Description

FIELD OF TECHNOLOGY

The technical solution relates to acoustic methods of measurement and control and is intended to determine the liquid level in wells, including oil producers.

BACKGROUND

Known echo sounder for measuring the level of fluid in the well (RU 2282718 from 02.21.2005, IPC ЕВВ 47/04, patent holder LLC "Lozna"). The echo sounder contains a housing, an acoustic pulse generator, a device for receiving acoustic impulses in the form of a piezoelectric microphone, a pressure sensor and a control unit, which is connected to the casing wellhead using a adapter sleeve; The acoustic pulse generator is made in the form of a piezoelectric element equipped with a pulse amplifier in the form of a diffuser and electrically connected to the electric pulse generator. The control unit is equipped with a processor with a predetermined program for automatically adjusting the measurement results, taking into account the propagation velocity of the acoustic pulse from the pressure and composition of the gas medium in the annulus. The wires from the pressure sensor and the piezoelectric microphone are connected to the electric pulse generator and connected to the terminal block of the multicore cable coming from the control unit to the said pulse generator. As a pressure sensor, it is possible to use a MIDA sensor. A piezoelectric microphone can be installed in front of the diffuser, as close to the adapter sleeve as possible. It is possible to place the echo sounder in a quick-folding casing with a hinged lid that can be locked.

The disadvantage of the above sounder for measuring the level of fluid in the well is the inconvenience of using the level measurement, in particular due to the placement of controls directly on the sounder and the lack of remote wireless control.

As the closest analogue of the claimed utility model, you can specify a device for measuring the level of fluid in the well (RU 13391 from 10.28.1999 g, IPC Е21В 47/04, patent holder of Tomsk Scientific and Production and Implementation Society "SIAM") containing a cylindrical body, with one end of which has a threaded sleeve for connecting to the well reinforcement, and on the other is an acoustic signal emitter, a transformer of the reflected acoustic signal into an electric one, characterized in that the housing is made on the contrary a transducer of the base with through-functional openings contains a transducer of the reflected acoustic signal into an electric and additionally introduced pressure transducer, a measurement unit made in the form of printed units oriented along the housing axis, functional elements, a battery for autonomous operation of the device, and an additionally enclosed enclosing rotatable housing , a cylindrical casing and an I / O unit with indication mounted on it, which is connected to the measuring unit after by means of a flexible cable and a detachable contact node, one part of which is connected to the input-output unit, and the other, the reciprocal part is skipped with the possibility of movement in a groove made in the housing.

The disadvantage of the above device for measuring the level of fluid in the well is the inconvenience of use, the increased complexity of the device and low reliability, in particular due to the placement of controls and displays directly on the device and the lack of remote wireless control.

The objective of the technical solution is to create a simpler liquid level sensor in the well, providing ease of use, by introducing wireless control into the design.

IMPLEMENTATION OF THE TECHNICAL SOLUTION

In all of FIG. 1-5 - shows a general view of the level sensor. In this case, the level sensor (1) is designed to measure the liquid level mainly in oil producing wells. The composition of the level sensor includes a coupling (2), which ensures the connection of the base of the housing (3) with the wellhead reinforcement.

Between the base of the casing (3) and the cover of the casing (6), there is a casing (5) made of radiolucent material and covering electronic components such as a controller (18), an accumulator (16), a pressure transducer (17), an indication module, and NFC tag (19).

In this case, the battery (16) provides continuous operation of the level sensor (1).

The pressure sensor (17) converts the pressure in the annulus of the well into an electrical signal.

The controller (18), with an integrated radio channel, provides measurement and storage in non-volatile memory of electrical signals from the pressure transducer and acoustic signal transducer, as well as the transmission of recorded data through the built-in radio channel located in the controller (18), where the latter is located in the casing (5).

The display module and NFC tag (19) is designed to indicate the operation of the level sensor (1) and the battery charge process (16), as well as to establish communication with the sensor via the NFC interface (19).

Information about the operation of the controller (18) and the process of charging the battery (16) is displayed using LED indicators through the windows (11) located on the front panel (10). Windows (11) are made of transparent material.

On the casing (5) from the opposite side from the front panel (10) there is a marking plate (nameplate) (12) for applying the device name, serial number and other information.

On top of the cover of the casing (6) is the clamping nut (7), which holds the cover of the casing (6) and the casing (5).

The acoustic signal generator (8) provides the creation of an acoustic signal due to the short-term release of gas from the annulus of the well.

On the coupling (2) of the level sensor (1) there are two U-shaped handles located coaxially with respect to each other and providing the convenience of screwing the level sensor (1) onto the wellhead reinforcement.

At the same time, from the end of the coupling (2) on the base of the housing (3) are located:

an acoustic signal transducer (13), which provides the conversion of an acoustic signal into an electric one;

- a working through hole (14) leading to a mechanical valve (8), which ensures the passage of gas when opening the valve (8);

- an opening (15) leading to a pressure transducer (17), which provides a pressure measurement inside the coupling cavity (2) using a pressure transducer (17).

The work of the proposed technical solution for measuring the liquid level in the well, including oil and gas, is as follows:

the level sensor (1) is screwed onto the wellhead reinforcement.

When you bring a mobile device (smartphone or other device with an NFC interface) to the level sensor (3), the sensor switches from low power mode to operating mode, the mobile device reads the NFC tag of the sensor (19) and establishes a radio link with the sensor, located in the controller (18). Using a mobile application, the operator can receive current data, as well as control the level sensor (1) via a wireless communication channel.

The claimed technical solution provides ease of use during operation of the level sensor due to the introduction of wireless control in the design, which allows monitoring and control remotely.
