Induction crack, the azimuth that this pair induces crack then represents the direction of maximum horizontal principal stress.Obtain maximum horizontal master
The direction of stress is the important content for carrying out drilling hydraulic fracturing geostress survey.Existing acquisition maximum horizontal principal stress side
To method be mainly impression method, i.e., the trace height for inducing crack is stamped in the vulcanized rubber on its surface using stamp packing element
On, this method simple, intuitive, but also have disadvantages that mainly have：Time-consuming and laborious, inefficiency, each lower bore is only capable of obtaining
The directional information of 1-2 test point；The trace for being imprinted on stamp packing element surface is easy to be ground off by hole wall in drilling process；For
The larger drilling of stress value, it is also bigger due to inducing the stress that crack is opened again, it is difficult clearly to stamp and will induce
Crack trace.Above-mentioned several disadvantages influence experimental result in the case of the larger borehole conditions complexity of drilling depth tighter
Weight..
