摘要
随着国内油气井分层改造合层开采井数的逐渐增多。其分层改造方式逐渐增多。本文主要对以单向卡瓦式封隔器和无支撑式封隔器为主的分层改造合层开采管柱，从其可靠性方面进行分析对比，为油气井在机械分层改造合层开采时选择合理的分层改造管柱提供一定的依据。
Reliability of the tube string of separate-layer reformation and commingled recovery with unidirectional anchor-packers and no-support-packers is analyzed and contrasted in this article. It provides a basis for selection of reasonable separate-layer reformation tubing string of separate-layer reformation and commingled recovery of oil and gas wells.
