Description

The invention relates to the field of drilling engineering and exploration wells, in particular to systems for monitoring technological parameters of the drilling process, namely to a system for monitoring technological parameters of the drilling process based on a self-propelled drilling rig, and is intended to control, register, display, record, store and transfer current parameters of the drilling process via communication means to control the drilling process.

A device for monitoring the drilling process is known, containing devices for measuring the weight of a drilling tool, for measuring the load on the bottomhole, for measuring the pressure of the drilling fluid, for measuring the torque on the rotor, for measuring the forces on the key, for measuring the density of the drilling fluid and for measuring the flow rate of the drilling solution, power supply unit, signal processing unit and observation unit (RU, application No. 94011511, Е21В 44/00, Publ. 27.01.1996). Each device for measuring the corresponding parameter has a primary transducer. The signal processing unit has intermediate electronic normalizing converters. Each intermediate normalizing converter is electrically connected to the corresponding primary converter. The observation unit is electrically connected to the signal processing unit. The observation unit is made in the form of analog-to-digital converters and a display. Seven linear scales are located vertically at the same level on the display to display information about the corresponding measured parameter. Equally spaced along each linear scale are LEDs. The LEDs are electrically connected to the power supply and to a corresponding analog-to-digital converter.

The disadvantage of such a device for monitoring the drilling process is the lack of the possibility of remote monitoring of the parameters of the drilling process, operational transfer of the device to another drilling rig, creating a data archive and analyzing the drilling process in time, and transmitting data via external communication channels.

A known system for monitoring the drilling process contains a group of object computers installed on the drilling rigs, connected through communication channels with a central computer, into which a network router and a group of object routers are additionally introduced, the first inputs and outputs of each of which are connected to the corresponding object block, the second inputs - the outputs of the object routers through communication channels and the network router are connected to the central computer, the downhole tool connected to the transmitting device, which, in turn, is connected to parts of the casing or drill string, separated by an electric divider, at least one receiving antenna connected to a receiving device, which includes a GPS receiver built into a downhole tool that can receive signals from at least three satellites (RU, application No. 2006133698, Е21В 47/00, Publ. 03/27/2008). The object router contains a module for creating a virtual private communication network that performs communication through a communication channel with a network router, as well as authentication of network users. The network router contains a module for creating a virtual private communication network that performs communication through communication channels with object routers and authenticates network users, as well as a firewall module for protecting the monitoring station from unauthorized access from the communication channel. An entity router can contain more than one link controller that couples the object router to associated links. A network router can contain more than one link controller that interfaces the network router to links.

The disadvantage of such a monitoring system for the drilling process is the impossibility of real-time determination of the complex of controlled technological parameters necessary and sufficient to assess the state of technological processes during well drilling.

A known system of information support for geological support for drilling complex wells, including a block for loading data on well surfaces, an information input block, an information comparison block, a control unit for loaded information, an indication unit, a block for loading static information on a well, a block for loading well logging studies, an interaction block with data sources, surface data storage unit, drilling target data storage unit, well logging data storage unit, telemetry operational data storage unit, internal settings data storage, administration unit, emergency forecasting unit, data visualization unit, telemetry collection unit data from drilling rigs, and the block for loading static information on the well is connected by one-way connection to the information input block, the block for downloading data on the well surfaces is connected by one-way connection to the information input block, the block loading of well logging studies by one-way communication is connected to the information input unit, the display unit is connected by two-way connections to the information input unit, the data source interaction unit, the administration unit, the data visualization unit, the emergency prediction unit, the data source interaction unit by the two-way connections is connected to surface data storage unit, drilling target data storage unit, well logging data storage unit, telemetry operational data storage unit, the data source interaction unit is connected by one-way communication with the information comparison unit, the information comparison unit is connected by one-way communication with the loaded information control unit, the unit for controlling the downloaded information is connected by one-way communication with the data visualization unit, the internal data storage for settings is connected by two-way communication with the administration unit, the unit for collecting a telemeter data from drilling rigs by one-way communication is connected to the unit for storing operational telemetry data (RU, patent No. 149833, G06F 17/40, E21B 47/26, Publ. 01/20/2015, Bul. No. 2).

