Abstract
The utility model relates to a pump both for injecting gas and extracting oil, which is an oil extraction pump used on a thick oil thermal production well, and can be used to inject gas and extract oil; a gas injecting passageway and an oil pumping passageway of the utility model are the same. A pump valve ball of the pump is formed by a shear pin and a shear rod which are suspended on the top of a pump valve ball seat to form the gas injecting passageway. A special coupling is arranged at the upper part of the pump to adjust the length of the oil pumping rod; a safety device with a fixed valve seat is arranged at the lower part of the pump for security protection. When the line of the gas injecting passageway is obstructed, the safety device can automatically open to discharge pressure to maintain an unobstructed line.
Description
The utility model is a notes vapour oil pumping two-purpose pump used on the hot extracting thick oil oil well.It is different with general oil well pump, not only can annotate the vapour operation, the operation of pumping again.
Used a kind of notes vapour oil pumping two-purpose pump on the at present external oil field, it annotates the vapour channels designs in the pump barrel outside.So just make the complex structure of entire pump, and increased seal point again, be difficult for sealing.The pump of this structure requires to use 3, and " above oil pipe so thermal loss is big when annotating vapour, is invested also high.
The utility model provides a kind of notes vapour oil pumping two-purpose pump of new-type structure.This pump will be annotated the vapour channels designs in pump barrel, and will be identical with the oil pumping passage.The pump of this structure, simple in structure, sealing is easy, and thermal loss is little, uses as safe as a house reliable.
Accompanying drawing 1 is a structural representation of annotating the vapour oil well pump.
Accompanying drawing 2 is notes vapour blowing states of annotating vapour oil pumping two-purpose pump.
Accompanying drawing 3 is oil pumping states of annotating vapour oil pumping two-purpose pump.
The utility model is by sucker rod (1); Special box cupling (2); Position shear pin (3); Pump barrel (4); Plunger (5); Annotate vapour joint (6); Under the valve ball (7) that moves about; Shear rod (8); Shear pin (9); Standing valve ball (10); Standing valve seat (11) and safety device (12) form.
The special box cupling (2) that is contained in this pump top can be calibrated the length of sucker rod (1) very easily.
Describe working principle of the present utility model and specific implementation process in detail below in conjunction with accompanying drawing:
At first will annotate vapour oil pumping two-purpose pump is all brought oil well into except that plunger (5) target zone with tubing string.And then will be connected on plunger (5) G.I.H on the sucker rod (1), go up to the position shear pin (3) of special box cupling (2) down and get final product.Utilize the position shear pin (3) of special box cupling (2) when having impact load, can not bear the total weight of sucker rod (1), and be used in the length that function that the effect upper/lower positions shear pin (3) of certain impact load just interrupted is calibrated institute's lower sucker rod.The length of sucker rod utilizes impact force that position shear pin (3) is interrupted after determining, plunger (5) enters pump barrel, but forbids seat to be gone on the notes vapour joint (6) at the bottom of the pump.Standing valve ball (10) is suspended on the top of valve seat (11) by shear pin (9) with it.Plunger (5) is proposed pump barrel (4) top certain distance, so just form one and annotate the vapour passage: the steam that the ground boiler comes is through annotating safety installations (12) → screen casing (the 13) → oil reservoir of steam brake door → oil pipe → special box cupling (2) → pump barrel (4) → notes vapour joints (6) → band standing valve seat (11) again.When annotating vapour end blowing, the working state of annotating vapour oil pumping two-purpose pump is constant, only need close on the ground and annotate the steam brake door, opens the oil recovery gate, can carry out blowing.The oil recovery route is the anti-process of annotating the vapour route, that is: oil reservoir → screen casing → pump → oil pipe → well head → oil recovery gate.Stop-spraying is changeed when taking out, and makes plunger (5) descending, and seat is gone at the bottom of the pump.Percussion shear rod (8) when the following travelling valve (7) on the plunger (5) is descending, make shear rod (8) move downward, under the effect of impact force, shear rod (8) will be contained in its underpart and interrupt from shear pin (9), standing valve ball (10) is dropped on the standing valve seat (11), form the tubing pump state.Can pump after joining over-stroke.The oil recovery route of oil pumping route during with blowing is identical.The safety installations (12) that is contained in standing valve seat (11) bottom of bottom is made up of safety shear pin (14), seal ring (15) and sliding sleeve (16).Safety installations (12) plays the safety protection effect in steam injection process.Caused that by the impurity obstruction steam injection system is obstructed in case annotate vapour joint (6), when line pressure is suppressed certain value, effect down cut bar (8) in vapour pressure is descending, and shear pin (9) is cut off, and at this moment shear rod (8) and standing valve ball (10) together drop on the standing valve ball seat (11).Steam is descending by shearing stalk (8) gap on every side, and continues to act on the standing valve ball (11).At this moment vapour pressure is in continuous rising, when being elevated to certain value, under the effect of this pressure, it is descending that shear rod (8), standing valve ball (10) and standing valve ball seat (11) promote sliding sleeve (16) together, at this moment safe shear pin (14) is cut off, afterwards, shear rod (8), standing valve ball (10), standing valve ball (11) and sliding sleeve (16) are descending rapidly together, seat is gone into screen casing (13), at this moment impurity and steam can inject the stratum by the hole on the screen casing, and is unimpeded to keep annotating vapor circuit.During workover eration, plunger (5) is proposed pump barrel (4), build the pressure with beating liquid in the past oil pipe of cementing truck, when pressure surpasses certain value, safety installations (12) also can be opened draining automatically, at this moment can play the oil drainer effect, and the draining working procedure is identical with pressure leak process.
The utility model has the advantages that:
1. annotate vapour oil pumping dual-purpose pump except the oil pumping function with tubing pump, can also annotate the vapour operation, and be applicable to 1500 meters with the oil well of interior various operating modes.
2. this pump is equipped with special box cupling, can make things convenient for the length of checking sucker rod exactly.
3. this pump has safety installations, has pressure release and draining effect respectively, and service behaviour is safe and reliable.
4. the notes vapour passage of this pump is identical with the oil pumping passage, has simplified pump structure greatly, has reduced cost.
5. this pump only needs 21/2 " oil pipe, economical with materials not only, and also thermal loss is also little.
