Abstract
The horizontal well is a new format of oil production in the technology of drilles well development. It increases the range of drilling well crossing oil layer in a thin oil-bearing formation, carrying out high speed water flood i ng and oil extraction and improving production. Some horizontal wells need fracturin g, therefore the the shape and orientation of the man-made fracture is often expected to be understood and the controlled. The microseism monitoring of man-made fracture can understand the shape and orientation of fracturing fracture. By researching already fractured result of horizontal well, in particular the horizontal section of drilli ng well along the orientation of maximum horizontal principal stress, the forming mechanism and controlling pattern. Thus the drilling well level of horizontal well and controlling fracture theory can be improved.
