The pressurized petroleum wellhead driller comprises a body, a hydraulic motor, a drill stem, a feed screw nut, a cross beam, a handle, a drilling tool, two hydraulic oil cylinders, a sealing flange and an atmospheric valve, wherein the hydraulic motor is assembled on the top of the body; the drill stem the upper end of which extends into the body is driven by the hydraulic motor; the body is screwed in the feed screw nut; the cross beam is fixed on the feed screw nut; the handle is positioned on the top of the cross beam and fixed on the feed screw nut; the drilling tool is assembled on the lower end of the drill stem; the two hydraulic oil cylinders are positioned on both sides of the drill stem and symmetrically assembled on the cross beam; the drill stem is nested in the sealing flange which is arranged on the body; an air channel is arranged between the flange and the drill stem; one end of the atmospheric valve extends into the sealing flange; and the atmospheric valve is communicated with the air channel. The utility model can safely carry out a drilling operation at high speed.
Description
Technical field:
The utility model is the valve plate boring that is used for oil, natural gas well muzzle pipe and well head dress main control valve, presses drilling equipment in particular for the oil well head band of reelecting that can only Operating Pressure equipment.
Background technology:
At present, in the operation of petroleum and natural gas well muzzle pipe and the rectification of wellhead assembly main control valve, the main control valve corrosion is serious, can't open pressure release, can not realize that kill-job circulation carries out kill job, cause well head can't produce maybe and can't carry out workover treatment, bring enormous economic loss to production.
The utility model content:
The purpose of this utility model is to press drilling equipment for the high oil well head band of safety, efficient that a kind of main control valve perforate that can't open in oil, natural gas well muzzle pipe and rectification of wellhead assembly main control valve and workover treatment is provided.
The purpose of this utility model is achieved like this:
The utility model oil well head band is pressed drilling equipment, comprise fuselage, be loaded on the hydraulic motor at fuselage top, the drilling rod that driven by hydraulic motor is stretched in the upper end, the feed screw nut who is threaded with fuselage, be fixed on the crossbeam on the feed screw nut, be positioned at the crossbeam top and be fixed on handle on the feed screw nut, be loaded on the drilling tool of drilling rod lower end, be positioned at drilling rod both sides symmetry and be loaded on two hydraulic jacks on the crossbeam, have on the fuselage be enclosed within on the drilling rod and and drilling rod between the sealing flange of air duct is arranged, atmospheric valve one end stretches in the sealing flange and with air duct and communicates.
On the above-mentioned sealing flange inwall high-pressure sealing ring is housed.
Above-mentioned crossbeam is contained in the feed screw nut and goes up and be fixed on the feed screw nut by locking nut.
When using the utility model, at first at the external by-pass valve control of drilled main control valve, outside by-pass valve control, install the utility model band and press drilling equipment by technical requirements, choose drilling tool according to technical requirements, be contained in band and press on the drilling rod of drilling equipment, will be installed in by the sealing flange of technical requirements apolegamy between gate valve and the band pressure drilling equipment.Open the control gate valve, can carry out bore operation the well head main control valve.Before the bore operation, check the sealing between gate valve and drilling equipment, after sky has bored (being pressed with pressure on the pressure meter shows), the hydraulic motor counter-rotating, cutter is return original position, shuts gate valve, high-pressure medium between around gate valve and the cutter is discharged by atmospheric valve, unload band and press drilling equipment.
Can select by Technology Need because of sealing flange and drilling tool in the utility model, can adapt to the needs of certain limit size perforate, the hole that this band presses drilling equipment can bore 20mm～60mm; Press drilling equipment to design prior mounted gate valve and be connected with reelecting on the utility model band by sealing flange by technology, after drilling main control valve, can use this passage to carry out ordinary production, also can carry out a step workover treatment, simultaneously, utilize band to press and change valve technology replacing brill main control valve.Compare with the well killing change main control valve, greatly reduce cost, have high economic benefit; Because of the perforate operation is to finish in hermetically sealed, the leakage of media such as gas, liquid can not take place, when reelecting, technology need not to adopt the auxiliary security measure, and safe and reliable during operation.
The utility model device is holed to valve plate under well head situation with pressure, carries out bore operation safely, at high speed.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that hydraulic motor, hydraulic jack, fuselage position concern schematic diagram.
Fig. 3 is that atmospheric valve, sealing flange and No. 4 valve positions concern schematic diagram.
The specific embodiment:
Referring to Fig. 1～Fig. 3, the utility model oil well head band is pressed drilling equipment, comprise fuselage 1, be loaded on fuselage top hydraulic gerotor motor 2, the drilling rod 3 that driven by the hydraulic gerotor motor is stretched in the upper end, the feed screw nut 4 who is threaded with fuselage, be contained in that the feed screw nut goes up and be fixed on crossbeam 6 on the feed screw nut by locking nut 5, be positioned at the crossbeam top and be fixed on handle set 7 on the feed screw nut, be loaded on the handle 8 on the handle set, be loaded on the drilling tool 9 of drilling rod lower end, be positioned at drilling rod both sides symmetry and be loaded on two hydraulic jacks 10 on the crossbeam.Have on the fuselage be enclosed within on the drilling rod and and drilling rod between the sealing flange 12 of air duct 11 is arranged, atmospheric valve 14 1 ends of band pressure meter 13 stretch in the sealing flange and communicate with air duct.High-pressure sealing ring 15 is housed on the Sealing Method inwall.
Referring to Fig. 1, when using the utility model, close No. 4 valves 16 of oil recovery (gas) tree, bleed off the above residual air of valve No. 4, with bolt 17 the utility model device is fixed on No. 4 valves, No. 4 valves of standard-sized sheet drive hydraulic jacks and move downward and drive this device and move downward on drilling rod drill bit near No. 1 valve 19 valve plates 20 thereby start Hydraulic Station 18, thereby start Hydraulic Station 18 and start gerotor motor, drive the drilling rod rotation; Clockwise rotate handle slowly even bring into to, by screw thread pair drilling rod is moved downward, bore gradually to No. 1 valve valve plate, realize boring, until drilling valve plate to No. 1 valve valve plate.Be rotated counterclockwise turning handle, drilling rod and drill bit are withdrawed from more than No. 1 valve valve plate, stop the hydraulic pressure gerotor motor, starting Hydraulic Station drive liquid oil cylinder moves upward, more than withdrawing from No. 4 valve valve plates to drilling rod and drill bit, close No. 4 valves, No. 4 above residual air of valve of emptying, remove the utility model drilling equipment.
