摘　　要：通过对重力式气液分离器的结构和工作原理的研究,确定影响其处理能力的关键因素主要为排气管尺寸和高度、液垫高度、钻井液的类型以及钻井液性能。结合油藏油气性质,计算出分离器的最大可处理量。采用井控模拟软件计算钻井液出井的放喷速度,综合评价气液分离器的工作能力。在钻井设计阶段,结合油藏及钻井工况,对气液分离器能力进行评估,为实际作业中进行井控处理提供理论依据,同时为钻机检验时气液分离器的评估提供技术指导。To define the influence features of gas separator,researches of separator＆#39;s structure and mechanism has to be done,combining properties of reservoir and taking flow rate of well control software which is calculated specifically,it is possible to evaluate main capability of gas separator.As the research of gas-liquid separation,some features such as gas pipe size and height,liquid column height,drilling mud type,mud properties are critical to the capability.During the well design,taking consideration of reservoir and drilling operation,evaluating the capability of separator just to direct well control and rig maintaining as well.
