井口称重式计量系统在油田的应用

The Application of Wellhead Weighing Metering System in Oilfield

自提出将"罐储车运"的原油输送方式改造成管道输送的工艺,单井计量就成为实现管输的关键性技术。井口称重式计量系统主要由单井入口管路、多路阀、称重传感器、左位置传感器、右位置传感器、罐体、油气分离器、单井气出口管路、集料斗、分布器、翻斗、浮子调节器、单井出口管路、单井汇流出口管路等组成。计量系统设置了一个全自动多路阀,最多可以接入30口单井,通过计算机实现单井的自动切换,连续测量每个单井的产液量。位置传感器检测翻斗的状态,自动检测、记录、打印、显示各单井的生产运行参数,可实现连续自动量油。该计量系统能较好地解决高黏度稠油和低油气比油井的单井计量问题,同时也能满足稀油和高油气比油井的单井计量,具有广泛的适用性。

Put forward the ＆quot;car tank storage transport＆quot; converted into pipeline technology, single- well measurement will become a key technology for pipeline transporting. Wellhead weighing metering system is mainly composed of single well entry line, multichannel valve, weighing sensor, left or right position sensor, tanks, oil and gas separator, single well gas export pipeline, hopper, distributor, skip, float controller, single well pipeline, single well flow export pipeline, etc. Metering system is added a full automatic multi-channel valve on the device, can access to ≤30 single-well respectively, through the computer to realize automatic switching of single well, continuous measurement of each single well pro-duced fluid volume, skip position sensor, automatic detection, recording, printing, dis-play operation parameters of each single well production,which can realize continuous auto-matic metering oil. The metering system can well solve the high viscosity of heavy oil and low oil and gas ratio single well oil well measurement problem,also can meet the thin oil and high oil and gas than single well oil well measurement at the same time,and has wide applica-bility.
