摘　　要：重复压裂井在压裂过程中受前次压裂的影响 ,裂缝的起裂以及延伸方向取决于地应力场的变化。以真三轴试验为基础 ,对重复压裂裂缝破裂机理和裂缝延伸规律进行了研究 。To re-fractured wells influenced by previous treatment,initial seam and prolong directionof the gap are caused by change of stress field.Based on true three axial test,the paper studies the breakdown mechanism and gap principle caused by re-fracturing and analyses the possibility to create new seam and its requirement.
