随着我国经济的不断发展,我国对于套损分层注水井的应用越来越重视,而套损分层注水井中对常规小直径封隔器的应用非常广泛,但是常规小直径封隔器在实际的应用过程中经常会出现拔出困难的情况,这样就造成了进一步细分的难度,通过研制对抱卡式小直径逐级解封封隔器进行了应用。对抱卡式小直径逐级解封封隔器的研制应用,能够保证对小直径封隔器逐级解封功能的有效实现,进而实现对套损分层注水井精细细分的要求。
With the continuous development of economy in our country, more and more attention has been paid to the application of stratified injection wells in our country. However, the application of conventional small diameter packer in stratified injection straws is very extensive. However, conventional small diameter packer In the actual application process often appear difficult to pull out the situation, resulting in further subdivision of the difficulty, through the development of the card-type small diameter step by step unwinding packers have been applied. The development and application of the pallet-type small-diameter step-up and seal-off packer can ensure the effective realization of step-by-step lift-off of the small-diameter packer and further realize the requirement of subdivision and fine-grading injection well.
