【摘要】：为了确保天然气贸易交接的公平、公正,在配气站中需设置实时在线的计量系统。新疆油田某天然气配气站早期建成的计量系统不满足现行国家计量标准对流量计直管段配置的要求,其计量数据造成气量结算、成本核算困难。基于国家相关标准要求,为了实现经济效益最大化,采用更为灵活的短管安装方式配置管道,并对原有工艺流程进行改造,既提高了流量计的测量上限,又避免了前端压力波动造成流量计准确度降低的问题。在改造过程中,充分利用原有的管路、设备、流量计等材料开发出配气站的备用计量管路,无需额外的设备购置费和改造费,节约费用约115×10~4元,同时为今后配气站增加负荷提供了计量空间。
[Abstract]:In order to ensure the fairness and fairness of the natural gas trade transfer, a real-time and online metering system should be set up in the gas distribution station. The metering system built in the early stage of a natural gas distribution station in Xinjiang Oilfield does not meet the requirements of the current national metering standards for the direct pipe configuration of the Flowmeter. The metering data result in the settlement of the gas volume and the cost accounting is difficult. In order to realize the maximum economic benefit, a more flexible short pipe installation method is adopted to configure the pipeline, and the original technological process is reformed to improve the measuring upper limit of the Flowmeter, based on the requirements of the relevant national standards. It also avoids the problem that the accuracy of the Flowmeter is reduced due to the pressure fluctuation of the front end. In the process of transformation, the spare metering pipeline of the gas distribution station is developed by fully utilizing the original pipe, equipment, Flowmeter and other materials, and the cost is saved about 115 脳 10 ~ (4) yuan without additional equipment purchase and renovation costs. At the same time, it provides metering space for increasing the load of gas distribution station in the future.
