SUPERNORMAL FRACTURING TECHNOLOGY FOR INCREASING PROPPED FRACTURE WIDTH

提高缝宽的超常规压裂是解决提高人工裂缝的支撑缝宽来提高其导流能力问题的工艺技术,它整合了常规压裂工艺技术和端部脱砂压裂工艺技术,满足低渗储层对人工裂缝导流能力的需要。文中从人工裂缝导流能力影响因素、提高支撑缝宽的理论基础、现场工艺应用三个方面介绍用于提高缝宽的超常规压裂工艺技术,旨在提高低渗储层压裂改造的工艺水平和施工效果,为勘探开发和油气井增储上产提供强有力的手段。

Supernormal fracturing technology can improve flow conductivity of fracture by increasing propped fracture width.It integrate normal fracturing technique and tip sandout fracturing technique.It can meet the requirement of low permeability formation to fracture conductivity.The article introduces the supernormal fracturing technology used for increasing fracture width from three aspects which are the affecting factors of created fracture conductivity,the theory of increasing propped fracture width and the field application.
