The invention relates to the field of oil and gas production, in particular, to inspecting wells and transmitting information about the results of monitoring the parameters of the oil and gas production process, and can be used to take readings and control the work being done on oil and gas wells and oilfield equipment that are not equipped with or partially equipped with automated process control systems (ACS TP).

State of the art

A well-known system for monitoring the operation of wells with two-way communication (RF patent No. 2093897, class IPC G08C 17/00, G08C 21/00, publication date 10/20/1997) relating to the technique of measuring and transmitting information about the results of monitoring parameters characterizing the work complex technical equipment used to transmit alarms and to monitor the operation of wells from a control room. The system for monitoring the operation of two-way communication wells consists of a transmitting device containing a flow meter, a unit for generating a well number, a transmitter, a transmitter antenna, a receiver antenna, a transceiver device containing a receiver, a modulator, a line interface unit, a power supply unit for a transceiver device, communication lines, a receiving device containing a unit for extracting information pulses, a microprocessor, an indication unit, a storage device, a power supply unit of the receiving device. The system is equipped at the individual information point with a signal switching unit, a receiver and a well number recognition unit, at a group information point a signal switching unit, a transmitter, a demodulator, an interface unit with a line from the transmission side, a control unit with a seal unit, a well number and group number generation unit information point and dispatcher console. The disadvantages of this system is the stationary location of the system, the need to incur additional costs for the maintenance of communication equipment and instrumentation.

A known system for operational monitoring of the operation and diagnostics of ground and underground equipment of pumping wells (options) (RF patent No. 17564, publication date 10.04.2001, class IPC Е21В 47/00), including a sensor of at least one parameter the phase circuit of the electric motor of the pumping unit, connected to the signal processing and indication means, while the specified sensor is made in the form of a remote measurement sensor of the specified parameter of the phase circuit of the specified motor. The control system also includes a device for measuring and recording data containing a microcontroller and an analog-to-digital converter. The disadvantages of this system is the stationary location of the system, the need to incur additional costs for the maintenance of communication equipment and instrumentation.

A known device for monitoring the state of a working gas or oil well (RF patent No. 2378507, class IPC ЕВВ 47/00, G08C 17/00, published date 27.06.2008), containing a controllable power supply, microprocessor, including analog-to-digital and digital-to-analog converters , wellhead parameter sensors, sensor signal switch, non-volatile memory unit, radio modem, nonius block, one input of which is connected to the output of the switch, the other input is connected to the output of the digital-to-analog converter, and the output is connected to the input of the second analog-to-digital the converter, the microprocessor is designed to provide, after its programming and commissioning, a one-time control transmission of parameters in the form of an SMS message both by the main telephone number and by the additional number. The microprocessor is designed to provide, in the event of a temporary lack of communication, the transmission of non-transmitted data the next time the radio modem is turned on. The microprocessor is designed to provide, when the value of any wellhead parameter of the emergency threshold is reached, extraordinary data transfer by the main telephone number. The disadvantages of this system is the stationary location of the system, and as a result, the need to bear the additional costs of servicing communication equipment and instrumentation. Also, using SMS messages as a signaling leads to a limitation of the size of the transmitted information, since the maximum size of an SMS message is 140 bytes.

A known device for monitoring wellhead operation parameters of gas and gas condensate wells (RF patent No. 109212, published on 10/10/2011, class IPC Е21В 47/00, G08C 17/00), made in the form of a pressure gauge-thermometer with autonomous power (lithium battery) and the ability to transmit data over the air through an antenna connected to the connector. The device consists of a main unit, in which are located: a pressure sensor, a controller board and a radio modulator, plus and minus contacts of the battery power, the casing of the device, the battery compartment housing. The main unit casing, designed for outdoor installation (degree of protection against dust and moisture IP65), connects a temperature sensor and an antenna of the RK through the connectors. RTP-4 can be equipped with both conventional (whip) and directional antennas. The first ones provide stable communication at a distance of 4-5 km in direct visibility conditions, the second (more bulky) can increase the range of the Republic of Kazakhstan to 12-15 km, provided that there are directional antennas at both ends. The device allows you to control the wellhead thermobaric parameters of production (non-electrified) wells of fields that are not equipped with automated systems for collecting and transmitting technological information, and in combination with thermobaric parameters at the entrance to the ZPA GSK, it will allow you to make operational decisions when the performance of the wells and GSK deteriorates. The disadvantages of this system is the stationary location of the system, and as a result, the need to bear the additional costs of servicing communication equipment and instrumentation. Frequent battery replacement will also be required with an increase in the frequency of polling instrumentation, due to the high energy costs of transmitting information over a radio communication network.

The closest technical result to be achieved is a system for monitoring work on a well (RF application No. 2005137724, publication date 27.04.2006, class IPC EV21/02), which includes a mobile vehicle that contains a monitor for collecting data and at least one tool for monitoring well operation;

at least one transducer combined with an appropriate tool to obtain a parameter that carries information about the operation of the well, each transducer sends an electronic signal to the monitor to collect data; portable non-volatile storage device associated with the monitor for collecting data, and the storage device is configured to physically remove from the monitor to collect data for moving it to a predetermined location.

The disadvantages of this system are the availability of additional equipment requiring installation, and as a result, additional costs for maintenance and relocation of equipment.
