Definitions
- the present invention relates to a method of conducting a borehole.
- the drill string motor which is mounted to the surface, rotates at a constant speed of about 50-150 rpm.
- the friction produced between the drilling tool and the bottom of the well, or between the rods and the wall of the well can cause slowing down or even periodic stops of the tool.
- the motor continues to rotate at one end of the drill string, the latter tends to twist around its longitudinal axis until the force exerted is greater than the friction effect braking the tool.
- the drill string relaxes and the tool starts to rotate again, reaching peak rotational speeds of the order of 150 to 400 revolutions / minute.
- contact between the lining and the wall of the well occurs quite frequently.
- the behavior of the tool has a significant effect on the progress of the drilling.
- the master driller be warned of the periodic instabilities of the tool's rotation speed so that he can modify the drilling parameters - engine rotation speed, weight applied to the tool or the mud flow rate - and thus ensure optimal drilling.
- the present invention therefore relates to a method of conducting a borehole which makes it possible to provide a user, in a simple manner, with data on the state of rotation of the rod.
- FIG. 1 is a schematic sectional view of a drilling assembly
- - Figure 2 is a flow diagram of certain steps of the method of the invention.
- - Figures 3A, 3B and 4 each show pairs of torque and speed curves.
- a drilling assembly comprises a mast 10 provided, in a manner known per se, with a hook 12 to which is suspended a drill string, generally represented at 14.
- the drill string 14 comprises a drilling tool 16, drill rods 18 and drill rods 20 forming an assembly called a drill string.
- the drill string 14 is rotated by a rotation table 22. Any other device can be used.
- the rotation table 22 is provided with a rotation speed sensor 24 and a torque sensor 26 applied to the drill string 14.
- a result of less than 10% implies a small variation in torque which makes it possible to deduce therefrom that there is no instability in the speed of rotation of the lining.
- the method makes it possible to signal to the master driller that he can maintain the drilling parameters.
- the theoretical period P ⁇ . h is a characteristic of the packing used. It is calculated from the natural modes of vibration in torsion of the lining. As there are several eigen modes of vibration, it follows that there are several values for P th that we can call ' p th2' We therefore carry out a comparison of the current P value with each of the predetermined theoretical values to see if the P value is in a range between 0.8 and 1.2 times the value of one of the theoretical values Pt '
- FIGS. 3A and 3B are two pairs of curves, at a different time scale, of the variation of the torque C and of the speed of rotation of the tool VR over time.
- the measurements were carried out by a recording device placed at the bottom of the well. These measurements make it possible to visualize the relationship between the torque and the speed of rotation and to confirm that this relationship corresponds to the hypotheses on which the method according to the present invention is based.
- Figure 4 shows in more detail the variation of the torque and the rotation speed.
