- 摘要:
- 井口安全控制系统的稳定可靠是油田气井安全生产的保障。现场应用表明，基于电-液工作原理的井口安全控制系统故障多源于自控部分，为了从本质上提高系统的可靠性，需对现有系统的自控部分进行分析和优化。分析了塔里木油田井口安全控制系统的工作原理及特点；针对系统自控部分现状，从自动化架构、安装接线、运行环境等因素，指出了系统自控部分现存的问题；提出了自控部分优化方案和整改建议。控制柜应进行通风散热、减振等设计，采用改进型高度集成化的自动化架构（冗余控制器）等研究结果可为油田高压油气井井口安全控制系统优化改造和后续采购提供参考依据。
The stable and reliable wellhead safety control system is an important guarantee for safe production of gas wells in oilfield. Field application shows that most of failures in electric-hydraulic wellhead safety control system are resulted from automatic control components. In order to improve the reliability of the system in essence, it is necessary to analyze and optimize automatic control components of the existing system. Analyzed are the working principle and characteristics of wellhead safety control system in Tarim Oilfield, identified are problems existing in automatic control components of the system and proposed are specific optimization scheme and such corrective recommendation as addition of ventilation and heat dissipation and vibration attenuation design in control cabinet, application of modified highly integrated automation architecture (such as redundant controller), which can provide valuable reference for optimization and modification and subsequent procurement of high-pressure oil and gas wellhead safety control system.
