摘　　要：阐述了转向压裂技术原理,分析了重复压裂转向理论,研究了转向裂缝的造新缝条件,得出了准东油田产生新缝判断准则,给出了转向压裂井层优选原则,在井层优选原则的基础上,开展了10口井现场试验,取得了很好的应用效果,提出了转向压裂技术是准东油田低渗油藏高含水期一种新的重复压裂技术。The work principle of turnaround fracture technology is introduced. The theory of turnaround re-fracture is analyzed. The conditions of creating new fracture are studied. The criteria for judging the creation of new fracture in Zhundong oilfield is obtained. At the same time, the rules for optimum selection of turnaround fractured well layer are also given ,which has been undertaken in field trials for ten wells and achieves good effects. This turnaround fracture technology is considered as a new re-fracture technology with low permeability and high containing water reservoir for Zhundong oilfield.
