Specific implementation mode
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, technical solutions in the embodiments of the present application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.Based on the embodiment in the application, this field is common
The every other embodiment that technical staff is obtained without creative efforts should all belong to the application protection
Range.
Refering to what is shown in Fig. 1, the sucker rod pump hoisting system of the application embodiment may include pumping unit 1, the pumping unit 1
On be connected with polished rod 2, the lower end of the polished rod 2 is connected with sucker rod 3 across production tree, and the lower end of the sucker rod 3 is connected with
Oil well pump;The sucker rod 3 includes upper sucker rod 31 and lower sucker rod connected to it 32.In use, the pumping unit 1 is with institute
The up and down motion of polished rod 2 is stated, is moved up and down to move sucker rod 3 described in synchronous belt.
In one embodiment of the application, one of the upper sucker rod 31 and the lower sucker rod 32 can be that carbon fiber is taken out
Beam hanger;In this way, since carbon fibre pumping rod has light weight, the features such as intensity is big, thus sucker rod pump hoisting system can be reduced
Dead weight, reduce oil pumping machine polished rod load.
In one embodiment of the application, the upper sucker rod 31 can be carbon fibre pumping rod, and the lower sucker rod
32 can be metal sucker rod (such as pumping rod made by steel etc.), in this way, the lower sucker rod 32 simultaneous can play counterweight effect, to
Advantageously ensure that 3 downlink of sucker rod is smooth.
In another embodiment of the application, the carbon fibre pumping rod can also replace with graphene sucker rod etc., together
Sample can reach similar technique effect.
In one embodiment of the application, the upper sucker rod can have specific length ratio with the lower sucker rod, with
So that not only enough reducing by 3 load of sucker rod, but also can ensure that 3 uplink and downlink of sucker rod is smooth, i.e., ensure sucker rod 3 can uplink and downlink it is suitable
Under the premise of profit, 3 load of sucker rod is reduced as far as possible.
Shown in continuing to refer to figure 1, the oil well pump includes the oil pump sleeve 4 being fixedly connected with oil pipe 6, the oil well pump
The plunger 5 being connect with the lower sucker rod 32 is equipped in pump barrel 4.Travelling valve (or being travelling valve) can be equipped in the plunger
(being not drawn into figure) in the application embodiment, unlatching and the pass of the valve ball and valve seat of the travelling valve are realized using pressure
It closes.In addition, 4 bottom of the oil pump sleeve is also provided with fixed valve (or being standing valve) (being not drawn into figure).Equally,
In the application embodiment, the open and close of the valve ball and valve seat of the fixed valve are realized using pressure.
In addition, during realizing the application, the inventor of the present application discovered that:Conventional sucker rod pump hoisting system is in deep-well
It is had the following problems in oil pumping technique:
A, wastage significantly increases, and the pressure difference up to number 10Mpa at oil pump plunger piston both ends is acted in deep-well, using routine
When conventional pump, since the effect of pressure will be such that the annular space between oil well pump and plunger further increases, to make wastage into one
Step increases, and influences the pump efficiency of oil well pump;
B, common oil well pump integral strength is low, is easily damaged under bad working environments and exists with underground break-off accident, conventional pump
Sorting is not suitable for deep-well in heat treatment and structure;
C, due to the swollen pump phenomenon being happened in deep-well, fatigue damage easily occurs for conventional pump.
To solve the above problems, in conjunction with shown in Fig. 2, in one embodiment of the application, the oil pump sleeve 4 can wrap
Inner cylinder 41 is included, outer tube 42 is cased on the inner cylinder 41, the gap between the outer tube 42 and the inner cylinder 41 forms pressure chamber, institute
Stating the lower end of pressure chamber can be sealed by end ring plug 43.To form a unique self-styled pump barrel of waterpower.In this way, upper
In stroke, the fluid column static pressure in tubing string acts on 42 outer wall of outer tube that (head of liquid acts on pump barrel in conventional pump upstroke
On inner wall, as a result, annular space is forced to increase, wastage is made to obviously increase), under the effect of the pressure, inner cylinder 41 and plunger 5
Between gap reduce, reduced so as to reduce because of caused by leakage the efficiency of pump;In down stroke, due to putting down for external and internal pressure
Weighing apparatus, can eliminate swollen pump phenomenon, to be obviously prolonged the fatigue life of pump barrel.
According to relevant criterion, the thickness that is recommended as of inner cylinder 41 is 6.35mm, but for small pump, is transporting, going into the well
In the process easily occur inner cylinder 41 bending, local radial deformation etc. failures, to make pump in underground work plunger pull it is dumb,
The accident frequencies such as beam rating increase, holddown increase.In one embodiment of the application, the thickness of the inner cylinder 41 can increase to
10mm increases rigidity so as to play, reduces the purpose of local deformation.In this way, along with unique waterpower self-sealing pump barrel is stated
Structure so that the oil pump sleeve 4 of the application embodiment eliminates swollen pump phenomenon in addition to having many advantages, such as to be substantially reduced wastage
Outside, also there is the stress for improving inner cylinder 41, its service life can be extended, increase the functions such as oil well pump integral strength.
In one embodiment of the application, described to have oil well pump may include Anti-sway wear-pump oil pump, and deep journey is pumped through to reduce
Middle tube rod friction phenomenon extends pump detection period.Above-mentioned Anti-sway wear-pump oil pump can be (such as anti-by installing corresponding anti-bias mill apparatus
Bias wearing joint hoop, centralizer etc.) it realizes.
It should also be noted that, the terms "include", "comprise" or its any other variant are intended to nonexcludability
Including so that component or equipment including a series of elements include not only those elements, but also include not clear
The other element listed, or further include for this component or the intrinsic element of equipment.In the feelings not limited more
Under condition, the element that is limited by sentence "including a ...", it is not excluded that including the element component or equipment in also
There are other identical elements.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with
The difference of other embodiment.
Above is only an example of the present application, it is not intended to limit this application.For those skilled in the art
For, the application can have various modifications and variations.It is all within spirit herein and principle made by any modification, equivalent
Replace, improve etc., it should be included within the scope of claims hereof.
