Definitions
- the present invention relates to a method of drilling a wellbore in an earth formation using a drill string connected at the upper end thereof to a rotary drive and being provided with a drill bit.
- the invention further- more relates to a drill string for use in the method.
- a frequently encountered problem during drilling of a wellbore is sticking of the drill string in the wellbore. Such sticking can be, for example, due to differential sticking of drill string joints to the wellbore wall as a result of a pressure difference between the drilling fluid pressure in the wellbore and the pressure of earth formation fluid present in the pores of the formation. The problem is more frequently encountered in depleted oil/gas reservoirs where the pore pressure has decreased significantly.
- Each coupler is operable in an engaged mode in which the coupler transmits rotation between the two drill string sections interconnected by the coupler, and a disengaged mode in which the couplers allows free rotation of the two drill string sections interconnected by the coupler relative to each other about the longitudinal axis of the drill string.
- coupler 10 transmits rotation from section 18 to section 20
- coupler 12 transmits rotation from section 20 to section 22
- coupler 14 transmits rotation from section 22 to section 24
- coupler 16 transmits rotation from section 24 to section 26.
- each coupler 10, 12, 14, 16 is in the engaged mode.
- the fluid pump is operated to induce the first pressure variation to the column of fluid.
- the control system of coupler 10 responses so as to switch the coupler 10 to the disengaged mode, while the other couplers remain in the engaged mode.
- the rotary table 7 is then rotated, and as a result drill string section 18 is rotated due to the fact that only a limited amount of torque is needed to free drill string section 18 when compared to the torque which would be needed to free the entire drill string 1.
- the pump is operated to produce again the first pressure variation to the fluid column thereby inducing the control system of coupler 10 to switch the coupler 10 back to the engaged mode.
- the pump is operated to produce the second pressure variation in the fluid column.
- the control system of coupler 12 responses so as to switch the coupler 12 to the disengaged mode, while the other couplers remain in the engaged mode.
- the rotary table 7 is then rotated, and as a result drill string sections 18 and 20 are simultaneously rotated. It is thereby relevant to note that no differential sticking of drill string section 18 has occurred in the short period of time between engaging coupler 10 and disengaging coupler 12.
- the pump is operated to produce again the second pressure variation to the fluid column thereby inducing the control system of coupler 12 to switch the coupler 12 back to the engaged mode.
- the pump is operated to produce the third pressure variation in the fluid column.
- the control system of coupler 14 responses so as to switch the coupler 14 to the disengaged mode, while the other couplers remain in the engaged mode.
- the rotary table 7 is then rotated, and as a result drill string sections 18, 20 and 22 are simultaneously rotated. No differential sticking of drill string sections 18 and 20 has occurred in the short period of time between engaging coupler 12 and disengaging coupler 14.
- the pump is operated to produce again the fourth pressure variation to the fluid column thereby inducing the control system of coupler 16 to switch the coupler 16 back to the engaged mode.
- the rotary table 7 is then rotated, and as a result the entire drill string 1 is rotated. In this manner the drill string 1 has been freed from differential sticking in a stepwise manner .
