Means are then arranged between the front and rear sections of the outer tube so that one can be rotated about its longitudinal axis independently of the other.
- the motor stator may be fixed in rotation relative to the rear section of the outer tube, during coring, while the motor rotor is then fixed in rotation to the front section of outer tube.
- the drill string and the rear section of the outer tube are significantly less subject to wear and fatigue due to stresses of the type by alternating bending of the tubes rotating in curves of the well.
- the regularity of the rotation of the crown thus driven by the motor is greater than that which the drill string would provide since there is no interference from friction of the rods against the wall of the well.

- these throttling means 34 are formed for example by an annular boss 35 on the inner tube assembly 8 and by an internal annular flange 36 corresponding to the outer tube 3.
- These throttling means 34 are provided to indicate for example an abnormal situation during coring, as described below.
- the motor 17 is advantageously of a type actuated by the coring fluid.
- the motor 17 can be arranged in the system of conduits 39 (FIGS. 2 and 6) for the passage of fluid so that it participates in the aforementioned hydrodynamic means, at least for the part of said fluid which actuates it. .

- shut-off valve 54 arranged to open in the event of fluid overpressure at inlet 42 of motor 17, this shut-off valve 54 preferably being a calibrated disc 54 which pierces at a determined overpressure.
- the core barrel 1 of the invention may further comprise ( Figures 1 and 3) a seal system 55 mounted on the inner tube assembly 8 so that in the active position, it substantially completely closes the annular space 56 between the outer tube 3 and this assembly 8 and it thus receives, in the manner of a piston, the full pressure of the coring fluid.
- the seal system 55 may comprise at least two flat circular seals 57 and 58, the external edge 57a, 58a (FIG.
- the inner tube assembly 8 can advantageously include a sleeve 62 disposed downstream of the seal system 55 so as to have no action on the latter during the descent of the inner tube assembly 8 in the outer tube 3 and in during core drilling, but so as to slide beforehand upstream on the inner tube assembly 8 during a withdrawal of the latter from the outer tube 3.
- the sleeve 62 engages with the system seal 55 and then moved away from the outer tube 3, in a folded position 55R against the inner tube assembly 8, so that the fluid can again flow through the annular space 56, having an effect more reduced or even practically zero on the joint system 55 and therefore on said assembly 8.
- the core barrel 1 of the invention with a probe 63 disposed in the inner tube proper 9.
- a section 64 of this probe 63 equipped with measurement means not shown or described in detail because they are known from those skilled in the art then protrude from this inner tube 9 during the descent of the inner tube assembly 8 into the outer tube 3 and in the core position of the inner tube proper 9 relative to the outer tube 3 then that the latter is still away from a bottom of a well.
- the probe 63 is also arranged in the inner tube 9 so as to be able to be pushed back inside of it, during coring, by the bottom of the well and or by the top of the core.
- This type of probe 63 may include means for recording the measurements made, so that they can be examined on the surface when the assembly 8 has been removed from the well and that the probe 63 has been put in connection with suitable apparatus. .
- the front section 3A of the outer tube 3 is introduced into the rear section 3P, from the rear, before connecting to each other at 66 (FIG. 6) sections of the outer tube 3. It is arranged so as to be able to slide there between a position of suspension in the rear section 3P, by the reciprocal effect of the stops 13A, 13P ( Figure 7), and an extreme pressed position, in the rear section 3P, limited by the reciprocal effect of the stops 12A , 12P (figure 6 or 7).
- the crown 5 can then be mounted on the front section 3A.
- the outer tube 3 thus equipped can be fixed to the drill string 2 ( Figure 1 or 3) and be lowered into a well to be cored.
- the inner tube assembly 8 can be lowered into the outer tube 3, according to the known technique known as the wire-line, the case if necessary using a hooking device 67 ( Figure 1 or 3) known that the assembly 8 comprises. Coring fluid sent at this time under pressure into the outer tube 3 can bear on the seal system 55 in order to assist in the descent of the inner tube assembly 8, especially if the outer tube 3 does not only follow a vertical but takes a steep inclination with respect to it, even to the horizontal.
- the inner tube assembly 8 can thus descend until it abuts (FIG. 2) against the abovementioned stop 49.
- said assembly 8 is at the same time in abutment, during coring, against the abutment abutment 14 (FIG. 6) by which it can act on the front section 3A.
