摘　　要：在水力压裂过程中,裂缝会沿着垂直方向上延伸,当裂缝超出生产层而进入隔层时会影响水力压裂效果。为了将裂缝高度控制在油气层内,研究了岩石物质特性、施工参数、地层应力差和裂缝上下末端阻抗值对缝高的影响,并分析了人工隔层控制缝高基本原理和对转向剂性能要求、压裂工艺与应用范围,同时也提出了控制缝高技术的研究内容与发展趋势。Fracture will extend around perpendicular direction during hydraulic fracturing.The effect of hydraulic fracturing will be influenced when the fracture exceed production layer and enter interlayer.In order to command fracture height to extend in oil and gas layers,this paper studies the effect of petrophysical property,construction parameters,stratum stress and tip resistance of fracture top and bottom on the fracture height.It analyzes basic principium of artificial interlayer commanding fracture height and the requirement for partition,technology of hydraulic fracturing and application range of partition,at the same time,proposes research contents of technology of fracture height containment and development current.
