In other embodiments of the invention, a circulating tool may be provided which will remain open even when the flow rate or pressure of the circulating pressure is reduced. In the interest of brevity, and for ease of understanding, such a tool will be described with reference to the tool 10 as described above, and in addition with reference to FIG. 3 of the drawings, which illustrates a section of a continuous “J”-slot arrangement forming part of such a tool. The slot 120 is provided in a sleeve which is rotatable relative to the tool body 12, but fixed axially relative to the body, while the pin 130 extends radially from the second sleeve part 20, FIG. 3 illustrating seven different pin positions 130 a–130 f.
The first pin position 130 a corresponds to the tool configuration as shown in FIG. 1 (it should be noted that the slot 120 is shown inverted in FIG. 3). When the pumps are cycled for the first time the secondary pressure chamber piston 76 moves the first and second sleeve parts 18, 20 downwards by a first increment, and pushes the pin from 130 a to 130 b. If the pumps are cycled (that is, turned off and on) another three times in quick succession, the pin will move through positions 130 c and 130 d to position 130 e; any further cycling of the pumps will not move the pin 130 further, as the piston 76 will have reached the end of its stroke.
If the pumps are not cycled again, the bleed valve 77 allows the piston 76 and the first sleeve part 18 to move back towards the first position, however the pin 130 is retained in position 130 f, such that the second sleeve part 20 remains in the second position. The tool is thus stable in this configuration, and the ports 28, 98 remain aligned.
In order to close the ports 28, and move the pin from position 130 f, it is necessary to cycle the pumps four times in order for the first sleeve part 18 to be moved from its first position to contact the second sleeve part 20 and push the pin 130 to position 130 g, from where the pin 130 is free to move and allow the sleeve part 20 to move upwards relative to the body. Thus, if the pumps are not cycled again, the bleed valve 77 allows the piston 76, and with it the sleeve parts 18, 20, to return to the first position, with the pin moving back to position 130 a.
