单井油气计量系统主要由并联的大、小量程流量计和PLC控制器组成.实际计量过程中,根据流量大小,PLC按照量程要求设计的控制程序,自动切换为单独用小量程流量计、大量程流量计或组合用多台流量计,有效扩大流量计量的范围(量程比),满足油田计量分离器宽量程单井油、气产量准确计量要求,为了解油气井储层变化情况、分析油气井生产动态、指导油田开发方案的制定提供准确、可靠的生产数据.该方法主要用于油气田开发过程中多井集中计量系统,以及其他宽量程流量计量工程.

The hydrocarbon metering system for a single well was mainly composed of parallel large and small range flowmeters and PLC controller. In the actual measurement process, PLC controller controlled program according to design requirement and flow size. Hydrocarbon metering system could automatically switch to small range, wide range or the combination of both, which effectively expanded the scope of flow measurement (range ratio) and met the need in the accurately calculation of oil and gas. This system provided accurate and reliable production data about reservoir change, well production condition and hydrocarbon exploration scheme. The method was mainly used in oil and gas field development in the process of multi well concentrated metering system, and other wide range flow measurement engineering.
