京253井位于华北油田京11断块上，人工裂缝方位、形态同时受到应力、构造、介质间断面影响，又进行了喷砂射孔，影响因素复杂。初始人工裂缝方位为北北东向，偏离区域最大水平主应力方向，区域最大水平主应力方向约为北东60 °，随后发生转向，趋于最大水平主应力方向及等高线法向方向。近井沿喷砂射孔方向也存在明显的微地震排列痕迹,研究京253井人工裂缝方位、形态具有典型意义。

Well J-253 is located in the J-11 fault block of North China oil field. The direction and geometry size of hydraulic fracture are affected by the stress, geological structure and faults, as well as hydraulic sand blasting. The direction of the initial artifical fracture is at NNE, deviating from the direction of the maximum herizontal principal stress. Then it turns to the direction of the maximum horizontal principal stress and normal direction of contour. Moreover, there are significant fissures lined around the well. It has typical significance to study the artifical fracture direction and geometry of Well J-253.
