Further, the position on the petroleum pipeline positioned at the ball-and-seat front end is provided with pressure measurement sampling group Part.
Example, the pressure measurement sampling assemble includes pressure gauge and sample tap valve, the pressure gauge and sampling It is provided with sampling valve between mouth valve.
Further, the end of the gas transmission line is also associated with metering pipeline.
A kind of level pressure tapping equipment that well mouth of oil well set is calmed the anger of the utility model, set is calmed the anger and is emitted into after being trapped It is transmitted in oil pipeline on oil pipe mouth, while controlling pressure in oil jacket annular space and playing shunting discharge within a convenient pressure value The two aspect effect of excess air and control annular pressure.Specifically, a kind of well mouth of oil well set of the utility model is calmed the anger Level pressure tapping equipment has the following advantages:
1, safety valve is preset and is mixed up according to the set pressure of compressed air of required control using spring micro-open type safety valve Opening pressure of safety valve realizes automatic exhaust;
2, a ball-and-seat is also equipped between safety valve and gas transmission line, it is ensured that gas unidirectional flows out, and oil transportation Back pressure is returned the crude oil of row and be may not flow into safety valve on pipeline, avoids that valve clack of safety valve blocking is caused to lead to safety valve failure;
3, set, which is calmed the anger, is controlled in by safety valve restriction in a certain pressure so that gas pressure is in a conjunction in oil jacket annular space In the range of reason, oil extraction is promoted to be pumped into ground, while controlling in oil jacket annular space pressure within a convenient pressure value, Play the role of two aspect of shunting recycling excess air and control annular pressure.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram for the level pressure tapping equipment that well mouth of oil well set is calmed the anger of the utility model.
In figure, 1. sucker rods, 2. oil pipes, 3. oil pipe mouth valves, 4. four-way junction of casing, 5. sleeve opening valves, 6. casings, 7. take out Oil pump, 8. pressure gauges, 9. sampling valves, 10. sample tap valves, 11. ball-and-seats, 12. safety valves, 13. metering pipelines, 14. oil transportations Pipeline.
Specific implementation mode
The utility model is further described in detail below by drawings and specific embodiments.
A kind of level pressure tapping equipment structure that well mouth of oil well set is calmed the anger of the utility model as shown in Figure 1, including casing 6, It is set to the four-way junction of casing 4 of 6 upper surface of casing and stretches into the oil pipe 2 in casing across four-way junction of casing 4, be provided in oil pipe 2 It works in coordination, the sucker rod 1 for extracting crude oil and oil well pump 7, is extracting the ring between crude oil process middle sleeve 6 and oil pipe 2 Interior aggregation forms set and calms the anger, and 2 top of oil pipe is provided with oil pipe mouth valve 3, and oil pipe 2 is connected with petroleum pipeline by oil pipe mouth valve 3 Line 14, crude oil flow to multi-purpose station by petroleum pipeline 14, and four-way junction of casing 4 is connected with gas transmission line, casing pressure by sleeve opening valve 5 Gas enters after gas transmission line discharge to import in petroleum pipeline 14 by sleeve opening valve 5 flows to multi-purpose station together.Gas transmission line End is also associated with metering pipeline 13.
In order to realize that discharge covers the automation control calmed the anger, a safety valve 12, safety valve 12 are set on gas transmission line Opening pressure value is preset, when the pressure that set is calmed the anger is more than the preset value of safety valve, casing pressure pneumatic jack opens safety valve 12 Flap is emitted from gas transmission line.Specifically, safety valve 12 is spring micro-open type safety valve.In order to ensure gas unidirectional stream It is logical, and also to which the crude oil that back pressure on petroleum pipeline 14 returns row is avoided to may not flow into the valve of blocking safety valve 12 in safety valve 12 Valve, therefore one ball-and-seat 11 is set positioned at the position of 12 rear end of safety valve on gas transmission line.And it is located at peace on gas transmission line The position of 12 front end of full valve is provided with pressure gauge 8 can observe the pressure size that the set of gas transmission line front end is calmed the anger in real time.
Crude oil flows back in order to prevent, and ball-and-seat 11 is also equipped on petroleum pipeline 14.It is located on petroleum pipeline 14 single The position of 11 front end of stream valve is provided with pressure measurement sampling assemble.Specifically, pressure measurement sampling assemble include pressure gauge 8 and Sample tap valve 10 is provided with sampling valve 9 between the pressure gauge 8 and sample tap valve 10.
When a kind of level pressure tapping equipment that well mouth of oil well set is calmed the anger work of the utility model, sucker rod 1 passes through oil well pump 7 Formation crude oil is pumped into ground, crude oil flows through the oil pipe mouth valve 3 of well mouth oil pipe 2, using the list on petroleum pipeline 14 Valve 11 is flowed, multi-purpose station is finally flowed into;And the annular that the air accumulation separated in crude oil is formed in oil pipe 2 and casing 6 is empty Between middle formation set calm the anger, set pressure gas stream is through sleeve opening valve 5, when the pressure that set is calmed the anger is more than the preset value of safety valve 12, set Calm the anger the flap of open-top safety valve 12, pass through ball-and-seat 11, conveyed in gas transmission line, finally with the crude oil of oil pipe mouth outflow It converges in petroleum pipeline 14 and flows out to multi-purpose station.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change The scope of protection of the utility model is also should be regarded as into replacement.
