高含硫气田废水回注黄龙3井数据传输方案

Data transmission plan optimization of Huanglong-3 waste water reinjection well in high sour gas field

根据环境影响报告书的要求,罗家寨、滚子坪气田工业生产废水及检修废水经处置达标后需经回注井回注地层,罗家寨、滚子坪气田项目废水起排点天然气处理厂距离废水回注井的地理位置较远,为了能够有效地对废水回注井及回注管线压力、流量和温度数据进行实时监测,并在废水回注过程中意外事故发生时能够得到及时的预警,废水回注井井口数据传输方案设计的可靠性及可行性变得非常重要。故从设计角度出发,阐述了罗家寨、滚子坪气田废水回注井多种数据传输可行性设计方案,经过对比分析及现场测试,推荐GPRS无线数据传输为本气田废水回注数据传输的最佳方案。

According to EIA report requirements, the industrial and overhaul waste water of Luojiazhai and Gunziping shall be reinjected into ground via reinjection well after treatment. The distance between natural gas treatment plant of Luojiazhai or Gunziping gas field to reinjeetion well is far away, so the reliability ＆ feasibility of reinjection wellhead data transmission design is very critical for real-time monitoring of pressure, temperature and flow in reinjection well pipeline as well as alarming on time when accident happens during reinjection. From the point of design, this paper specified the feasible scenarios of reinjection wellhead data transmission. GPRS wireless data transmission should be the best scenario for this project through comparisons, which might provide some reference for other similar data transmission projects.
