Description
Technical field
The present invention is concretely especially with regard to oil well direct-reading measurement technology about oil field well monitoring technology
One kind is based on signal measurement and wireless transmitting system under the self-powered rod-pumped well of electromagnetic induction electricity generating principle.
Background technique
In petroleum production engineering of today, there is miscellaneous oil production method, but it is main use bar recover the oil
Mode.There is bar to recover the oil and be connected to the oil well pump of thousands of meters of underground using elongated sucker rod, by the pumping unit for being fixed on ground
Sucker rod up and down motion is driven to reach oil pumping purpose.
Sucker rod is the slender rod piece of rod-pumped well, and the polished rod eye of pumping unit is connect on it, under connect oil pumping and pump up transmitting power
Effect.Sucker rod joint length is 7.62,8 or 9.14 meters, and material is usually low-carbon alloy steel by modifier treatment, single
External screw thread is processed at the both ends of sucker rod, then sucker rod will be connected one by one with a kind of standard connector for being box cupling,
Internal screw thread is processed at the both ends of box cupling, and length is generally 100 millimeters, and outer diameter is more slightly larger than sucker rod, passes through pumping in oil pipe in this way
Oil pump piston at oilbearing stratum is connected by beam hanger with the polished rod eye on pumping unit " horse head ", by pumping unit reciprocating motion come
Pump oil.
Now with the drop of oil price, each oil field production unit is increasingly paid attention to producing energy efficiency, such as changes to pumping unit
For frequency control, the adjustable oil pumping frequency is realized, the optimization of water injection pressure and flow to water injection well changes to promote oil production,
But the setting of these current parameters is all based on the experience of operator, in default of the measurement of subsurface environment data, such as fills the water
Water injection pressure and flow are very big in well, and what is pumped in oil well is the very high crude oil of water content, will result in the pole of energy
Big waste.On the other hand, current oil well depth is generally in 2~3 kms or so, and the oil well depth of Karamay, Xinjiang is up to 6
~7 kms, and underground working is sufficiently complex, working environment very severe, is not only influenced by pumping units such as machine, bar, pumps,
It is also directly influenced by sand, wax, gas and water, failure rate is very high, and in order to guarantee that pumpingh well normally produces, extending pumping unit makes
With the service life, the working condition of pumpingh well must be just grasped accurately and in time, diagnose failure present in pumpingh well.
The existing oil well in China in process of production, is monitored almost without to oil well environmental parameter, right at present
Mainly pass through oil production engineering person in the operating condition of pumpingh well to determine the analysis of pumping-unit workdone graphic and the managerial experiences of oil well,
Diagnostic result accuracy is not high, can only nose into situation when situation complexity by extracting all underground sucker rods and oil pipe out, but should
Method is easy to cause misjudgment or the unnecessary test jobs expense of investment, and seldom exist can directly detect underground other
The signal measurement and wireless transmission section of data.Patent network discloses " a kind of fluid-duct-system to generate electricity using piezo technology "
(application number: 201510039957.1) kinetic energy that the device of this power generation may be implemented to flow fluid generation is converted into electric energy,
But be not useful in the environment of oil pumping in oil fields, because there is sucker rod in the pumping pipelines of pumpingh well, sucker rod can't turn
It is dynamic.(application number: being 201610459316.6) by flowing fluid to " a kind of piezo fluid generator " that patent network is announced
Pulsation in the process drives the vibration of piezoelectric membrane to achieve the purpose that power generation, and this device is also not suitable for oil pumping in oil fields
Environment." a kind of sucker rod underground stress signal measurement and wireless transmission section " that patent network is announced (application number:
201310399077.6) although this underground stress signal measurement can be short by devising a test with wireless transmission section
Section is connected to the pressure on sucker rod under testing well but its power supply is powered by way of large-capacity battery, actually well
Down space is very limited, it is impossible to provide the battery of very large capacity, charging is inconvenient, and replacement is only taken out when well workover
Row, once the well workover period is longer, battery may consume, and influence work." the underground seal type load sensing that patent network is announced
Device " (application number: it is 200910072873.2) similar with the former, but it is noted earlier also without solving the problems, such as.It is common from
Power supply signal measurement and wireless transmission section for example patent network announce " a kind of drawing and pressing type vibration energy accumulator " (application number:
201510007482.8) be it is a kind of inertial mass movement driven by vibrating body so that piezoelectric vibrator vibrating power-generation, but this
Invention be it is single-ended be fixed on vibrating body, with oil pumping environment can not be adapted well.In addition to this also there is trial direct
Payout goes down, but electric wire is easily pulled off in oil pumping process, while can also interfere with well-repairing work after being routed.
Summary of the invention
The purpose of the present invention is: it overcomes the deficiencies of the prior art and provide the measurement of pumping unit oil well underground signal and is passed with wireless
Device self-powered may be implemented in defeated system, and structure is simple, easy for installation, adaptable, solves existing in the prior art
It is at high cost and the problem of difficulty of construction is big, different work can be adapted to using different mounting means according to different well depths
Environment.
