技术的基本原理、不同储集层三维定量荧光基本特征、评价方法以及应用情况进行了详细介绍。自2003年以来,在大量实验研究基础上,按储集层性质以及不同地区、不同油质分别建立了解释标准,并结合核磁共振录井资料建立了解释图板,在应用中效果显著,油气水层综合解释的符合率不断提高,2006年符合率达92.59%,为油田的勘探开发提供了可靠依据。

According to the condition of being more difficult in finding oil-gas reservoir, and in order to improve the comprehensive evaluating and interpretation coincidence rate of mud logging, the paper introduced 3D quantitative fluorescence logging technology in detail from the basic principle, basic features of 3D quantitative fluorescence for different reservoir, evaluating method and the application condition. From 2003, the interpretation standards have been established in accordance with reservoir properties and different area and different oil grade on the basis of many practical researches, and the interpretation charts have also been established by combining with nuclear magnetic resonance logging information. The application results were remarkable, and the coincidence rate of the comprehensive interpretation for oil and gas zones has been improved continuously, which reached to 92.59 percent in 2006, providing the reliable basis for oilfield exploration and development.
