摘要： A well tool device includes a housing having an axial through bore. The well tool device further includes a sleeve section axially displaceable relative to the housing; a fluid flow preventing frangible disc; and an axial fluid passage bypassing the frangible disc when the well tool device is in an initial state, thereby allowing a fluid flow between a first location above the frangible disc and a second location below the frangible disc. The sleeve section includes an axial through bore aligned with the axial through bore of the housing. The axial fluid passage is closed when the well tool device is in a subsequent state. The fluid flow preventing frangible disc is provided in the bore of the sleeve section in sealing engagement with the sleeve section. The well tool device further includes a disc supporting device for supporting the frangible disc in relation to the sleeve section. The disc supporting device is releasably connected inside the sleeve section by means of a releasable connection device. The well tool device further includes a disintegration device disintegration of the frangible disc, wherein the well tool device is in a final state when the frangible disc has been disintegrated by the disintegration device.

摘要： A well tool device includes a housing having an axial through bore; a sleeve section releasably connected to the housing in the axial through bore, wherein the sleeve section comprises an axial bore; a frangible disc provided in the axial bore of the sleeve section in sealing engagement with the sleeve section. The sleeve section is axially displaceable within the axial through bore between a first position and a second position. The well tool device includes a first supporting sleeve fixed to the housing in the axial through bore and a second supporting sleeve provided radially inside of, and releasably connected to, the first supporting sleeve. The first supporting sleeve includes an upwardly facing surface configured to support a lower end of the sleeve section when the sleeve section is in the second position.

The sleeve section includes an axial through bore aligned with the axial through bore of the housing. The axial fluid passage is closed when the well tool device is in a intermediate state. The fluid flow preventing frangible disc is provided in the bore of the sleeve section in sealing engagement with the sleeve section. The well tool device further includes a disc supporting device for supporting the frangible disc in relation to the sleeve section. The disc supporting device is releasably connected inside the sleeve section by a releasable connection device. The well tool device further includes a disintegration device disintegration of the frangible disc. The well tool device is in a final state when the frangible disc has been disintegrated by the disintegration device. The frangible disc is configured to be pushed axially relative to the sleeve section towards the disintegration device after release of the disc supporting device.

摘要： The present invention relates to a well tool device (1) comprising a housing (10) having an axial through bore (11). A sleeve section (20) is releasably connected to the housing (10) in the through bore (11). The sleeve section (20) comprises an axial bore (21) and a frangible disc (30) provided in the bore (21) of the sleeve section (20) in sealing engagement with the sleeve section (20). The sleeve section (20) is axially displaceable within the bore (11) between a first position (P1) and a second position (P2). The housing (10) comprises an axial bypass fluid passage (12) provided axially between a first location (L1) above the sleeve section (20) to a second location (L2) below the sleeve section (20) when the sleeve section (20) is in the first position (P1). The axial bypass fluid passage (12) is provided radially between the sleeve section (20) and the housing (10) when the sleeve section (20) is in the first position (P1). The well tool device (1) comprises a sealing device (36) provided radially between the sleeve section (20) and the housing (10) when the sleeve section (20) is in the second position (P2).
