天然气压缩因子计算方法
摘要：
本发明公开了一种天然气压缩因子计算方法，其特征在于：包括如下步骤：1)确定管道内的天然气气质；2)在管道内采样得到所述天然气气质的气质温度t和气质压力p，其中t的范围为0℃～60℃，p的范围为50KPa～4000KPa；3)根据公式z＝s1t2+s2pt+s3t+s4p+c得到天然气压缩因子z，其中s4是由所述天然气气质决定的参量，c是常数，s1＝A1s4+B1，s2＝A2s4+B2，s3＝A3s4+B3，其中A1、B1、A2、B2、A3、B3均为常数。
摘要（英）：

The invention discloses a natural gas compression factor calculation method. The method is characterized by including the following steps that firstly, natural gas quality in a pipeline is determined; secondly, quality temperature t and quality pressure p of the natural gas quality are obtained through sampling in the pipeline, wherein t ranges from 0 DEG C to 60 DEG C and p ranges from 50 KPa to 4000 KPa; thirdly, a natural gas compression factor z is obtained according to the formula that z equals to s1t2 plus s2pt plus s3t plus s4p plus c, wherein s4 is a parameter determined according to the natural gas quality, c is a constant, s1 equals to A1s4 plus B1, s2 equals to A2s4 plus B2, s3 equals to A3s4 plus B3, and A1, B1, A2, B2, A3 and B3 are all constants.
