膜渗透气体分离技术应用于气测录井中已有多家机构做了研究和尝试,大庆钻探录井一公司研制开发了Gaswizard(GW)接触式烃类气体检测系统,该系统气体探头体积小,可以方便地安装于井口钻井液出口处,只要有少量的钻井液返出,其探头就能连续检测出口的烃类气体含量,并具有检测值响应迅速、定量的特点,也可以在起下钻和接单根过程中对井口烃类气体含量进行检测,这为解决空气、泡沫等欠平衡钻井环境下电动脱气器难以发挥作用的难题提供了条件。通过10余口井现场试验应用,表现出检测迅速、曲线呈指峰状的特点,对显示层细分十分有利,同时能够提前发现烃类异常,有利于有效地保证钻井安全。
Membrane permeation gas separation technology used in gas logging has been a number of agencies have done research and try Daqing drilling logging company developed a Gaswizard (GW) contact hydrocarbon gas detection system, the system gas probe is small, Can be easily installed at the exit of wellhead drilling fluid, as long as there is a small amount of drilling fluid to return, the probe can continuously detect the export of hydrocarbon gas content, and the detection value of rapid response, quantitative characteristics, And then a single root process hydrocarbon content of wellhead gas detection, which is to solve air, foam and other underbalanced drilling environment, electric deaerator difficult to play the role of the problem. Through more than 10 wells in field test applications, the test shows rapid detection and the curve refers to the peak shape, which is very beneficial to the display layer subdivision. At the same time, hydrocarbon anomalies can be found ahead of time, which helps to ensure the drilling safety effectively.