The disadvantage of such a system of information support for geological support for drilling complex wells should be attributed to its complexity, which consists in a large number of blocks interconnected by various connections, which limits the possibility of its operational transfer from one drilling rig to another, thereby limiting its mobility.

The closest to the claimed system is a mobile station for monitoring drilling parameters, containing sensors for measuring the weight of a drilling tool, working fluid pressure, drilling fluid flow rate, analog-to-digital converters (ADC), a power supply, a processor with a control program, made with the ability to create a data archive , coming from sensors, and transfer of the specified data to dispatch centers and to removable media, memory unit, timer, USB port, port for connecting external communication channels, travel block position sensor, communication module, with a processor with a control program, memory unit, timer , USB ports, connections for external communication channels and ADCs are compactly placed in one data acquisition device that provides collection, processing, storage, updating and transmission of data at specified intervals from the specified sensors, giving an alarm according to a specified algorithm of the control program via USB ports or external communication channels, and the memory block is made non-volatile (RU, patent No. 2380533, E21B 44/00, Publ. 27.01.2010, Bul. No. 3).

The disadvantage of such a mobile station for monitoring drilling parameters is the lack of a number of controlled parameters, which leads to a lack of information and the impossibility of qualitatively assessing the state of technological processes during drilling, and, consequently, to determine the direction and intensity of subsequent control actions.

The disadvantage of such a mobile station should also include the fact that, despite the possibility of using surface sensors in an overhead method to measure the weight of a drilling tool, pressure of a working fluid, flow rate of drilling mud, position of a traveling block without additional inserts and changes in the existing design of a drilling rig, the installation of such a mobile stations on each drilling rig for monitoring the drilling parameters and its subsequent dismantling after the measurements are made are associated with the need to carry out a number of additional operations that require both time expenditures and some additional efforts.

The disadvantage of this mobile station is also the impossibility of obtaining information about the geographic coordinates of the points of the wells in which the drilling parameters were measured, which does not allow with sufficient accuracy and with minimal effort to build a three-dimensional model of the ore body. Otherwise, for these purposes, the involvement of a geological and technical service is required.

The invention is based on a technical problem, which consists in creating a monitoring system for technological parameters of the drilling process based on a self-propelled drilling rig, characterized by the ability to determine in real time a set of monitored parameters necessary and sufficient to assess the state of the technological process while drilling wells, the ability to record, display, accounting, storage and transmission of the current parameters of the drilling process by means of communication for subsequent control of the drilling process, as well as the ability to obtain accurate information about the geographic coordinates of the points of the wells in which the drilling parameters were measured.

At the same time, the technical result is the ability to quickly assess the state of the technological process while drilling wells.

Achievement of the above technical result is ensured by the fact that in the monitoring system of technological parameters of the drilling process based on a self-propelled drilling rig, including sensors for measuring parameters and a data collection device, the data collection device contains a data collection module, a data recording and storage module and a data transmission module, while the data collection module contains one controller or two interconnected CAN bus controllers, and an analog-to-digital converter, is equipped with a CAN bus connection port for reading the operating parameters of the chassis internal combustion engine from the electronic engine control unit, the data collection module is configured to calculate the monitored parameters and two-way communication is connected to the display for displaying the monitored parameters in real time, to the data collection module through the corresponding ports are connected the speed sensor of the hydraulic motor of the rotator, the pressure sensor of the working fluid of the pressure line guide rotator rotor, rpm sensors of the tackle system crown block, hydraulic pressure sensors of the hydraulic cylinder for lowering / lifting of the rotator, hydraulic fluid level sensor, hydraulic fluid temperature sensor, data acquisition module is connected by a two-way CAN communication line with the data recording and storage module , the data recording and storage module is two-way connected to the data transmission module equipped with a port for connecting external communication channels.

The data acquisition device may further comprise a satellite radio navigation system (GPS) module, wherein the satellite radio navigation system (GPS) module is connected to the data recording and storage module.

The data recording and storage module can be made non-volatile.

