摘　　要：阐述了转向压裂技术原理,介绍了转向剂的性能,分析了重复压裂转向理论,得出了自然转向和诱导转向的应力差值;在转向压裂工艺优化的基础上,开展了两口井现场试验,取得了很好的应用效果;提出了转向压裂技术是江苏油田低渗透油藏高含水期一种新的重复压裂技术。The principle and performance of turnaround fracture tech have been introduced and by analyzing repeat fracture turnaround theory, stress differences between natural and induced turnaround fracture is achieved. By the basement of optimizing this tech, experiments in two wells are conducted and good result is gained. It is pointed out that the turnaround tech is a new repeat fracture wa\ tor percolation and high containing water reservoir.
