Abstract: This paper analyzes the necessity for installation of wellhead safety monitoring system for Yakela Condensate Gasfield, and describes the composition of the wellhead safety monitoring system and its corresponding video monitoring, remote detection parameters, remote shut-in, high/low pressure automatic shut-in functions, highlighting the system configuration i.e. critical data detection, data acquisition equipment, communication mode, hydraulic control cabinet, video monitoring, and auxiliary facilities. The system has been widely used in Yakela Condensate Gasfield, which not only improves the safety management level of well control, but also realizes downsizing for efficiency.
