摘要
防漏堵漏所面临的最大问题就是地质情况的复杂性和不确定性,简单、方便、直观地实时监测漏失层,及时对地层压力、强度及漏失可能性做出评价和简单有效的应急措施成为解决问题的关键。随着勘探开发领域的扩展,井漏复杂程度增加,治理难度也在加大。为此,分析了现有的处理井漏技术,提出了现有的防漏堵漏技术还存在不少问题,无法完全满足防漏堵漏和保护储层的目的,还需要研发新的堵漏技术和设备以便应对越来越复杂的井漏事故,减少或消除由于井漏造成的复杂情况、时间的延误和重大经济损失。
The lost circulation is a kind of common phenomenon during drilling,with the expansion of exploration development domain,the lost circulation complex degree is increased,the treatment difficulty is also enlarging.This article analyzed the existing processing lost circulation technology and existent problems,the actual leak protection and sealing technology can't satisfy the requirement of protection reservoir completely.So,a new sealing technology and the equipment were developed in order to reduce complex lost circulation accident.
