气测录井经过多年的应用研究与实践取得了长足的进展,发现与解释评价水平不断提高,但一些解释方法尚需深入研究。该文从钻井液循环过程中气体组分关系的变化入手,探讨了组分关系的变化在不同气测参数比值上的变化特征;结合塔里木油田气测录井应用情况,对油、气、水层各气测比值参数变化特征的一些规律性的认识进行了探索性的总结;倡导对不同地区、不同地质特征的气测录井解释应在注重其特殊性的基础上进行综合解释,来提高解释评价水平。该文对气测比值在油、气、水层变化特征的一些规律性的认识与归纳对引导气测录井解释向深层次发展具有指导作用。
After many years of applied research and practice, gas logging has made great progress, and the level of discovery and interpretation has been continuously improved. However, some interpretation methods still need further study. This paper starts with the change of the gas components in the circulation of drilling fluid, and discusses the changing characteristics of the relationship between components in the ratio of gas measurement parameters. Combining with the application of gas logging in Tarim oil field, Layer gas measurement ratio of the characteristics of some of the characteristics of the regularity of the understanding of the exploratory summary; Advocate for different regions, different geological features gas logging interpretation should pay attention to its particularity based on a comprehensive explanation to improve Explain the level of evaluation. The recognition and induction of some regularities of gas-oil ratio in oil, gas and water layers can guide the interpretation of gas logging well to deep-seated development.
