- 摘要:
- 川东北气矿气水同产井污水量大，污水夹带气较多，井站臭味特别大，存在极大的安全、环保隐患。针对上述问题，陆续采取改进措施：污水罐和污水池的呼吸管埋地铺设改为架空铺设；污水罐呼吸管废气自然飘散改为放空燃烧；污水罐进液管由下进改为上进；改造污水罐进液管结构；新增污水罐进液口气液分离附加组件；污水罐出液管增设自动水封装置；污水泵改填料密封为机械密封；优化生产操作工艺和生产制度；严格污水装卸拉运管理及其他设计与安装上的技术改进。通过上述改进和近年雷13、雷14、七里25、七里025-X1井站的改造试运行，不仅生产运行平稳，“跑冒滴漏”显著减少，作业环境大为改善，检修次数和时间明显减少，每年节约检修费用约20万元，而且消除了原先低空弥漫的有害气体，员工健康状况和生产安全性有了极大的改善，井站周边居民普遍反映基本无臭味。气水同产井站恶臭治理成功，为同类型气水同产井地面集输系统装置工艺设计或大修设计提供了参考和技术借鉴。
Gas-water producing wells in Northeast Sichuan Gas Field are at a high potential risk in safety and environmental protection due to large amount of sewage entrained with plenty of gas and very stenchy well station. Aiming at the above-mentioned problems, a series of improvement measures have been taken one after the other. Through improvements and trial stimulation operation in Lei 13 and 14, Qili 25 and 25-X1 well stations in recent years, gas and water leakage has been remarkably reduced, operation environment has been significantly improved and well maintenance cost has been cut down by ¥0.2 million (RMB) annually. In addition, the harmful gas pervaded previously at a low-altitude has disappeared at present, staff health and safety have been greatly improved. Residents nearby the well stations also say that there is almost no stench anymore. Success in stench control for gas-water producing wells has provided a reference and technical support for similar ground gathering system design.