A touchscreen display can be used as a display.

The display can be equipped with a data input device.

This allows you to quickly assess the state of the technological process while drilling wells.

Thirdly, the data collection module provides the transfer of processed information about the monitored parameters of the drilling process to the data recording and storage module. At the same time, it is possible to read the operating parameters of the chassis internal combustion engine from the electronic engine control unit due to the presence of a CAN bus connection port in the data acquisition module.

Due to the connection of the data acquisition module with the display, the monitored parameters are displayed in real time.

At the same time, the use of two-way connections between the corresponding modules ensures the exchange of information between them.

The presence of a satellite radio navigation system (GPS) module in the data collection device provides the ability to obtain accurate information about the geographic coordinates of the points of the wells in which the drilling parameters were measured in order to fulfill the design task, the conditions of which are the most accurate observance of the specified geographic coordinates of the well grid. This makes it possible to build a three-dimensional model of the ore body with sufficient accuracy and with minimal effort. Otherwise, for these purposes, the involvement of a geological and technical service is required.

The connection of the satellite radio navigation system (GPS) module with the data recording and storage module provides the recording and storage of information on the geographic coordinates of the borehole points in which the drilling parameters were measured.

The implementation of the module for recording and storing data non-volatile provides the ability to save information for a specified period of time in the event of possible power failures.

The use of a touch screen or a display with a data input device allows both displaying the monitored parameters of the drilling process in real time, and entering data such as, for example, the number of the well, the crew number, the type of drilling, as well as the parameters necessary for calculating the monitored parameters of the drilling process.

The essence of the invention is illustrated by the following drawings. FIG. 1 shows a self-propelled drilling rig with a system for monitoring technological parameters of the drilling process, general view; in fig. 2 shows a block diagram of a system for monitoring technological parameters of the drilling process.

The system for monitoring technological parameters of the drilling process is installed on a self-propelled drilling rig.

The system for monitoring technological parameters of the drilling process based on a self-propelled drilling rig includes a data collection device 12 and sensors for measuring parameters, which are used as a sensor 13 for the number of revolutions of the rotator hydraulic motor, sensor 14 for the pressure of the working fluid of the pressure line of the hydraulic motor of the rotator, sensors 15 for the number of revolutions of the crown block. systems, pressure sensors 16 of the working fluid of the hydraulic cylinder lowering / raising the rotator, the sensor 17 of the level of the working fluid in the hydraulic system, the sensor 18 of the temperature of the working fluid in the hydraulic system.

The data collection device 12 contains a data collection module 19, a data recording and storage module 20 and a data transmission module 21.

The data acquisition module 19 contains one controller or two interconnected CAN bus controllers, and an analog-to-digital converter (not shown).

The data acquisition module 19 is equipped with a CAN bus connection port 22 for reading the operating parameters of the chassis internal combustion engine from the electronic engine control unit. The CAN bus is, in particular, the J1939 CAN bus.

The data collection module 19 is configured to calculate the monitored parameters and is two-way connected to the display 23 to display the monitored parameters in real time.

As a display 23, a touchscreen display can be used, which allows both displaying the monitored parameters of the drilling process in real time, and entering data such as, for example, the number of the well, the number of the crew, the type of drilling, as well as the parameters necessary for calculating the monitored parameters of the drilling process. ... It is also possible to use a display with a data input device (not shown), which also allows both displaying the monitored parameters of the drilling process in real time, and entering data such as, for example, the number of the well, the crew number, the type of drilling, as well as the parameters required for calculation of the controlled parameters of the drilling process.

The data recording and storage module 20 is two-way connected to the data transmission module 21 equipped with a port for connecting external communication channels 24.

The data collection device 12 additionally contains a satellite radio navigation system (GPS) module 25. In this case, the satellite radio navigation system (GPS) module 25 is connected to the data recording and storage module 20.

The data recording and storage module 20 is non-volatile.

To power the system for monitoring the technological parameters of the drilling process, the power supply system of the self-propelled drilling rig was used.

The system for monitoring technological parameters of the drilling process based on a self-propelled drilling rig works as follows.

