SYSTEM FOR STATIC SOUND SENSING

The technical solution relates to devices for static sounding of the soil and can be used in monitoring systems for drilling in soil strata of wells.

Known devices for static sounding of the soil (see, for example, 7), as a rule, contain an immersion probe equipped with sensors for soil parameters, as well as a measuring device and recording equipment located in the ground part.

Known designs of soil sensing systems 1-6 and / or systems for controlling well drilling traditionally include a cabled downhole (immersed) device and ground processing equipment. Examples of such devices are: a downhole telemetry system 6, a geosteering complex for working in subterranean formations 5, a control system for the development of subsoil formations 4, a cable telemetry system 3 for controlling well drilling, and a device 2 for separating producing oil formations in a well.

However, the cable connection of the ground and borehole parts of devices 2-6 limits their functionality, and, in some cases, is not reliable enough.

Known information-measuring system 1 for geophysical research of wells, adopted as a prototype, includes a ground-based device and a downhole (immersed) device connected

IPC: E 02 D 1/00, E 21 V 44/00

geophysical cable. In this case, the data measured by the sensors in the immersion device are processed in a microprocessor.

The prototype system 1, as well as analogs 2-6, is limited in functionality due to the cable connection of the immersed and ground parts, which could be eliminated by introducing a wireless communication line between them.

The essence of the proposed technical solution is to create a system of static sounding of the soil (or a monitoring and control system for drilling in soil strata of wells) with a wireless communication line between its surface and submersible (well) modules.

The main technical result is the expansion of functionality when using a wireless communication line, and also improving the reliability of information transfer from the immersed module to ground-based data processing equipment.

The technical result is achieved as follows.

The system for static sounding of the soil, contains a submersible module, connected through a communication line with the ground module.

A distinctive feature of the system is that the communication line is made in the form of a wireless communication line (WLAN), for example, a radio communication line. Moreover, the immersion module includes a group of sensors, the outputs of which are connected to the input of the analog-to-digital converter () through the amplifier, adder, and switch, the ADC input-output is connected to the microprocessor input-output, the input-output of which is connected to the BLS transceiver input-output, and the ground the module includes serially connected BLS transceiver, a decoder and a personal computer of the Notebook type, which includes programmable units for recording measurement data, a processing unit, and a display unit for measuring and information.

Moreover, the system is characterized in that the group of sensors of the immersed module includes sensors for resistivity, lateral friction, humidity, temperature, radioactivity and other soil parameters.

The drawing shows a structural diagram of the system.

The system for static sensing of the soil contains an immersion module 1 and a ground module 2. The immersion module 1 includes a group of sensors 3, an amplifier 4, an adder 5, a switch 6, an ADC 7, a microprocessor 8, and a radar transceiver 9. The ground module 2 includes a BLS transceiver 10, a decoder 11, and a Notebook type personal computer 12 as part of programmable measurement data recording units 13, processing unit 14, and measurement information display unit 15.

The work of the proposed system is similar to the work of the known devices 1 to 6 with the difference of the communication line between the submersible and ground modules 1 and 2, which is made in the form of a BLS, for example, a radio communication line.

The soil (well) parameters measured by the sensors 3 through the amplifier 4, the adder 5 and the switch 6 are fed to the input of the ADC 7, where they are converted to digital form, and then to the microprocessor 8, where they are stored. In static soil sensing, the measured values are resistivity, lateral friction, humidity, temperature, radioactivity and other soil parameters. In the case of using the system for monitoring and controlling drilling in soil formations, the set of measured parameters is determined by the specifics of these works (see, for example, 3). On command from the ground module 1, the measurement data are transmitted via the WLAN between the transceivers 9 and 10. The measurement data received by the transceiver 10 of the ground module 2 are transmitted to the decoder 11 and then to the personal computer 12, in the programmable units of which the data is recorded

measurements (block 13), their processing (block 14), as well as the display of measurement information (block 15).

Thus, the constructive implementation of the system allows you to implement a WLAN between its ground and submersible modules, which expands its functionality and also increases the reliability of information transfer.
