钻井液中携带的烃类气体能够及时准确的反应地层中的含油气情况,现场对钻井液中烃类气体的检测是油气勘探过程中发现油气的一种重要手段。烃类组分中戊烷以后的重组分在常温常压下表现为液态,现场录井中无法完成气态输送,导致现有的气测录井技术只能在线检测C1~nC5七种组分。探索重烃组分的现场输送方法,对于增加现场烃类组分检测种类,解决重烃组分无法进行现场在线分析的问题具有一定的指导意义。
Hydrocarbon gas carried in the drilling fluid can timely and accurately reflect the hydrocarbon-bearing conditions in the formation. The on-site detection of hydrocarbon gas in the drilling fluid is an important means for discovering oil and gas in the process of hydrocarbon exploration. The heavies after the pentane in the hydrocarbon component are liquid at normal temperature and pressure, and the gas transportation can not be accomplished in the field logging, resulting in that the existing gas logging technology can only detect the seven components C1 ~ nC5 online. It is instructive to explore on-site transportation of heavy hydrocarbon components in order to increase the types of on-site hydrocarbon components and solve the problem of on-line analysis of heavy hydrocarbon components.
