摘要:
A dissolvable tool includes a body having at least a portion configured to dissolve in a fluid, and a barrier connected to the body. The barrier is configured to slidably fluidically seal to a structure that the body and the barrier are movable within to maintain a volume of the fluid between the barrier and the body while the barrier and the body are moved through the structure.

A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or multi-acting circulation valve allows switching between the squeeze and circulation positions without risk of closing the low bottom hole pressure ball valve. The low bottom hole pressure ball valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the low bottom hole pressure ball valve. The multi-acting circulation valve can prevent fluid loss to the formation when being set down with the crossover tool supported or on the reciprocating set down device and the multi-acting circulation valve is closed without risk of closing the wash pipe valve.

A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve. The wash pipe valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the wash pipe valve. The jet valve can prevent fluid loss to the formation when being set down whether the crossover tool is supported on the packer or on the smart collet.

A counter assembly including an actuatable component. A counter component is disposed with the actuatable component and initially in a first position relative the actuatable component and movable with respect to the actuatable component. A lock member is engaged in a track formed between the actuatable component and the counter component. The lock member is operatively arranged for enabling relative movement between the actuatable component and the lock member in a first direction only and between the counter component and the lock member in a second direction only. At least one iteration of travel of the counter component to a second position relative the actuatable component and back to the first position progresses the lock member incrementally along the track. The actuatable component is immovably locked to the counter component by the lock member when the lock member has reached an end of the track.

A valve on an inner string can only be closed with multiple movements in opposed directions that occur after a predetermined force is held for a finite time. Holding the force against resistance eventually allows movement that arms the valve. A set down and pickup force will then close the valve. The surrounding string has a constriction that interacts with a j-slot to rotate a wedge with a first peak into alignment with a peak on a second wedge that can only translate against a spring bias. The second wedge is eccentrically linked to a ball that rotates between and open and a closed position.
