摘　　要：水平井可以在不太厚的油层中增大钻井过油层范围,实现高速注、采,提高产量。有些水平井需要压裂,因此常常需要了解并控制人工裂缝形态、方位。通过微地震人工裂缝监测,研究已有的水平井压裂结果,特别是钻井水平段大体沿最大水平主应力方向的水平井压裂,了解压裂裂缝形成的机制及控制方式。通过比较,进一步提高水平井钻井水平及控缝理论。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 flooding and oil extraction and improving production. Some horizontal wells need fracturing, 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 drilling 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 .
