Definitions

  • the present invention relates generally to drilling. More specifically, but not by way of limitation, embodiments relate to controlling the direction of boreholes drilled in earthen formations.
  • embodiments relate to controlling the direction of boreholes drilled in earthen formations.
  • it is sometimes desirable to be able to vary and control the direction of drilling for example to direct the borehole towards a desired target, or control the direction horizontally within an area containing hydrocarbons once the target has been reached. It may also be desirable to correct for deviations from the desired direction when drilling a straight hole, or to control the direction of the hole to avoid obstacles.
  • a borehole may be drilled so as to intercept a particular subterranean-formation at a particular location.
  • a drilling trajectory through the earth formation may be pre-planned and the drilling system may be controlled to conform to the trajectory.
  • an objective for the borehole may be determined and the progress of the borehole being drilled in the earth formation may be monitored during the drilling process and steps may be taken to ensure the borehole attains the target objective.
  • operation of the drill system may be controlled to provide for economic drilling, which may comprise drilling so as to bore through the earth formation as quickly as possible, drilling so as to reduce bit wear, drilling so as to achieve optimal drilling through the earth formation and optimal bit wear and/or the like.
  • Directional drilling is the intentional deviation of the wellbore from the path it would naturally take. In other words, directional drilling is the steering of the drill string so that it travels in a desired direction.
  • Directional drilling is advantageous in offshore drilling because it enables many wells to be drilled from a single platform.
  • Directional drilling also enables horizontal drilling through a reservoir.
  • Horizontal drilling enables a longer length of the wellbore to traverse the reservoir, which increases the production rate from the well.
  • a directional drilling system may also be used in vertical drilling operation as well. Often the drill bit will veer off of a planned drilling trajectory because of the unpredictable nature of the formations being penetrated or the varying forces that the drill bit experiences. When such a deviation occurs, a directional drilling system may be used to put the drill bit back on course.
  • the monitoring process for directional drilling of the borehole may include determining the location of the drill bit in the earth formation, determining an orientation of the drill bit in the earth formation, determining a weight-on-bit of the drilling system, determining a speed of drilling through the earth formation, determining properties of the earth formation being drilled, determining properties of a subterranean formation surrounding the drill bit, looking forward to ascertain properties of formations ahead of the drill bit, seismic analysis of the earth formation, determining properties of reservoirs etc. proximal to the drill bit, measuring pressure, temperature and/or the like in the borehole and/or surrounding the borehole and/or the like.
  • any process for directional drilling of a borehole whether following a pre-planned trajectory, monitoring the drilling process and/or the drilling conditions and/or the like, it is necessary to be able to steer the drilling system.
  • Forces which act on the drill bit during a drilling operation include gravity, torque developed by the bit, the end load applied to the bit, and the bending moment from the drill assembly. These forces together with the type of strata being drilled and the inclination of the strata to the bore hole may create a complex interactive system of forces during the drilling process.
  • Known methods of directional drilling include the use of a rotary steerable system ("RSS").
  • RSS rotary steerable system
  • the drill string is rotated from the surface, and downhole devices cause the drill bit to drill in the desired direction.
  • Rotating the drill string greatly reduces the occurrences of the drill string getting hung up or stuck during drilling.
  • Rotary steerable drilling systems for drilling deviated boreholes into the earth may be generally classified as either "point-the-bit” systems or "push-the-bit” systems.
  • the axis of rotation of the drill bit is deviated from the local axis of the bottomhole assembly ("BHA”) in the general direction of the new hole.
  • BHA bottomhole assembly
  • the hole is propagated in accordance with the customary three-point geometry defined by upper and lower stabilizer touch points and the drill bit.
  • the angle of deviation of the drill bit axis coupled with a finite distance between the drill bit and lower stabilizer results in the non-collinear condition required for a curve to be generated.
  • this may be achieved including a fixed bend at a point in the BHA close to the lower stabilizer or a flexure of the drill bit drive shaft distributed between the upper and lower stabilizer.
  • the drill bit is not required to cut sideways because the bit axis is continually rotated in the direction of the curved hole. Examples of point-the-bit type rotary steerable systems, and how they operate are described in U.S. Patent Application Publication Nos.
  • Known forms of RSS are provided with a "counter rotating" mechanism which rotates in the opposite direction of the drill string rotation.
  • the counter rotation occurs at the same speed as the drill string rotation so that the counter rotating section maintains the same angular position relative to the inside of the borehole. Because the counter rotating section does not rotate with respect to the borehole, it is often called “geo-stationary” by those skilled in the art. In this disclosure, no distinction is made between the terms “counter rotating” and “geo-stationary.”
  • a push-the-bit system typically uses either an internal or an external counter- rotation stabilizer. The counter-rotation stabilizer remains at a fixed angle (or geostationary) with respect to the borehole wall.
