Description
Technical field
The utility model relates to a kind of pneumatic self-cleaning mouse hole device.Be the oil drilling aid, particularly make up a joint or during casing job, the utility model can eject the muddy water things such as drilling fluid that retain in the mouse hole with compressed air creeping into, to keep the cleaning in the mouse hole.
Background technology
In petroleum drilling operation, for the length that prolongs drill string to deepen well, need in drilling process, implement to connect the single operation of drilling tool, but when connecing the single operation of drilling tool, drilling fluid in kelly bar and the hose, some can flow in the mouse hole, the lower end of mouse hole is embedded in below ground in addition, so the drilling fluid muddy water thing in the inflow mouse hole can retain wherein, the single external screw thread of drilling tool of putting into mouse hole this moment will be subject to the immersion of the muddy water things such as drilling fluid that mouse hole retains, and can stick on the external threaded surface, and affect the scribble effect of drilling tool thread fat, cause drilling tool thread gluing phenomenon to happen occasionally; Secondly, when casing job, that the sleeve pipe of G.I.H is single also will put into first mouse hole, same its single external screw thread also will be stained with the muddy water things such as drilling fluid, and affect smearing of bobbin seal fat, cause the casing string junction poorly sealed, and then affect follow-up oil producing operation.
Summary of the invention
The purpose of this utility model is a kind of pneumatic self-cleaning mouse hole device with the one-way pneumatic valve assembly of design, make it have enough intensity and reliability, during use, make compressed air enter the mouse hole bottom by controlling jettron, the muddy water things such as drilling fluid that the mouse hole bottom is retained eject beyond the mouse hole, realize the cleaning in the mouse hole, to guarantee the single or single externally threaded cleaning of sleeve pipe of drilling tool.
Use the present technique solution to achieve the above object: pneumatic self-cleaning mouse hole device mainly by pneumatic operated valve pedestal, pneumatic valve core, annular give vent to anger frame, air inlet pipe, blow-off pipe, rat-hole scabbard, pneumatic valve core axis hole, rubber cushion, pneumatic valve core bracing frame, connect lacing wire, by-pass prot, venthole and form.Described pneumatic operated valve pedestal, pneumatic valve core and the annular frame of giving vent to anger is combined into one-way pneumatic valve assembly of the present utility model; The center of described pneumatic operated valve pedestal is provided with the pneumatic valve core axis hole, is provided with the through hole that drilling fluid can flow through around the pneumatic valve core axis hole, and pneumatic operated valve pedestal lower member is to utilize a bit of round steel pipe to be made, and is provided with by-pass prot around the pneumatic operated valve pedestal bottom; Pneumatic valve core be with a circular steel plate as the moving valve core print seat, therein heart position perforate also penetrates one section round steel, and weld together the composition matrix with it, and then laying one center circular rubber cushion with holes is made on circular steel plate; The annular frame of giving vent to anger is to be welded with one section seamless steel pipe, and top is provided with venthole, and the annular frame center of giving vent to anger is provided with the pneumatic valve core bracing frame, and it welds together by being connected lacing wire with the pneumatic operated valve pedestal.
The beneficial effects of the utility model are: because the utility model is to be made with the thick-walled metal material, therefore have enough intensity and reliability; Because the utility model is to utilize air cock to control compressed air to enter the mouse hole bottom, the pressure of pneumatically, the muddy water things such as drilling fluid that retain in the mouse hole are ejected, so, simple to operate and result of use good, quick when removing the muddy water things such as drilling fluid that retain in the mouse hole, easy, thus avoided manpower to remove drawback thorough and that waste time and energy.Secondly movable part of the present utility model all is contained in rat-hole scabbard inside, thereby is difficult for bumping, damaging, and has long application life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the assembling schematic diagram after rat-hole scabbard of the present utility model and the pneumatic valve body complete section.
Fig. 2 is the assembling explosive view of one-way pneumatic valve assembly of the present utility model.
Fig. 3 is that pneumatic operated valve pedestal of the present utility model adopts the pneumatic operated valve general assembly schematic diagram after partly cuing open.
In the accompanying drawing: pneumatic operated valve pedestal (1), pneumatic valve core (2), annular give vent to anger frame (3), air inlet pipe (4), blow-off pipe (5), rat-hole scabbard (6), pneumatic valve core axis hole (7), rubber cushion (8), pneumatic valve core bracing frame (9), connect lacing wire (10), by-pass prot (11), venthole (12).
The specific embodiment
In conjunction with Figure of description, the utility model will be further described:
The utility model by pneumatic operated valve pedestal 1, pneumatic valve core 2, annular give vent to anger frame 3, air inlet pipe 4, blow-off pipe 5, rat-hole scabbard 6, pneumatic valve core axis hole 7, rubber cushion 8, pneumatic valve core bracing frame 9, connect lacing wire 10, by-pass prot 11 and venthole 12 and form.Make first the upper member of pneumatic operated valve pedestal 1 with thick steel sheet, lower member and the upper member that will hold the pneumatic operated valve pedestal 1 of by-pass prot 11 successfully weld together again; After welding is good, other gets the circular steel plate of a center drilling, heart position of opening penetrates round steel and welds together therein, the matrix that forms pneumatic valve core 2, and then on circular steel plate laying one center circular rubber cushion with holes, make pneumatic valve core 2, after making, in its pneumatic operated valve pedestal 1 of packing into, the frame 3 of again annular being given vent to anger is welded on the lower end of pneumatic operated valve pedestal 1 by connecting lacing wire 10, during use, pneumatic valve core 2 can be done with the constraint of pneumatic valve core bracing frame 9 by pneumatic valve core axis hole 7 and is slided up and down in pneumatic operated valve pedestal 1.
