摘　　要：在对各种连续分层压裂工艺特点进行分析的基础上,重点对三种连续分层压裂工艺在国内的技术成熟度进行了探讨。认为机械封隔分层压裂在直井连续分层压裂工艺中仍占有主导地位,并且实现了连续分压8段的突破;连续油管分层压裂工艺将伴随着国内连续油管压裂技术水平和配套设备的发展而大规模应用;套管滑套(TAP)完井分层压裂工艺虽然具有先进的设计理念,但是目前仍处于探索试验阶段。Based on analysis of every kind of continuously layered fracturing technologies in vertical wells,it is focus on discussing the maturity of three types of continuously layered fracturing technologies in domestic.It is thought that the mechanical isolation fracturing in vertical well is still dominant in continuously layered fracture,and continuously fracture to 8 sections in a single operation has been made true.The continuously layered fracturing tech will be applied at great scale with development of the coiled-tubing layered fracturing and matching equipment.TAP(trace produce) completion layered fracturing is in testing and questing stage,although it has advanced design idea.
