乍得Ronier油田一期工程在实验电站天然气系统气密性过程中,立足现场实际情况,开创性地使用天然气作为介质、使用天然气压缩机为设备成功地完成了高压天然气系统的气密性试验。实验过程主要注意以下几个问题:1)做好安全措施并配备安全设备;2)检查天然气系统附件的完整性;3)使用空气压缩机吹扫天然气系统;4)使用空气压缩机试验压力到20Bar;5)氮气置换;6)天然气置换;7)使用天然气压缩机试验压力到27Bar;8)使用天然气压缩机试验压力到32Bar。乍得油田使用天然气实验天然气系统的成功,不仅节约了大量设备费用、节省了燃料费用,而且也为国内外同类项目开创了新的技术。
The first phase of the Ronier oilfield project in Chad succeeded in the gas-tightness test of high-pressure natural gas systems using natural gas compressors as equipment in the airtight process of the natural gas system of the experimental power plant, based on the actual situation in the field and pioneering the use of natural gas as a medium. The main points of the experiment are as follows: 1) Safety measures should be taken and safety equipment should be provided; 2) Check the integrity of natural gas system accessories; 3) Purge natural gas system with air compressor; 4) Use air compressor to test pressure to 20 Bar; 5) Nitrogen replacement; 6) Natural gas replacement; 7) Natural gas compressor test pressure to 27 Bar; 8) Natural gas compressor test pressure to 32 Bar. The success of Chad Oilfield’s use of natural gas to experiment with natural gas systems has not only saved significant equipment costs, saved fuel costs, but also created new technologies for similar projects both at home and abroad.
