油田有效分层注水是提高采收率的手段之一,而水井封隔器是实现这一手段的关键工具。由于套变井的井况较差,对封隔器的性能要求也较高。为了提高注水质量及密封性能,我们设计了K341-95小直径注水封隔器,介绍了其结构、工作原理以及应用情况,它不仅能够满足这种井的各种井况,而且该封隔器的密封性能及解封性能比较稳定。因此,该技术值得进一步推广应用。
Well-stratified waterflooding in oilfields is one of the ways to improve oil recovery, and well packers are key tools to achieve this. Due to poor casing condition, the performance requirements of the packer are also higher. In order to improve the water injection quality and sealing performance, we designed the K341-95 small-diameter water-filled packer, introduced its structure, working principle and application situation, it can not only meet various well conditions of this well, and the packer The sealing performance and unsealing performance is relatively stable. Therefore, the technology deserves further promotion and application.
