摘要:: 激光甲烷探测器相对于催化燃烧式和点红外式可燃气探测器具有灵敏性高、反应时间短、覆盖面广等特点。本文通过对三种类型的探测器现场应用情况进行实地调研，采用现场试验的方式探究了利用激光甲烷探测器和点红外式探测器构建可燃气探测系统新模式的可行性。现场试验表明，新的可燃气探测系统相对于原设计系统可以减少现场可燃气探测器数量约30%，同时具有更高的灵敏度、准确度和覆盖率，降低了海洋油气生产装置因天然气泄漏带来的风险和隐患，对海洋油气生产装置可燃气探测技术升级和标准的制定具有重要意义。

Abstract:: Compared with catalytic combustion and point infrared combustible gas detectors, laser methane detector has the characteristics of high sensitivity, short reaction time and wide coverage. Through the field investigation of the field application of three types of detectors, this paper explores the feasibility of using laser methane detector and point infrared detector to build a new model of combustible gas detection system. The field test shows that the new combustible gas detection system can reduce the number of on-site combustible gas detectors by about 30% compared with the original design system. At the same time, it has higher sensitivity, accuracy and coverage, and reduces the risks and hidden dangers caused by natural gas leakage in offshore oil and gas production units. It is of great significance to the upgrading of combustible gas detection technology and the formulation of standards for offshore oil and gas production units.
