- 摘要:
- 本文结合大庆油田天然气加工装置的给排水检查井的冻害现状，对冻害规律及冻害机理进行了分析，对处于不同水文地质条件和使用条件的检查井，通过增设断水活性隔离层、采用双向对称的正圆锥形井体、地基换土处理等防范措施进行了改造。经5年的使用证明，防冻效果很好，而且节约了大量建设资金。
This paper analyzes the pattern and mechanism of the freezing hazard to the inspection wells for water supplying and draining for the natural gas processing equipments in Daqing Oil Field.The wells under different hydrogeological conditions and application conditions were transformed by taking the preventive measures. It is shown after five - year applications that these measures are excellent in preventing freezing and save substantial construction cost.1995,5(5): 18-20 收稿日期：1995-4-21分类号：TE45
