The rubber core guider for the under-balanced drilling is reasonable and compact in structure and easy to use, can reduce the difficulty of rubber core insertion to achieve simple operation and facilitate rubber core replacement, and meanwhile, reduces the security threats to operation personnel, saves the working hours of rubber core replacement and improves the working efficiency.
Description
Technical field
the utility model relates under balance pressure drilling with changing glue core apparatus technical field, is glue core target seeker for a kind of under balance pressure drilling.
Background technology
in the process of under balance pressure drilling, it needs often to change the glue core of swivel control head assembly, at present, in the process of changing the glue core, at first operating personnel wear in glue core frame by the swivel control head assembly being sling and being placed on, the thrust of utilizing the drilling rod deadweight to produce, worn the operation of glue core by the mode of transferring drilling rod, because new glue in-core footpath is less, and the screw thread of drilling rod lower contact place has roughness, while making drilling rod be passed down through the glue core, resistance is larger, make in wearing glue core process, the glue core is due to painstaking large and can't complete and wear the operation of glue core and thereby the drilling rod distortion easily causes casualty accident, brought very large threat to operating personnel's personal safety, not only increased the difficulty of operation, and increased the risk of well head safe operation.
Summary of the invention
the utility model provides glue core target seeker for a kind of under balance pressure drilling, overcome the deficiency of above-mentioned prior art, its can effectively solve existing swivel control head assembly reality change the difficulty of wearing the operation of glue core existed in the process of glue core high, operating personnel's personal safety is threatened and there is the problem of risk in shaft mouth operation.
the technical solution of the utility model realizes by following measures: glue core target seeker for a kind of under balance pressure drilling, comprise top guide body, transition block and stationary cylinder, the lower end of top guide body and the upper end of transition block are fixed together, the lower end of transition block and the upper end of stationary cylinder are fixed together, the top guide body is spherical, and transition block is taper wide at the top and narrow at the bottom.
below the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned top guide body, transition block and stationary cylinder can be integrated.
can there be conical cavity the above-mentioned lower end in transition block, and the bottom surface diameter of conical cavity is identical with the internal diameter of stationary cylinder.
can there be the internal thread button the above-mentioned inboard at stationary cylinder.
above-mentioned top guide body can be nylon resin top guide body, and transition block is the nylon resin transition block, and stationary cylinder is the nylon resin stationary cylinder.
the utility model reasonable and compact in structure, easy to use, it is in the process of changing the glue core, can reduce the difficulty of wearing the operation of glue core, simple to operate, thus be convenient to change the glue core, reduced the threat to operating personnel's personal safety simultaneously, save the activity duration of changing the glue core, improved operating efficiency.
The accompanying drawing explanation
accompanying drawing 1 is looked the sectional structure schematic diagram for the master of the utility model most preferred embodiment.
accompanying drawing 2 is the utility model most preferred embodiment looks up structural representation.
coding in accompanying drawing is respectively: 1 is the top guide body, and 2 is transition block, and 3 is stationary cylinder, and 4 is the internal thread button, and 5 is conical cavity.
The specific embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all to be described according to the Butut mode of Figure of description 1, as: the position relationship of forward and backward, upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in accompanying drawing 1,2, this under balance pressure drilling comprises top guide body 1, transition block 2 and stationary cylinder 3 with glue core target seeker, the upper end of the lower end of top guide body 1 and transition block 2 is fixed together, the upper end of the lower end of transition block 2 and stationary cylinder 3 is fixed together, top guide body 1 is spherical, and transition block 2 is taper wide at the top and narrow at the bottom.The setting of spherical top guide body 1 can improve the success rate of punching.
can according to actual needs, above-mentioned under balance pressure drilling be made further optimization and/or improvements with glue core target seeker:
as shown in accompanying drawing 1,2, top guide body 1, transition block 2 and stationary cylinder 3 are integrated.The setting that top guide body 1, transition block 2 and stationary cylinder 3 are integrated can make top guide body 1, transition block 2 and stationary cylinder 3 more firm in the process of using.
as shown in accompanying drawing 1,2, in the lower end of transition block 2, conical cavity 5 is arranged, the bottom surface diameter of conical cavity 5 is identical with the internal diameter of stationary cylinder 3.
