目前国内在线含水分析仪价格昂贵,不适合原油集输处理生产情况。为了替代目前在用的以质量流量计为主的原油计量设备,我们进行了一种在线密度计量装置的初步实验,通过对竖直管路中高低两点压力的测量,根据公式:p=ρgH求得管路中混合原油的密度,通过计算的方法得出混合原油中的含水率。这种装置不受液量和原油物性的限制,适用范围可以在站内,也可在单井,具有很好的开发潜力。 At present, the domestic online water analyzer is expensive and not suitable for the production and distribution of crude oil. In order to replace the existing mass flowmeter-based crude oil metering equipment, we conducted a preliminary experiment of the on-line density measurement device. Through the measurement of the pressure at two points in the vertical pipeline, according to the formula: p = ρgH The density of the mixed crude oil in the pipeline is obtained, and the water content in the mixed crude oil is obtained by calculation. This device is not limited by the amount of liquid and crude oil properties, the scope of application can be in the station, but also in a single well, has good development potential.
