| 摘 要： | 双管注水技术的生产安全控制是其应用于海上油田的一大技术瓶颈,为此开展了同心双管注水管柱安全控制工具的研制。试制完成的海上双管注水单管双控安全阀可以达到同时对双管内外注水空间起到安全控制的作用,满足海上安全生产的要求。目前已在10口井中成功应用,大幅提高了一级两段分注井层段的合格率,对实现海上油田＂精细注水＂具有重要意义。

| Abstract: | When double string injection technology was used on offshore wells the safety control turned out to big problem to be solved.A safety control device was developed.After design and improvement,the double controllable safety valve was developed for double string water injection in offshore oilfield.It can control the safety of both inner center space and outer annulus space.This can meet the safety production requirement for the offshore oilfield.By now it has been successfully used in 10 wells.The one grade two sections block efficiency is improved greatly and it has an important significance in offshore oilfield water injection. |
