油井天然气中硫化氢浓度检测方法的探索与实践
|
摘要
在石油开采过程中,硫化氢分布规律复杂多变,其来源主要有钻井因素、井下作业因素,采油措施中的酸洗、注水因素等。硫化氢有剧毒,一旦泄漏,后果不堪设想。因此,要提前预知现场采油过程中的井口、计量间、转油站等日常取样及泄放口位置硫化氢气体的浓度值,提前做好防范措施,告知现场作业人员务必注意预防硫化氢中毒事件的发生。
In the process of petroleum exploitation,the distribution of hydrogen sulfide is complex and changeable.The main sources of hydrogen sulfide are drilling factors,downhole operation factors,pickling in oil recovery measures,water injection factors and so on.Hydrogen sulfide is highly toxic,once leaked,the consequences are unimaginable.Therefore,we should predict in advance the concentration of hydrogen sulfide gas in the wellhead,metering room,oil transfer station and other routine sampling and release points in the process of field oil production,and take precautions in advance,so as to inform field workers that they must pay attention to preventing the occurrence of hydrogen sulfide poisoning incidents.
