Microseismic monitoring of Well J-253 in complicated construction

Zhao Xinhong,Che Hang,Luo Jiong

Strategic Study of CAE 2012, Volume 14, Issue 4,   Pages 12-15

Abstract:

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.
