Abstract
An original sliding vane rotary flowmeter uses the rotation of the outer cover of a magnetic steel to drive a mechanical gear mechanism for counting. The utility model makes use of the characteristics of the original sliding vane rotary flowmeter to improve a meter head, in order to be applicable to the field environment. Concretely speaking, an original mechanical counter and associated components are removed, an original magnetic shaft coupling device is used as a magnetic pulse generating device, pulse signals have synchronous rotation speed with the original sliding vane rotary flowmeter, and a portable magneto-dependent sensor and a counter are used to measure and record the number of the pulses. Thus, the number of the pulses generated in unit time is multiplied with the originally marked volume per rotation, and then the individual well liquid producing capacity in unit time can be obtained. If the individual well air content is high, a wellhead air eliminator can be installed, or the pulse parameter can be modified according to the fuel-air ratio.
Description
The utility model relates to a kind of well mouth of oil well flow measurement device.
In the present one-well metering in oil field, adopt separation vessel, rotz flowmeter etc. usually, but can't solve two mouthfuls of wells or connection in series-parallel flow process more than two mouthfuls and the one-well metering problem that influenced by air content.The metering of these wells at present all is to close down flatly or several mouthfuls of well amount a bite well yields, stop this a bite well again and measure another mouthful well or several mouthfuls of well yields, bring a lot of inconvenience for post workman's operation, labour intensity strengthens, and the more important thing is and close down oil well, not only can influence per-well production but also have part wax content height, the low oil well of oil temperature to be easy to be stuck, once influence one ton of output if every mouthful of well stops, opens every day, economic loss is very considerable.
The purpose of this utility model is for a kind of measuring instrument that does not stop production and don't be damaged at the connection in series-parallel individual well is provided, and meets oil well one-well metering standard, and is easy to operate, the measuring apparatus of dependable performance.
The technical solution of the utility model is achieved in that the characteristics of utilizing former blade flowmeter, and former mechanical counter is changed into the electromagnetic induction electronic counter, and its special character is: (1), magnet coupler produce the magnetic-pulse signal under liquid effects; (2), magneto-dependent sensor is in pulse signal collection, amplification and the input electronic calculator; (3), measurement and recording section be detachable, what stay well head is a complete airtight flowmeter.
Advantage of the present utility model:
(1), utilized the one-piece construction of former national approved product as far as possible.
(2), adopt portable magneto-dependent sensor to accept and handled the magnetic strength pulse signal, and be input to and count processing in the pocket calculator.
(3), since measurement count partial volume I and flowmeter body portion from, so can prevent to destroy suitable open-air liquid meter.
(4), simple to operate, do not have consumable accessory and agent structure that the regular manufacturer production of standard is arranged, with low cost.
Accompanying drawing is a composition structure diagram of the present utility model.
Below in conjunction with accompanying drawing furtherly the name (embodiment).
Blade flowmeter (11) rotates under the promotion of liquid and exports by main shaft (1), under main shaft (1) drives, the pulsactor (2) that magnet steel (4) are housed also rotates thereupon, rotate a week (360 °), the magneto-dependent sensor (7) in the measured hole (5) on the spacer that is made of non-magnetic shielding material (3) and the guard shield (6) can be at the outside induction monitoring of spacer (3) to the magnetic-pulse signal.This signal is treated to be input in the counter (10) by lead (8), interface (9), and paired pulses is counted.Then, the pulse signal volume flow radix of demarcating with former manufacturer production multiply by the pulse number in the unit interval again, just obtains in the unit interval and the production fluid amount of whole day.
Air separator can be installed or according to oil-gas ratio corrected impulse parameter at the high oil well of oil-gas ratio.
As can be seen, the utility model comes down to bipartite, and promptly the on-line measurement magnetic-pulse that is made of the blade flowmeter main body part takes place and is made of portable pulse monitoring counting, calculating section that magneto-dependent sensor and counter etc. constitutes.Because online measurement magnetic-pulse generation part globality, sealing and soundness is all better, movement-less part exposes, thus adapt to the needs of field extreme environment, and antitheft, anti-damage ability is strong.
Claims (3)
- A kind of detachable magneto-electric induction blade flowmeter of being made up of blade flowmeter (11), the pulsactor (2) that magnet steel (4) are housed and magneto-dependent sensor (7) and counter (10) is characterized in that:(1), pulsactor (2) is on the main shaft (1) that is fixed on blade flowmeter (11);
- (2), pulsactor (2) outside is equipped with spacer (3), and the guard shield (6) of band measured hole (5) is equipped with in the outside of spacer (3);
- (3), the magneto-dependent sensor (7) that is linked with counter (10) can insert measured hole (5) and contact with spacer (3).
