Definitions
- the utility model relates to measuring technology, in particular to a device for determining the pressure and temperature of the medium in a well, and can be used to determine the physical parameters in the well.
- a device for measuring pressure and temperature in a well is known (RF patent for invention No. 2149993, publ. 27.05.2000 Bull. No. 15), containing a pressure transducer, a four-wire communication line, a current source, a multi-channel analog-to-digital converter connected to a microprocessor unit.
- the disadvantage of this device is the presence of an analog-to-digital converter, which introduces additional noise when converting the value of an analog value into a digital value to be stored in the instrument's memory, which affects the measurement accuracy.
- a device for measuring physical parameters in a well is known (RF patent for invention No. 2013537, publ. 05/30/1994), containing a pressure indicator connected to a device for measuring pressure, a source of working medium connected to a device for measuring pressure, a device for measuring temperature, a temperature sensor and a temperature indicator connected respectively to the input and output of the temperature measuring device.
- a device for measuring physical parameters in a well is known (RF patent for utility model No. 49110, publ. 10.11.2005 Bull. No. 31), containing a housing in the form of a cylinder, which houses a temperature sensor, a pressure sensor and batteries.
- the disadvantage of this device is the influence of the heating temperature of the operating electronics on the results of measuring the physical parameters of the well by sensors.
- the closest in technical essence is a device for measuring physical parameters in a well (RU 176710), containing a body in the form of a cylinder, which houses a temperature sensor, a pressure sensor and batteries.
- the device is equipped with a measuring head with a protective cap with holes for the medium, connected to the body and to each other by a threaded connection, inside the measuring head there is a pressure sensor connected to the media separator and made in the form of a low-frequency quartz resonator, at the end of the measuring head there is a platinum temperature sensor made in the form of a temperature probe, and in a sealed housing, there is a timer, an electronic board for converting signals from pressure and temperature sensors, which has a non-volatile memory for storing data, and batteries.
- the technical result is to increase the performance of the device.
- the device for measuring the physical parameters of the well contains a cylindrical body, a measuring head, a protective cap with holes for the medium, a pressure sensor, a media separator, a temperature sensor, made in the form of a temperature probe, a timer, an electronic board for converting signals from pressure and temperature sensors and batteries, the body of the device is made of Inconel 718 material, and the media separator is made of Inconel 625 material.
- Fig.1 shows the device in section.
- the device for measuring the physical parameters of the well contains a cylindrical body 1, a measuring head 2 with a protective cap 3 with holes 4 for the medium, a pressure sensor 5 made in the form of a low-frequency quartz resonator, a media separator 6, a temperature sensor 7 made in the form of a temperature probe, a timer 8, electronic board 9 for converting signals from pressure and temperature sensors and batteries 10.
- the housing contains a temperature sensor, a pressure sensor, batteries, a timer, an electronic board for converting pressure and temperature sensor signals.
- the head and the protective cap are connected to the body and to each other by a threaded connection.
- the pressure sensor is located inside the measuring head.
- the temperature sensor is located at the end of the measuring head.
- the case of the device is made of material - Inconel 718 (Inconel 718).
- the use of this material for the body made it possible to increase the maximum working pressure of the device to 100 MPa (at 60 MPa for analogues).
- the pressure sensor is made on the basis of a low-frequency quartz resonator, which changes the frequency of natural oscillations under the action of the external pressure of the environment applied to it.
- This type of sensor has an output signal in the form of quasi-stable rectangular pulses, which makes it possible to digitize the useful signal without the use of an analog-to-digital converter, by counting the duration of the period of oscillation of the frequency output signal of the pressure sensor.
- the connection of the pressure sensor with the media separator ensures minimal signal distortion and isolates it from the influence of the aggressive action of the downhole fluid, which increases the reliability of pressure measurement in the well.
- the device has a measurement resolution of at least 20 Pa and a noise standard deviation level of at least 20 Pa, which makes it possible to reliably record small pressure changes in the well of at least 60 Pa without using additional mathematical processing methods data and reduce the time of observation with the pulse-code method of research.
- the measurement range ranges from 1 to 600 atm.
- the media separator is a diaphragm/bellows separator made of Inconel 625 (Inconel 625) material, which increases the corrosion resistance of the pressure transmitter.
- the device works as follows.
- the pressure sensor 5 is installed inside the measuring head 2 and communicates with the environment through a membrane/bellows separator 6 media, which transmits the ambient pressure to the pressure sensor 5 with minimal distortion, while isolating it from the influence of the aggressive impact of the well fluid.
- Temperature sensor 7, placed outside the body in the form of a temperature probe reliably measures the temperature of the well due to the absence of the influence of changing temperature and the parasitic thermal error from the thermal radiation of the operating electronic board 9.
- the platinum temperature sensor is mounted with thermal paste, by stuffing it into the capillary, when the temperature sensor is placed there.
- a protective cap 3 with holes 4 for the medium makes it possible to ensure the contact of the sensors with the downhole environment and at the same time protects them from external mechanical influences, ensuring the reliability of pressure and temperature measurements in the well.
- the signals of both sensors 5 and 7, based on the conversion of the pressure and temperature of the quartz resonator into frequency in the form of sequences of pulses with a certain repetition rate, are fed to the electronic board 9, where the primary signals of the pressure and temperature sensors are converted into a form convenient for processing and with the help of a temporary timer 8, they are linked to real time.
- the temperature and pressure values are stored in the non-volatile memory of the data storage device. After carrying out the necessary measurements and lifting the device to the surface, its case is opened and connected to a computer using an interface cable; the accumulated data is submitted for analysis and display.
- the non-volatile memory of the device and the capacity of the batteries are chosen so that they allow detailed measurements of temperature and pressure in the well with a resolution of 1 s continuously for 3 months.
- the mode of operation of this device allows you to simultaneously conduct long-term monitoring of changes in temperature and pressure in the well.
