Description
Technical field
One beam pumping unit work in combination system formula pumping operation method of the present invention belongs to technical field of oil production engineering,
It is specifically related to a kind of beam pumping unit operation method.
Background technology
In oil recovery process, under the operating mode that stripper well feed flow is not enough, it is often necessary to reduce individual well theoretical displacement.Due to walking beam
Formula oil pumper conventional operation working system is limited to the motion of crank continuous complete cycle, therefore reduces individual well theoretical displacement, can only pass through
Techniques below means:
The first, reduce operation jig frequency, but this mode there is problems in that owing to along with the reduction of oil pumper complete cycle jig frequency, depositing
In the problem that plunger displacement pump leak rate is gradually increased, and, if using conversion system to turn down motor speed, then the driving effect of motor
Rate also can be gradually reduced with the reduction of motor speed；
The second, reduction complete cycle jig frequency is relied on can to produce the problem that plunger leak rate is big and motor drive efficiency is low due to simple, because of
This is under the operating mode that down-hole yield is too low, takes out the motion of working system, i.e. crank continuous complete cycle and shut down work alternately between employing
Mode realizes reducing the purpose of theoretical displacement, but, this mode can produce again following new problem: one is to be turned by stopped status
Entering start to need to carry out under conditions of Attended mode, owing to oil well is many, distance is remote, therefore shuts down and work of starting shooting to be wasted greatly
The manpower and materials of amount；Two be cause 24 hours due to artificial problem of start-up on duty in be difficult to start/stop machine more than twice, and time longer
Between without pumping can cause producing fluid level and down-hole stream pressure fluctuate widely, the growth to well yield and oil-producing formation causes extremely
Adverse influence.
" beam pumping unit based on the motion of crank non-complete cycle is non-to be taken out the patent of invention of Application No. 201510783876.2
Draw operation method ", and Application No. 201510838831.0 patent of invention " based on crank non-complete cycle motion beam type take out
Oil machine dynamically becomes stroke operation method ", all breach beam pumping unit and only exist a kind of operation side of crank continuous complete cycle motion
The technology prejudice of formula, by the non-complete cycle oscillatory motion of crank, it is achieved running without pumping or becoming in the case of non-stop-machine
Stroke runs.If the crank non-complete cycle fortune that the working method moved by continuous for traditional crank complete cycle and above-mentioned two patents propose
Dynamic working method combines according to certain working method, on the one hand not only without reducing complete cycle jig frequency, solves plunger leak rate
Big and that motor drive efficiency is low problem, and owing to oil pumper above ground portion is never shut down, therefore implement without artificial completely
Power-on operation, can substantially save manpower and materials and financial resources consumption that manual site's start causes；On the other hand, this combination type
Pumping operation system can be run with on-demand automatic enforcement repeatedly complete cycle, therefore can avoid long-time without pumping, hence it is evident that reduce dynamic
What liquid level and down-hole stream were pressed fluctuates widely, and advantageously accounts for asking that well yield and oil-producing formation growth adversely affect
Topic.
But, how to implement the combination of both working methods, also there is no related art scheme.
Summary of the invention
For the problems referred to above, the invention discloses a kind of beam pumping unit work in combination system formula pumping operation method,
This method provide a kind of crank complete cycle and run the method for operation combined without pumping operation with non-complete cycle, this mode, it is not necessary to
Reduce complete cycle jig frequency, advantageously account for the problem that plunger leak rate is big and motor drive efficiency is low, eliminate power-on operation demand,
Be conducive to saving because people goes what field conduct power-on operation was caused manpower and materials and financial resources consumption, avoid long-time nothing simultaneously

Step d ', according between take out length cycle timet, determine and take out, at each, the number of times that cycle inside crank complete cycle runsn:
In formula,For downward rounding operation.
In three above embodiment, following 4 needs are also had to illustrate:
The first, in described in step b one day, the practical situation of different time sections down-hole liquid supply speed, is obtained by statistical method, if
Inconspicuous or in confused situation or during taking out week to all the producing fluid level undulate quantity difference of down-hole liquid supply speed change is less demanding,
Take out the cycle between the most desirable equal length and (that is: take out length cycle timetFor definite value) and the number of times complete cycle operation side such as take out in the cycle
Case (that is: takes out the number of times that cycle inside crank complete cycle runs for eachnFor definite value).
The second, take out in the cycle at each, it is desirable to crank completes time-consuming being respectively altogetherComplete cycle run,
And it is a length of time the most totalNon-complete cycle without pumping run, butSize all can arbitrarily adjust, suitable
Sequence can arbitrarily be exchanged.Wherein, the implication that size all can arbitrarily adjust isValue can enter as required
Row changes；The implication that order can arbitrarily be exchanged is for thisnIndividual complete cycle runs and is distributed in this concrete position taking out in the cycle
Put, if continuously, do not do any requirement, can according to actual needs, such as down-hole liquid supply speed, pump condition and the profit of gear-box
The practical situation of sliding demand is adjusted.Such as, it is desirable to completing 10 complete cycles in certain takes out the cycle and run, we can be first
Complete 2 complete cycles to run, then carry out a period of time non-complete cycle and run without pumping, then complete 8 complete cycles operations；We are all right
It is done directly 10 complete cycles to run, then carries out non-complete cycle and run without pumping, until taking out the cycle between the next one.
3rd, in the present invention, as long as being not enough to cause oil pumper to be in the misunderstanding of stopped status to people, for saving energy
The consideration of consumption, non-complete cycle is without allowing time-out in short-term in pumping running.
4th, in actual production process, it tends to be difficult to accurately grasp the quiet deflection of elasticity of each moment polished rod, simultaneously
Also tend to the accurate location being difficult to grasp crank, as the approximation method in a kind of engineering, can be by the bidirectional swinging model of crank
Enclose and be limited in certain scope, i.e. it is believed that crank carry out to be non-complete cycle run without pumping.
