Description
Technical field
The present invention relates to a kind of measuring devices, and electrical measurement dress is specifically confessed under the rod-pumped well based on piezoelectric material
It sets.
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 measuring device of data.Patent network disclose " a kind of sucker rod underground stress measuring device " (application number:
201310399077.6) although this underground forces testing device can be connected to sucker rod by devising a test nipple joint
Still its power supply is powered by way of large-capacity battery to pressure under upper testing well, and actually underground space has very much
Limit, it is impossible to the battery of very large capacity is provided, charging is inconvenient, only replacement is taken out when well workover, once well workover is all
Phase is longer, and battery may consume, and influences work.Another kind " the underground seal type load sensor " (application that patent network is announced
Number: 200910072873.2) it is with the former similar, but it is noted earlier also without solving the problems, such as.Common confession electrical measurement
(application number: being 201510007482.8) that one kind passes through vibration to " a kind of drawing and pressing type vibration energy accumulator " that device such as patent network is announced
Body drives inertial mass movement so that piezoelectric vibrator vibrating power-generation, but the invention be it is single-ended be fixed on vibrating body, with
Oil pumping environment can not be adapted well.In addition to this direct payout of trial also goes down, but it is electric in oil pumping process
Line is easily pulled off, while can also interfere with well-repairing work after being routed.
