2019-11-15 13:35:27      点击:

针对油田注入高压二氧化碳测量做如下改进:


1.一体化结构设计,充分考虑CO2介质流动状态宜相变和后期保温等影响及安装空间限制卸、维护需求。The following improvements are made to the measurement of high pressure carbon dioxide injection in oil fields。


2.V锥体设有防V型锥体脱落的安全措施,针对高压Co2介质测量条件及环境,特殊设计了保证V锥体脱落的双管内衬和环形支撑技术,确保V型锥在高压下的整体安全。


The integrated structure design takes fully into account the influence of the appropriate phase transition and post-insulation of the CO2 medium flow state and the installation  space restricted unloading and maintenance requirements.The V cone is equipped with safety measures to prevent the V-shaped cone from falling off. For the high pressure Co2 medium measurement conditions and environment, a double-tube lining and circular support technology to ensure the V cone shedding is specially designed to ensure the overall safety of the V-shaped cone under high pressure.
3.取压方式采用多孔、环室取压方式,以保证V型锥体的高精度。


The pressure extraction method uses porous and circular pressure extraction methods to ensure the high accuracy of the V-shaped cone.


4.将各种工况下二氧化碳等127种介质的不同相态、不同温度和不同压力状态下介质的密度、粘度和压缩系数数据库,整体集成固化于流量变送器存储芯片中,确保温度、压力补偿准确。


The database of density, viscosity, and compression coefficient of 127 kinds of media such as carbon dioxide under various working conditions is integrated and solidified into the flow transmitter storage chip to ensure temperature and pressure compensation. accurate.


5.参数配置功能,使用电脑工程助手软件可设置显示信息、配置V型锥流量参数和20点流出系数等参数。


Parameter configuration function, using computer engineering assistant software can set display information, configuration V-shaped cone flow parameters and 20 poin outflow factors and other parameters.
6.直接测量质量流量和体积流量。


Direct measurement of mass flow and volume flow.


7.现场就地显示并远传体积和质量流量,并可进行故障自诊断。


On site, the volume and mass flow are displayed and transmitted far away, and self-diagnosis can be performed.


8.每台仪表出厂前确保100%检测和打压。


Ensure 100 % detection and suppression of each instrument before it is delivered.
