Description
Technical field
The utility model is the kit on oil pumping in oil fields tubing string, glutinous with hollow stem drop mixed with hot water when being heavy crude producing
Corollary apparatus, specifically a kind of glutinous anti-backflow device of heavy oil wells hollow rod water-doped drop.
Background technology
In oil field pumping well production, there are some heavy oil wells, in order to increase the mobility of viscous crude it is necessary to reducing the glutinous of viscous crude
Degree, at present the technical measures of reduction Viscosity of Heavy Crude Oil be using mixing hot water into hollow rod, hot water through hollow rod to
Under from linked hole outflow, then the annular space through hollow rod and oil pipe flows upwards out, and makes hot water in cyclic process to oil
Heavy oil heating drop in pipe is glutinous.This technology needs to use hollow rod, the length of the hollow rod used at present
Generally 9m, and hollow rod roofbolt is 1000m or so, therefore, hollow-rod string is connected by many hollow rods
Form, due to the junction between hollow stem it sometimes appear that leakage problem, hollow when the water mixing into hollow stem is suspended
The external pressure of sucker rod is higher than internal pressure, makes the viscous crude in oil pipe leak into hollow stem, and travel up to ground to set
It is standby inner, cause ground installation to be blocked by viscous crude, prevent its from mix hot water again, it is necessary to increase remove the work blocked could be after
Continue and hot water is mixed into well.
The content of the invention
The purpose of this utility model is to provide a kind of glutinous anti-backflow device of heavy oil wells hollow rod water-doped drop, it is leaked into sky
Viscous crude in heart sucker rod can not be flowed in ground installation, prevented the above-described problem from occurring, and enable thickened oil watering system for a long time just
Often operation.
What the purpose of this utility model was realized in：Including outer cover, valve ball, valve seat, valve body, valve bonnet, feed tube, valve ball
It is placed in the valve pocket of valve bonnet, communication groove is opened up on valve bonnet, the valve pocket UNICOM of valve bonnet is made the valve pocket of valve bonnet by described communication groove
Liquid stream can flow out, valve seat is arranged in valve bonnet, and the upper external thread of the internal thread of valve bonnet bottom and valve body is connected, valve body
The lower surface of valve seat is pushed down in upper surface, the upper surface of valve seat is pressed in the inner circular bead of valve bonnet, the upper surface of valve seat and valve
The contact surface of the inner circular bead of cover keeps sealing, and the diameter of valve ball is more than the aperture of valve seat, and valve ball falls to be sitting on the valve port of valve seat,
The valve port contact position of valve ball and valve seat keeps sealing, liquid stream is flowed to top from the bottom of valve ball, it is impossible to from the top of valve ball
Bottom is flowed to, the top of valve body is provided with centre bore, and feed tube is installed in the side of valve body, and feed tube is communicated with described centre bore,
The bottom of valve body sets hollow polished rod internal thread, beats lateral orifices on the top circular bead surface of valve body, described lateral orifices with it is described
Hollow polished rod internal thread at the top of communicate, outer cover covers external screw thread under the upper external thread of valve bonnet rear lower and valve body and connected
Connect, the inside of outer cover is communicated with described lateral orifices.
The beneficial effects of the utility model are：Valve ball falls to be sitting on the valve port of valve seat, the valve port contact position of valve ball and valve seat
Sealing is kept, liquid stream is flowed to top from the bottom of valve ball, it is impossible to from the overhead stream of valve ball to bottom, therefore, this practicality is new
Type is arranged on the viscous crude that leaks into hollow rod behind the top of the hollow polished rod of oil well and can not flowed in ground installation, can be with
Prevent ground installation from being blocked by viscous crude, thickened oil watering system can normally be run for a long time, it is ensured that heavy oil wells can be produced normally for a long time, have
There is significant economic benefit.
Brief description of the drawings
Accompanying drawing 1 is the installation diagram of the utility model embodiment.
Embodiment
1 pair of the utility model embodiment is illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model embodiment includes outer cover 1, valve ball 3, valve seat 4, valve body 7, valve bonnet 8, feed tube 10,
Valve ball 3 is placed in the valve pocket of valve bonnet 8, and communication groove 2 is opened up on valve bonnet 8, and described communication groove 2 makes the valve pocket UNICOM of valve bonnet 8
The liquid stream of the valve pocket of valve bonnet 8 can be flowed out, and valve seat 4 is arranged in valve bonnet 8, outside the internal thread of the bottom of valve bonnet 8 and the top of valve body 7
Threaded connection, the upper surface of valve body 7 pushes down the lower surface of valve seat 4, the upper surface of valve seat 4 is pressed on the inner circular bead of valve bonnet 8
On, the contact surface of the upper surface of valve seat 4 and the inner circular bead of valve bonnet 8 keeps sealing, and the diameter of valve ball 3 is more than the aperture of valve seat 4,
Valve ball 3 falls to be sitting on the valve port of valve seat 4, and the valve port contact position of valve ball 3 and valve seat 4 keeps sealing, and enables liquid stream under valve ball 3
