Definitions

  • the invention relates to the field of drilling, and more particularly to a rotary guiding device that controls drilling guidance.
  • directional drilling In order to obtain natural resources storaged underground, drilling exploration is required. In many cases, the wellbore and the derrick are not aligned, but need to form a certain offset or bend. This process of forming horizontal or vertical offsets or other types of complex holes is called directional drilling. In the process of directional drilling, the direction control of the drill bit is called guidance. Modern directional drilling has two types: sliding guidance and rotary guidance. The drill string does not rotate when sliding guiding drilling; the bottom hole power drill (turbine drill, screw drill) drives the drill bit to rotate. The screw drilling tool and part of the drill string and the centralizer can only slide up and down against the well wall.
  • Rotary steerable drilling system is the rotary drive of the drill string, the drill string and the rotary guiding tool are rolled on the well wall, and the rolling friction resistance is small.

  • both the directional guidance and the push-oriented guidance have their own characteristics.
  • the slope of the directional guidance is relatively stable, which is less affected by the drilling pressure and formation conditions, but the limit value of the slope is low, and it is difficult to meet the requirements when a high build-up rate is required.
  • the slope of the push-oriented guidance is not stable, and it is greatly affected by the drilling pressure and formation conditions, when the drilling pressure is low and the hardness of the formation is appropriate, the slope is large, and the well trajectory can be quickly adjusted, however, the guiding ability is reduced when the soft formation is encountered.
