Description
Technical field
This utility model relates to oil exploration equipment technical field, particularly a kind of beam pumping unit.
Background technology
Oil field faces low oil price high cost present situation at present, and oil field enters the middle and late stage of waterflooding extraction, exploitation
The degree of depth and difficulty grow with each passing day.Oil field fluid supply capacity is the most not enough, although oil production equipment is taken by each oil field
Multiple technologies measure, but mechanical oil recovery equipment still occupies leading position.
According to statistics, the quantity of the current mechanical oil well of China accounts for more than the 90% of oil well sum, wherein oil pumper
Oil well accounts for about 80%, and oil production accounts for more than the 75% of total output.
Practice have shown that, beam pumping unit is the type using manufacturing experience more ripe, under low oil price,
Enhancing efficiency by relying on tapping internal latent power reduces investment and reduces maintenance maintenance cost.Oil pumper adjusts jig frequency to change belt and belt pulley, and
Motor or use the higher frequency conversion tank of output investment ratio, all considerably increases cost for oil production.
On the other hand, currently mainly using mechanical type petroleum extractor, service life is longer, and work efficiency is poor
Different relatively big, manually adjust and need to shut down, waste time and energy, impact produces.Its current exploitation work and efficiency are remote
Far do not catch up with the growth of demand, compare other industry and remain multiple backwardness, its production and operation and management
Existence some present situation following:
1. utilization rate of electrical is low: the operational efficiency ratio of oil pumper is relatively low, is only at China's average operating efficiency
25.96%, external average level is 30.05%.
2. manpower expends bigger: includes patrol, look into well etc. and still rely upon manpower.
3. operation record unreliable: artificially collect look into unreliable, the jig frequency of well record calculate unreasonable, go through
History operation or the even no record of ND system problem etc..
4. linkage speed is slow: the information such as the system failure, personnel's invasion, improper start and stop oil pumper carry report
Not in time, the solution occurred therewith is delayed with scheme appearance.
5. operational security problem: sneak current, steal oil condition can not stop completely, it is impossible to general warranty oil field
Yield production capacity maximize.
6. working environment difficulty is improved: as because of means the most advanced, the routine work of workman is often in extreme evil
In bad environment.