  • an actuator presses a pad against the borehole wall in the opposite direction from the desired deviation. The result is that the drill bit is pushed in the desired direction.
  • the force generated by the actuators/pads is balanced by the force to bend the bottomhole assembly, and the force is reacted through the actuators/pads on the opposite side of the bottomhole assembly and the reaction force acts on the cutters of the drill bit, thus steering the hole.
  • the force from the pads/actuators may be large enough to erode the formation where the system is applied.
  • the SchlumbergerTM PowerdriveTM system uses three pads arranged around a section of the bottomhole assembly to be synchronously deployed from the bottomhole assembly to push the bit in a direction and steer the borehole being drilled.
  • the pads are mounted close, in a range of 1 - 4 ft behind the bit and are powered/actuated by a stream of mud taken from the circulation fluid.
  • the weight-on-bit provided by the drilling system or a wedge or the like may be used to orient the drilling system in the borehole.
  • While system and methods for applying a force against the borehole wall and using reaction forces to push the drill bit in a certain direction or displacement of the bit to drill in a desired direction may be used with drilling systems including a rotary drilling system, the systems and methods may have disadvantages.
  • such systems and methods may require application of large forces on the borehole wall to bend the drill-string and/or orient the drill bit in the borehole; such forces may be of the order of 5 kN or more, that may require large/complicated downhole motors or the like to be generated.
  • many systems and methods may use repeatedly thrusting of pads/actuator outwards into the borehole wall as the bottomhole assembly rotates to generate the reaction forces to push the drill bit, which may require complex/expensive/high maintenance synchronizing systems, complex control systems and/or the like.
  • Drill bits are known to "dance" or clatter around in a borehole in an unpredictable or even random manner.
  • the dancing may involve motion of the drill bit in the borehole and/or random variations of reaction forces between the drill bit and an inner-wall of the borehole.
  • This stochastic movement and/or stochastic reactionary force interaction is generally non-deterministic in that a current state does not fully determine its next state.
  • Point-the-bit and push-the-bit techniques are used to force a drill bit into a particular direction and overcome the tendency for the drill bit to stochastically clatter. These techniques ignore the stochastic dance a drill bit is likely to make in the absence of directed forces.
  • a drill bit for drilling a cavity/borehole may include a chassis or the like, a plurality of gauge pad sets, and at least one gauge pad structure.
  • the chassis may be configured to rotate about an axis.
  • the plurality of gauge pad sets may each include at least one gauge pad.

  • Fig. 2D chassis 150 has rotated ninety degrees from Fig. 1OC in the direction shown by arrow 1001. Now gauge pad D is fully extended when it faces the absolute radial direction indicated by arrow 1005. Gauge pad B meanwhile is fully retracted. Gauge pad A is in the process of being extended, and gauge pad C is in the process of being retracted. The process may then be repeated as chassis 150 rotates another 90 degrees presenting gauge pad A toward the absolute radial direction indicated by arrow 1005.
  • Such systems and methods may be used with any number of gauge pads so as to direct the drill in a direction opposing arrow 1005, possibly even in multiple different directions over a varied depth.
  • gauge pads 111 may be extended/retracted prior to or after the positions shown in Figs. 10A- 1OD to achieve movement away from the direction shown by arrow 1005.
  • Automated systems such as control system 170 may determine the steering tool face offset necessary to achieve the desired directional drilling and modify instructions to the gauge pad structures controlling the movement of gauge pads 111 based thereon. Such automated systems may monitor the effectiveness of a determined tool face offset, and adjust as necessary to continue directional drilling. These systems may be able to differentiate between "noise" fluctuations and real changes.
  • Fig. 11 it will be recognized how repeating the process detailed above can result in a directional bore hole. Also recognizable is how the absolute radial direction may slowly change as the angle of bore hole changes due to directional drilling. If directional operation continues, then the bore hole may continue to "curve.” Alternatively, once a certain angle of bore hole has been achieved, straight drilling may recommence by allowing the gauge pad structures in the chassis to equalize the extension of all gauge pads, assisting substantially symmetrical drilling around the perimeter of the chassis and straight bore hole drilling in the then current direction. Additionally, cyclical variation of the gauge pads may also allow for straighter drilling, especially when boundaries between different earthen formations (particularly steeply dipping formations) are crossed.
  • stabilizers positioned above the drill bit in the drill string could utilize systems and methods of the invention to provide variable gauge stabilization at relevant portions of the drill string. Such biasing could also at least assist in steering of the drill string and/or drill bit.
  • stand drill bits could be utilized with variable gauge bad subcomponents employed "behind" the standard drill bits to provide the advantages of the invention in aftermarket tooling for conventional bits.
