Description
Technical field
the utility model relates to drilling tool relief fittings technical field, is a kind of bypass relief fittings.
Background technology
in drilling process, often because of filter screen damage, mud motor comes unstuck and drilling rod corrosion prevention film such as to come off at the reason, causes bit port to block; Drilling tool after blocking cannot set up circulation of drilling fluid passage, there is larger safety and environmental protection risk.
Summary of the invention
the utility model provides a kind of bypass relief fittings, overcomes the deficiency of above-mentioned prior art, and it effectively can solve bit port blocking, cannot set up circulation of drilling fluid passage, there is the problem of larger safety and environmental protection risk.
the technical solution of the utility model is realized by following measures: a kind of bypass relief fittings, comprises joint body; The coupler bore run through up and down is provided with in joint body; On joint body, radial direction is provided with the bypass side opening communicated with coupler bore, is provided with the packing film pad that bypass side opening inner passage can be blocked at bypass side opening internal fixtion.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned bypass side opening can be shoulder hole wide outside and narrow inside, screw thread is provided with in the wide aperture section of bypass side opening, screw thread jackscrew is installed with by screw thread in the wide aperture section of by-pass prot, packing film pad is pressed abd fixed on by screw thread jackscrew on the step end face of by-pass prot inside, in the middle part of screw thread jackscrew, be provided with through hole.
the groove that is threaded in taper wide at the top and narrow at the bottom can be provided with in the upside of above-mentioned joint body; The be threaded bottom of groove is taper type wide at the top and narrow at the bottom and is connected with coupler bore.
the external screw thread that the lower end of above-mentioned joint body can be provided with in back taper wide at the top and narrow at the bottom connects boss.
the thickness of above-mentioned packing film pad can between 1 millimeter to 3 millimeters.
the utility model reasonable and compact in structure, easy to use; When bit port blocking, packing film pad can be crushed by exerting pressure in well, bypass side opening being communicated with the mode of opening and setting up circulation of drilling fluid passage; Simple to operation, safety and environmental protection.
Accompanying drawing explanation
accompanying drawing 1 is that the master of the utility model most preferred embodiment looks sectional structure schematic diagram.
accompanying drawing 2 is I place's structure for amplifying schematic diagram in accompanying drawing 1.
coding in accompanying drawing is respectively: 1 is joint body, and 2 is coupler bore, and 3 is bypass side opening, and 4 is packing film pad, and 5 is screw thread jackscrew, and 6 is through hole, and 7 for being threaded groove, and 8 is external screw thread connection boss.
Detailed description of the invention
the utility model by the restriction of following embodiment, can not 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 be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines 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 bypass relief fittings comprises joint body 1; The coupler bore 2 run through up and down is provided with in joint body 1; On joint body 1, radial direction is provided with the bypass side opening 3 communicated with coupler bore, is provided with the packing film pad 4 that bypass side opening 3 inner passage can be blocked at bypass side opening 3 internal fixtion.
joint body 1 can be used for the connection of the drilling tools such as drill collar in drilling tool, drilling rod, drilling tool stabilizer and crossover sub and drill string component; During hydrophthalmia blocking right overhead, can exert pressure in drilling tool and crush packing film pad 4, bypass side opening 3 is communicated with and open, re-establish circulation of drilling fluid passage by bypass side opening 3; Simple to operation, safety and environmental protection.
according to actual needs, above-mentioned bypass relief fittings can be made further optimization and/or improvements:
as shown in accompanying drawing 1,2, bypass side opening 3 is shoulder hole wide outside and narrow inside, screw thread is provided with in the wide aperture section of bypass side opening 3, screw thread jackscrew 5 is installed with by screw thread in the wide aperture section of by-pass prot 6, packing film pad 4 is pressed abd fixed on the step end face of by-pass prot 6 inside by screw thread jackscrew 5, in the middle part of screw thread jackscrew 5, be provided with through hole 6.
by the mode that packing film pad 4 is fixed by screw thread jackscrew 5, easy disassembly, is convenient to the replacing of packing film pad 4.
as shown in Figure 1, for convenience of connecting, the groove 7 that is threaded in taper wide at the top and narrow at the bottom in the upside of joint body 1, is provided with; The be threaded bottom of groove 7 is taper type wide at the top and narrow at the bottom and is connected with coupler bore 2.
as shown in Figure 1, for convenience of connecting, the external screw thread that the lower end of joint body 1 is provided with in back taper wide at the top and narrow at the bottom connects boss 8.
as required, the thickness of packing film pad 4 is between 1 millimeter to 3 millimeters.The packing film pad 4 used is excessively thin, easily damaged and set up circulation in advance; Packing film pad 4 is blocked up, should not crush; Therefore, proved by field practice, the packing film pad 4 of thickness between 1 millimeter to 3 millimeters is unsuitable damaged, and can be crushed smoothly under rational pump pressure again and set up circulation, reliability is high.
above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
