【摘要】：在气测录井中,传统的搅拌式电动脱气器存在体积大、影响因素多、脱气不定量等问题,传统气测录井存在检测组分少导致信息不充足等缺点。针对上述问题威德福公司研发的GC-Tracer半透膜多组分气体检测系统,采用半透膜脱气器代替传统搅拌式电动脱气器,具有体积小、安装灵活、脱气效率稳定、受外界干扰小等优点;多组分气体检测系统可在60s内实现C_1-C_8、苯和甲苯、二氧化碳的检测,大幅增加了地层检测信息量。现场应用结果表明,以定量脱气及多组分气体检测为基础,可准确发现油气层,快速精确评价地层含油气信息,能更好地服务于勘探开发,在深海录井、非常规录井、欠平衡录井、混油钻井液录井等方面具有很好的应用前景。
[Abstract]:In gas logging, the traditional agitated electric degassing device has many problems, such as large volume, many influencing factors and unquantitative degassing, etc. The traditional gas logging has some shortcomings, such as insufficient information due to the lack of detection components and so on. To solve the above problems, the GC-Tracer semi-permeable multicomponent gas detection system developed by Weidford Company has the advantages of small volume, flexible installation, stable degassing efficiency and little interference from the outside world by using semi-permeable membrane degassing device instead of the traditional stirred electric degassing device. The multicomponent gas detection system can realize the detection of C _ 1-C _ S _ 8, benzene and toluene, carbon dioxide in 60 s, which greatly increases the information of stratum detection. The field application results show that based on quantitative degassing and multicomponent gas detection, oil and gas layers can be accurately found, and oil and gas information can be evaluated quickly and accurately, which can better serve exploration and development, and can be used in deep-sea logging and non-conventional logging. Underbalanced mud logging and mixed oil drilling fluid logging have good application prospects.
