    摘要: A downhole device used to divert fluid flow out of a work string into an annulus. The downhole device is activated by the movement of a plurality of pistons within the downhole device. Fluid flow through a restriction of the downhole device creates an increase in fluid pressure causing the movement of the pistons. The pistons move a flow tube between various locations within the device. In one location, the flow tube prevents fluid flow to the annulus while in another location the flow tube allows fluid flow to be diverted into the annulus. The downhole device may include a locating sleeve having a continuous j-track allowing the flow tube to be selectively retained at the various locations within the downhole device. Fluid flow through the downhole is used to cycle the device between diverting fluid flow to the annulus and forcing fluid flow down the work string.

    摘要: A downhole device used to divert fluid flow out of a work string. The downhole device may be located at any point along a work string at which it may be necessary to divert the fluid flow to the annulus. The downhole device may be activated and deactivated by inserting a single deformable dart into the work string. The device catches the dart blocking fluid flow through the work string. Increased fluid pressure activates the device, which diverts the fluid flow out of the work string into the annulus. A locating sleeve with a continuous j-track allows the device to be retained in activated position. The dart is adapted to deform under a predetermined amount of fluid pressure allowing the dart past the device and returning fluid flow through the work string. The downhole device may be activated multiple times without removing the downhole device from the wellbore.

    摘要: A downhole magnetic debris tool is disclosed that may be connected to the bottom of a packer isolation plug. The downhole magnetic debris tool may include a magnetic shield assembly that shields the magnets and prevent the collection of magnetic debris as the packer isolation plug assembly is run into the well. The packer isolation plug assembly is inserted into the internal seal bore of a set packer. The assembly protects the seal bore from damage and prevents debris from moving downhole. The magnets of the downhole magnetic debris tool may be unsheathed upon removal of the packer isolation plug from the packer. The downhole magnetic debris tool may be used to collect magnetic debris that has collected on top of the packer. Additionally, the magnet shield assembly may act as a debris basket collecting downhole debris while the assembly is pulled from the hole.
