Description
Technical field
Beam pumping unit work in combination system formula pumping operation method of the present invention belongs to technical field of oil production engineering, specifically
It is related to a kind of beam pumping unit operation method.
Background technology
In oil recovery process, under the insufficient operating mode of stripper well feed flow, it is often necessary to reduce individual well theoretical displacement.Due to walking beam
Formula pumping unit conventional operation working system is limited to the continuous complete cycle movement of crank, therefore reduces individual well theoretical displacement, can only pass through
Following technological means：
The first, operation jig frequency is reduced, but this mode has the following problems：Due to the drop with pumping unit complete cycle jig frequency
It is low, there are problems that plunger pump leak rate gradually increases, moreover, if turning down motor speed using conversion system, motor
Drive efficiency can be also gradually reduced with the reduction of motor speed；
The second, due to relying on reduction complete cycle jig frequency will produce merely, plunger leak rate is big low with motor drive efficiency to ask
Topic, therefore under the too low operating mode of underground yield, working system is taken out using, i.e. the continuous complete cycle movement of crank and shutdown is alternate
Working method reduces the purpose of theoretical displacement to realize, still, this mode will produce following new problem again：First, by shutdown shape
State is transferred to booting and needs to carry out under conditions of Attended mode, and since oil well is more, distance is remote, therefore wave is wanted in shutdown and booting work
Take a large amount of manpower and materials；Second is that since artificial problem of start-up on duty causes to be difficult to start/stop machine more than twice in 24 hours, and compared with
Hydrodynamic face and underground can be caused to flow fluctuating widely for pressure without pumping for a long time, the development of well yield and oil-producing formation is caused
Extremely disadvantageous influence.
Application No. is 201510783876.2 patents of invention《The non-pumping of beam pumping unit based on the non-complete cycle movement of crank
Draw operation method》, and application No. is 201510838831.0 patents of invention《Beam type based on the non-complete cycle movement of crank is taken out
Oil machine dynamic becomes stroke operation method》, breaching beam pumping unit, there is only the continuous complete cycles of crank to move a kind of operation side
The technology prejudice of formula is realized in non-stop-machine no pumping operation or is become by the non-complete cycle oscillatory motion of crank
Stroke is run.If the non-complete cycle of crank that the working method of the continuous complete cycle movement of traditional crank is proposed with above-mentioned two patents transported
Dynamic working method is combined according to certain working method, is on the one hand not only not necessarily to reduce complete cycle jig frequency, is solved plunger leak rate
Big and low motor drive efficiency problem, and since pumping unit above ground portion is never shut down, therefore it is not necessarily to artificial implement completely
Power-on operation can obviously save manpower and materials caused by manual site's booting and financial resources consumption；On the other hand, this combined type
Pumping operation system the multiple complete cycle of automatic implementation can be run on demand, therefore can be to avoid long-time without pumping, hence it is evident that be reduced dynamic
What liquid level and underground stream were pressed fluctuates widely, and advantageously accounts for asking what well yield and oil-producing formation development adversely affected
Topic.
However, how to implement the combination of both working methods, there are no related art schemes.

Step d ', cycle time length t is taken out between, determine the frequency n that the operation of period inside crank complete cycle is taken out at each：
In formula,For downward rounding operation.
In three above embodiment, also following 4 points need to illustrate：
The first, described in step b in one day different time sections underground liquid supply speed actual conditions, obtained by statistical method,
If underground liquid supply speed changes unobvious or hydrodynamic surface wave momentum differences requirement in confused situation or to all pumping during all
It is not high, then take out the period (i.e. between desirable equal length：Between to take out cycle time length t be definite value) and take out equal numbers complete cycle fortune in the period
Row scheme is (i.e.：The frequency n that the operation of period inside crank complete cycle is taken out between each is definite value).
The second, it is taken out in the period at each, it is desirable that it is respectively t that crank, which is completed to take altogether,1、t2、…、tnComplete cycle operation, with
And time-consuming total duration is tNon- complete cycleNon- complete cycle run without pumping, but t1、t2、…、tnSize can arbitrarily adjust, sequence
It can arbitrarily exchange.Wherein, the meaning that size can be adjusted arbitrarily is t1、t2、…、tnValue can carry out as needed
Change；The meaning that sequence can be exchanged arbitrarily is the specific location being distributed in for this n complete cycle operation in this pumping period,
It is whether continuous, do not do any requirement, can according to actual needs, such as underground liquid supply speed, pump condition and gear-box lubrication
The actual conditions of demand are adjusted.Such as, it is desirable that 10 complete cycle operations are completed within some pumping period, we can be first complete
It is run at 2 complete cycles, then carries out a period of time non-complete cycle and run without pumping, then complete 8 complete cycle operations；We can also be straight
10 complete cycle operations of completion are connect, non-complete cycle is then carried out and is run without pumping, the period is taken out until next.
Third, in the present invention, as long as being not enough to the artificial misunderstanding for being in shutdown status at pumping unit, for saving energy
The considerations of consumption, non-complete cycle is without the pause allowed in pumping operational process in short-term.
4th, in the actual production process, it tends to be difficult to accurately grasp the quiet deflection of elasticity of each moment polished rod, simultaneously
The accurate location for being difficult to grasp crank is also tended to, it, can be by the bidirectional swinging model of crank as the approximation method in a kind of engineering
Enclose limitation in a certain range, you can think crank progress is that non-complete cycle is run without pumping.
