Analysis of Transmission Error in Jiannan Gas Field and Its Prevention Measures

摘要: 建南气田输差率控制水平总体上达到Ⅱ类采气厂标准，2017年平均输差率为1.89%，但是南北集输管网输差差异较大。为了较好地控制输差，获得准确产气量，从集输管网和计量输差等方面进行输差分析，并提出采用排水、加强计量等措施降低输差，以期为建南气田的生产提供准确的数据。

Abstract: The control level of the transmission error rate in Jiannan Gas Field has generally reached the standard of Class II gas production plant. The average transmission error rate was 1.89% in 2017, but the transmission error between the north and south gathering pipeline networks was quite different. In order to better control the transmission error and obtain accurate gas production, the transmission error analysis is conducted from the aspects of the gathering pipeline network and the metering error, and it is proposed to use drainage and strengthen metering to reduce the error for the purpose of providing accurate data for the production in Jiannan Gas Field.
