Definitions
- An expandable device fixed to the front end of the guide element, has an external lateral surface which, in a state of rest, has a cross section smaller than that of the borehole and which is arranged to take, in a expanded state of the device, an immobilization support for said assembly against the wall of the borehole.
- the expandable device comprises selective actuation means, arranged to receive a pressurized fluid which causes expansion of the expandable device beyond a determined pressure of the fluid, and a valve arranged to automatically oppose an outlet of this fluid at a pressure determined outside said actuating means.
- a deflection channel is hollowed out in the guide element in extension of the internal space, upstream of the expandable device in said direction of advance.
- the deflection channel has a rear end coaxial with said internal space, a bottom and lateral sides which follow, from this rear end of the channel and in the direction of the expandable device, a direction inclined with respect to the longitudinal axis of the guide element, the bottom intersecting this axis.
- the channel extends until it opens completely from the guide element, on the other side of the longitudinal axis, at an angle relative to the above wall which is chosen for the deflected coring.
- the deflection channel has a cross section suitable for passing said corer guided by the bottom and the sides.
- the actuating means are arranged to receive, as pressurized fluid, a fluid of the drilling or coring fluid type.
- the actuation means are arranged to receive, as pressurized fluid, an expansion fluid pressurized by a fluid of the drilling or coring fluid type via 'a separation piston.
- Said stopper 53 can comprise (FIG. 11), in a bar 73 which composes it, a lock 75 which is pushed into abutment by a spring 77 in a projecting position outside the bar 73 and which can be pushed back into a retracted position in said bar 73 by an external action.
- the latch 75 has at each of its front and rear ends an inclined face arranged so that, when the plug 53 is inserted into the outer tube 33 or removed therefrom, said latch 75 automatically retracts into the bar 73.
- the annular piston 89 is held in said starting position by a breakable element 91, such as a pin, calibrated to break under a thrust of the piston 89 subjected to a pressure beyond a given threshold.
- a breakable element 91 such as a pin
- a positioning stop 99 ( Figure 5), in particular combined with the ring 69 , which can bear against an adequate surface provided in the outer tube 33.
- a releasable lock 100 in particular to two bolts 101, which is mounted on the pipe 39, including the two bolts 101, shaped accordingly, are automatically blocked by the action of a spring 103 in longitudinal notches 105 or other receptacles cut in the outer tube 33.
- the two bolts 101 are removed from the notches 105 in a known manner.
- in front of the expandable device 9 can be arranged a guide nose 107 whose front end is preferably hemispherical.
- valve 22 In the position illustrated in Figure 17, the valve 22 is in the up position.
- the second part 114 takes, under its own weight, support on a seat 115 of the first part 113 and thus frees an annular passage 116 between the first part 113 and the second part 114 of the valve 22.
- the valve 22 allows the fluid supplied from the cylindrical cavity 112 to pass through to the cylindrical chamber 117 in which the separation piston 20 is arranged.
