众所周知,天然气作为一种清洁高效能源在全球范围内已成共识,天然气在世界能源结构中的地位不断上升,但是天然气在开发过程中又具有原始地层压力高、有毒有害气体含量高、初期测试产量高等“三高”特点,对气井进行测试作业也随之带来高风险。本文通过对气井测试作业过程中易形成安全隐患的重点、难点进行影响因素分析,并结合具体实践提出了构建多重安全屏障的方法,确保气井测试作业安全。
As we all know, as a clean and efficient energy source of natural gas has been agreed on a global scale, the status of natural gas in the world energy structure continues to rise, but natural gas in the development process has the original formation pressure is high, toxic and harmful gas content is high, initial test output Higher “three high ” characteristics, the gas well test operations also will bring high risk. In this paper, we analyze the factors that make it easy to form the potential safety hazard during gas well test, and put forward the method of constructing multiple safety barriers according to the concrete practice to ensure the safety of gas well test.
