摘要
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在不断提高,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。
Gas logging has made considerable progress through many years′ applied research and practice, the level of finding and interpretative evaluation has also steady improved, but some interpretation methods still need further research. The paper discusses changeable characteristics of component relation′s variation in ratio of various gas logging parameters, proceeding from the gas components′ changeable relation during drilling fluid circulation. Combining with the gas logging application situation in Tarim oilfield, the paper summarizes some regular cognition about changeable characteristics of every gas logging parameter ratio of oil-gas water layers, proposing the comprehensive interpretation to different areas and different geological features while paying attention to their speciality, to raise the level of interpretation and evaluation. Some regular cognition and conclusion in this paper, which are drawn from changeable features in oil-gas-water layer′s gas logging ratio, play a positive function in guiding gas logging interpretation development to advanced stage.
