Description
Technical field
The invention belongs to oil well test and control technology field, is specifically a kind of oil well test and control system, is related to list
The remote control of the metering of well production liquid, data transfer management and field device operation.
Background technology
Oil well test and control system are in oil field, the metering of stripper field Liquid output and measurement aqueous in real time,
The data of measurement are transmitted to oilfield supervisory room by telecommunication network at set time intervals at the same time, and receive oilfield supervisory
The control signal of room, controls the stopping of pumping unit, starts.
The method for production metering of oil wells that domestic each oil field uses at present is mainly the following：
● horizontal elevated tank strapping；
● glass tube oil gauge method；
● build-up of fluid method；
● power graph method；
● electrode liquid level gauging；
● oil tank level mensuration；
● pipeline flow mensuration.
Horizontal elevated tank strapping and glass tube oil gauge method, since metering method is more original, labor strength is big, accurate
Exactness is low, and poor reliability, has been rarely employed now.
Build-up of fluid method and power graph method metering, since both metering methods need substantial amounts of oil well production data, it is difficult to
Accomplish Computer Automatic Recognition indicator card, and need some empirical parameters that there is larger human factor, cause measurement error
Larger, using effect is unsatisfactory.
Traditional electrode liquid level oil meter amount method, is the liquid volume by measuring, is converted using separator constant
Or the conversion of differential pressure liquid level, obtain producing liquid-tight degree, so that convert to obtain Liquid output, but since the otherness for producing liquid-tight degree is very big,
Thus this method not only manually takes, but also the error of Liquid output measurement is big.
The shortcomings that current existing common oil tank level mensuration, the technology, includes：1., hand-dipping mensuration application in labor
Fatigue resistance is big, and there is also insecurity；2., float level meter is due to the friction of pulley, disc spring mechanism and mechanical counter
Its reliability of power is poor；3., servo-type level meter measurement it is expensive, can not apply oil field promote；4., magnetostrictive liquid level apparatus
Corrosion-vulnerable is held in the easy fluid to be measured contact of mensuration, while variable density easily causes larger measurement error；5., other are such as floating
Son movement is easily by card, differential pressure type liquid level measurement overload capacity is strong, ultrasonic liquid level measuring result is affected by environment larger.
For pipeline flow mensuration, due in, its Liquid output of low yield pumpingh well it is small, fluid can not full-section pipe-flow in pipeline
It is dynamic, and fluid flowing is intermittent big, therefore be also unable to reach and oil well liquid-producing is accurately measured.
Had the disadvantage that in generally existing oil well liquid-producing measurement technology application：
1) crude oil with its viscosity of season is different, especially northern winter crude oil into bulk, the prior art to its liquid level without
Method accurately measures.
2) water content in crude oil changes with production process, i.e., the density of oil storage pot liquid also changes therewith, and original technology exists
Larger error can be produced when measuring oil tank liquid weight.
3) shape of oil well oil storage tank is different, and original technology has the shortcomings that very big when liquid weight is produced in metering.
4) in, the change of low-producing pumpingh well its oil tank level it is slow, influenced by measurement accuracy, the current oil well is
No production liquid None- identified.
5) original oil tank level technology can not weigh the water status of current state oil well liquid-producing.
6) original technology can not finely identify the historical record of oilwell produced fluid amount change.
7) instrument price containing water gaging is expensive, few then tens of thousands of, at most ten tens of thousands of, this individual well large number of to oil field
Saying to realize.