- the hooking device 67 is forced to push in a direction S a connecting bar 68 (FIG. 1 or 3) into said assembly 8, by causing a locking pin 69 to break, until 'a face 70P of a recess 70 of the bar 68 comes to bear against a stop pin 71.
- channels 72 and 73 isolated from each other until there by seals 74, are placed in communication and coring fluid can flow from this moment from inside the drill string 2, through the annular space 75 and the channels 72, 73 in a conduit 76 ( Figure 1 or 3, and Figure 2) dug in the connecting bar 68, in conduits 77, to the crown 5.
- the fluid undergoes from at least the upper end of the tube assembly inside 8 until it leaves the crown 5 a usable pressure drop.
- the front section 3A is rotated by the rear section 3P by means, not shown but known to those skilled in the art, which allow the aforementioned sliding.
- the crown 5 can, if necessary, partially push back in the rear section 3P the front section 3A, until the latter is in abutment against the bearing stop 14 of the inner tube assembly 8.
- the assembly 8 subjected to the pressure of the fluid, offers the front section 3A a resistance determined by this pressure which depends inter alia on the pressure drop produced by the nozzle 10.
- said anterior section is rotated by the rear section 3P by means, not shown but known to those skilled in the art, which allow the aforementioned sliding.
- the crown 5 can, if necessary, partially push back in the rear section 3P the front section 3A, until the latter is in abutment against the bearing stop 14 of the inner tube assembly 8.
- the assembly 8 subjected to the pressure of the fluid,
- the drill string 2 is at least partially in tension and therefore held straighter, even horizontally, than is usually possible when it is completely in compression and therefore subject to a buckling.
- the crown 5 receives under these conditions a much more regular weight than with a train of rods in a situation of buckling and subjected to significant friction against the wall of the well.
- the crown 5 can therefore progress with more regularity in training 4. All of this promotes, among other things, the ability to correctly direct the crown 5.
- the anterior section 3A can be maintained in the posterior section 3P, by the pressure on the assembly 8, in positions in which the reciprocal stops 12A, 12P on the one hand and 13A, 13P on the other hand are not in respective contact. If in addition the assembly 8 is not abutted against the valve 45 but the latter is held against its seat 48 by a fluid pressure upstream higher than that downstream, we obtain what can be called a decoupled operating mode.
- the anterior 3A and posterior 3P sections of the outer tube 3 can then slide relative to each other under the effect of the pressure on the assembly 8.
- the front section 3A can progress on its side in a regular manner, solely as a function of the action of the crown 5 in formation 4 during coring.
- the assembly 8, the front section 3A and the crown 5 can thus move longitudinally in one direction or the other, relative to the rest of the drill string 2, depending on whether the speed of the drill string 2 is lower or higher. to that of the crown 5 in formation 4, and this can be adjusted from the surface by acting on the drill string 2.
- the anterior stop 46 which the assembly 8 carries comes into contact with the valve 45 and can push the latter away from the valve seat 48. From this fact, the fluid which until then could only pass through the conduit 50 (FIG. 2) and the nozzle 10 can now also pass between the valve 45 and its seat 48, and this considerably reduces the pressure drop in the core barrel 1, therefore the pressure applied to the assembly 8 and consequently the force exerted by the crown 5 on the formation 4.
- the core barrel 1 of the invention is thus put out of service practically automatically in the event of an exaggerated effort to be provided, and that for the benefit of its constituents, by direct action at the place of these at the bottom of the well.
- the drill string 2 should not rotate the crown 5, it can be rotated at reduced speed in order to, for example, prevent the train 2 from sticking to the wall of the well. If, for any reason known to those skilled in the art, the crown 5 and / or the front section 3A oppose an excessive resistive torque to the motor 17, this increases the pressure upstream of the latter. The tared disc 54 can then be pierced when the pressure reaches a safety limit value there for the motor 17, and the fluid is diverted from the inlet 42 of the engine 17 towards the duct 51 and the outlet at the location of the crown. 5, and the motor 17 stops.
- the throttling means 34 (FIG. 3) can come into action and, by throttling the passage of the fluid, cause a significant increase in pressure upstream of these means 34.
- This increase in pressure causes the warning explained above and the operator can again adjust the fluid flow and / or the advance of the drill string accordingly 2.
- three different protections of the motor 17 and of the crown 5 can be provided simultaneously or separately or even according to any combination of two of them.
