摘要： A downhole tool apparatus such as a packer or bridge plug, for use in a well bore, comprises a centre mandrel (102), a slip wedge (126) around the mandrel, separate non-metallic slips (116) around the mandrel adjacent the wedge, and means (117) for retaining the slips initially out of engagement with the well bore. The non-metallic material may include engineering grade plastics. The slips can be separate and held in place in an initial position around the slip wedge by a retainer ring, or they may be integrally formed with a fracturable ring portion which holds the slips in the initial position around the wedge.
The use of non-metallic material improves the drillability of the apparatus when drilling is required to remove the apparatus from the well.

摘要： A downhole well bore packing apparatus (eg. a packer or bridge plug) includes a component which bears compressive loading and is made of plastics material. Such components can be lock ring housings (24), slips (28,54), slip wedges (32,46) or slip supports (24,58) for example. After use of the packing apparatus downhole, it can be relatively easily drilled out.

摘要： A downhole apparatus (102) for use in a wellbore comprises: a mandrel (14) having an axial centerline; a slip means (118) disposed on the mandrel for grippingly engaging the wellbore when set into position; at least one packer element (128) to be axially retained about the mandrel and located at a preselected position along the mandrel defining a packer element assembly; at least one packer element retainer shoe (150) made of a plurality of segments for axially retaining the or each packer element about the mandrel, the shoe segments further having a cavity (168) for accommodating at least a portion of at least one gap-spanning structural member (170) that is installable into the cavity; and means (152) for retaining the shoe segments in an initial position about the mandrel. The gap-spanning member is of such size and configuration to span a gap that forms between adjacent shoe segments upon the tool being set in the wellbore.

摘要： A downhole tool apparatus such as a packer or bridge plug utilises non-metallic components, eg. engineering grade plastics components. The non-metallic components may include a center mandrel (22), slips (28,54), slip wedges (32,46), slip supports (24,58) and housings, spacer rings, valve housings and valve components. These tools can be relatively easily drilled out after use without significant variations in the drilling speed and weight applied to the drill bit may be employed. Alternative drill bit types, such as polycrystalline diamond compact (PDC) bits may also be used.
