Description
Technical field
The utility model belongs to the oil development well repairing device, during especially for well pulling job the oil pipe inner fluid of mentioning and dismantle screw thread is carried out well workover well head directional stream-guidance device.
Background technology
Oil pipe is the oil flow channel that connects down-hole deep well pump and ground, generally is to be full of fluid in the oil pipe, has opened the down-hole bleeder when well workover, and the fluid in the oil pipe just flows into pit shaft by the down-hole bleeder.But when bleeder is unkitted in the down-hole, or reasons such as roofbolt disconnectedly takes off, plunger is met card take place cause under the situation that the down-hole bleeder can't open, fluid in the oil pipe can not flow in the pit shaft, will be along with the oil pipe that trips out takes ground to, after well head was dismantled the oil pipe screw thread, the fluid in the oil pipe will be ejected into ground, cause the wasting of resources, environment pollution influences job scheduling, even leads to security incident.
Summary of the invention
The purpose of this utility model is to provide a kind of well workover well head directional stream-guidance device, it can adapt to since the oil pipe inner fluid that causes of a variety of causes can not earial drainage the trip-out operation, particularly to contain corrosive liquids in the oil pipe inner fluid, toxic and harmful has the excellent prevention effect, therefore it is not only a kind of safety and environmental protection protection tool, and be a kind of energy-conservation instrument that prevents the wasting of resources, it has improved operating efficiency, has guaranteed production safety.
The technical solution of the utility model is, design a kind of well workover well head directional stream-guidance device, it is characterized in that: the long cover of two same structure semicircles 6 is fixed on the axillare 2 by screw, suspension ring 1 are fixed on axillare 2 tops, lower seal 8 and last seal 3 are embedded in respectively in the last lower inner cavity of the long cover 6 of semicircle, handle 4 symmetries are fixed on the long cover of two semicircles 6 external surfaces, and retaining mechanism 5 is connected on the external surface of the long cover 6 of two semicircles, and water conservancy diversion pipe nipple adapter sleeve 7 is communicated with the perforate sealing of the long cover 6 of semicircle.
Described retaining mechanism 5 is connected and composed by tapered end and handle 4.
Advantage of the present utility model is:
1, this instrument can be used as oil well and uses being unkitted trip-out operation draining instrument that down-hole bleeder or down-hole bleeder can't open under the situation.
2, this instrument can use separately, also can be used with other blowout prevention instrument.
3, directed fluid discharged can reclaim, and also can be discharged into pollution discharge pond as required or flow back to pit shaft.
4, this instrument installation is simple, easy to operate, and the time spent can not tied up and be hung on the derrick, does not influence the well head operation.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the example structure schematic diagram.
Among the figure: 1, suspension ring; 2, axillare; 3, go up seal; 4, handle; 5, retaining mechanism; 6, the long cover of semicircle; 7, water conservancy diversion pipe nipple adapter sleeve; 8, lower seal.
The specific embodiment
Embodiment as shown in Figure 1, this well workover well head directional stream-guidance device, mainly by about the long cover 6 of two semicircles, water conservancy diversion pipe nipple adapter sleeve 7, " W " type weather strip, go up seal 3, lower seal 8, axillare 2, handle 4, retaining mechanism 5 and suspension ring 1 etc. and form.Two the long cover of semicircle 6 structures are identical about it, and logical screw is fixed on the axillare 2, suspension ring 1 are welded in axillare 2 tops, lower seal 8 and last seal 3 are embedded in respectively in the last lower inner cavity of the long cover 6 of semicircle, being welded on the long cover of two semicircles 6 external surfaces of handle 4 symmetries, retaining mechanism 5 is connected on the external surface of the long cover 6 of two semicircles, makes the long cover 6 of two semicircles can seal locking, and water conservancy diversion pipe nipple adapter sleeve 7 is welded in the perforate of the long cover 6 of semicircle.Retaining mechanism 5 is connected and composed by tapered end and handle 4.About be inlaid with " W " type weather strip between the long cover 6 contact end faces of two semicircles, the sealing performancies when having guaranteed to close locking between two long covers 6 of semicircle.
Its operating principle is: because two long covers 6 of semicircle are separately fixed on two axis holes of same axillare 2 about this device, can be along with axillare 2 turns an angle, stud with " W " type weather strip on the long cover of two semicircles 6 end faces of engagement, seal the mating face of the long cover 6 of two semicircles.After dismantling the oil pipe screw thread, rapidly with this device card on tubing coupling of dismantling and body, and fasten retaining mechanism, at this moment, the following anchor ring of earial drainage device has been stuck in the tubing coupling, and last anchor ring is stuck on the oil pipe body, and the weather strip of last seal 3, lower seal 8 and end face all seals, carry oil pipe slowly and make screw thread break away from box cupling 100-150mm, in the liquid directed discharging of just rapid mozzle flexible pipe in instrument or inflow pit shaft that oil pipe is interior.After liquid stream is clean, take off instrument, can normally play next root oil pipe.
During The field, the plastic flexible pipe that can choose corresponding size and length as required is connected with water conservancy diversion pipe nipple adapter sleeve 7.
Important technological parameters: maximum outside diameter φ 100mm; Length overall 400mm; Weight: 15kg; The oil pipe standard that is suitable for: 2
7/
8TBG; It is φ 73mm that upper tool part clamps diameter, and it is φ 89mm that the bottom clamps diameter, and clamping length is 300mm.
Select φ 6-8mm seizing wire 10-12 rice during use earlier for use, the seizing wire two ends are separately fixed on the suspension ring of derrick two-layer platform place and well head earial drainage device, tool location are adjusted to exceed plane 20-30mm on the well head elevator, fix rope.During trip-out, earlier well head oil pipe screw thread is all unloaded pine (can not on carry oil pipe), again instrument is stuck in the tubing coupling and body of unloading pine, and fasten retaining mechanism, and the following anchor ring of earial drainage device has been stuck in the tubing coupling, and last anchor ring is stuck on the oil pipe body, at this moment, the weather strip of upper-lower seal part and end face all seals, carry oil pipe on slowly to make screw thread break away from box cupling 100-150mm, the liquid in the oil pipe just rapidly the mozzle in the instrument enter flexible pipe and realize directed discharging or flow in the pit shaft.After liquid stream is clean, take off instrument, can normally play next root oil pipe.