According to the approved drilling plan, the crew arrives at the drilling site as part of a self-propelled drilling rig with a system for monitoring technological parameters of the drilling process installed on it. The drilling rig is being deployed from the stowed position to the working one. Preparatory operations are carried out before the actual drilling process, including the initial parameters, such as the number of the well, the number of the crew, the type of drilling. Further, the well is drilled directly with monitoring of the technological parameters of the drilling process.

Due to the presence of a system for monitoring technological parameters of the drilling process on a self-propelled drilling rig, the need to install such a system when drilling each well to control the parameters of the drilling process and its subsequent dismantling after the measurements is eliminated. This eliminates the implementation of a number of additional operations that require both time costs and some additional efforts, and makes it possible to quickly assess the state of technological processes when drilling wells according to a set of controlled parameters determined in real time, which are necessary and sufficient for assessing the states of technological processes during drilling. wells.

The parameters are measured by the following sensors installed on the drilling rig and connected to the data collection module 19 of the data collection device 12 through the corresponding ports: sensor 13 of the number of revolutions of the hydraulic motor of the rotator, sensor 14 of the pressure of the working fluid of the pressure line of the hydraulic motor of the rotator, sensors 15 of the number of revolutions of the crown block of the traveling system , pressure sensors 16 of the working fluid of the hydraulic cylinder lowering / raising the rotator, the sensor 17 of the level of the working fluid in the hydraulic system, the sensor 18 of the temperature of the working fluid in the hydraulic system.

The following parameters of the drilling process are measured:

- the number of revolutions of the hydraulic motor of the rotator;

- pressure of the working fluid of the rotator;

- the number of revolutions of the crown block of the traveling system;

- pressure of the working fluid in the piston and rod cavity of the hydraulic cylinder of the lowering / lifting of the rotator;

- the level of the working fluid in the hydraulic system;

- the temperature of the working fluid during the operation of the drilling rig.

To determine the number of revolutions of the rotator hydraulic motor, an inductive sensor 13 is used, which is mounted in the housing of the flange of the hydraulic motor attachment to the rotator housing. A toothed washer is installed on the hydraulic motor shaft. The sensor 13 reads the teeth at the moment of rotation of the hydraulic motor shaft due to the change in the amplitude of the oscillation of the magnetic waves when the protruding part of the tooth head of the toothed washer is in the active zone of the sensor 13.

An analog sensor 14 is used to measure the pressure of the working fluid of the rotator. Pressure measuring range from 0 to 400 bar. The cylindrical body of the sensor allows its installation in any accessible place of the pipeline connection.

To determine the number of revolutions of the crown block of the traveling system, two inductive sensors 15 of the number of revolutions are used, installed on the crown block of the drilling rig. They are located relative to each other at an angle of 45 degrees. The crown block pulley has protruding stiffeners in its design. When it rotates, the ribs fall into the active zone of the sensors. The time difference between the two sensors is used to determine the speed of the pulley.

To measure the pressure of the working fluid in the piston and rod cavity of the hydraulic cylinder lowering / lifting the rotator, two analog-type working fluid pressure sensors 16 are used, one of which is built into the piston cavity of the hydraulic cylinder lowering / raising the rotator, the other into the rod cavity. Depending on the movement of the hydraulic cylinder rod up or down, the working pressure is determined by the corresponding sensor. Pressure measurement range from 0-400 bar.

The level of the working fluid in the hydraulic system is determined by a discrete type float sensor 17. It is installed in the hydraulic oil tank. Sensor 17 provides switching of the reed switch contacts when the liquid level is below or equal to the monitored level.

The temperature of the working fluid during the operation of the drilling rig is monitored by an analog type oil temperature sensor 18. It provides accurate temperature measurement and signal transmission to the data input module. Sensor 18 is mounted on the side wall of the hydraulic oil tank.

Due to the presence of the port 22 for connecting the CAN bus for reading the operating parameters of the internal combustion engine of the chassis from the electronic engine control unit, the following parameters are monitored:

- the speed of the chassis internal combustion engine,

- the temperature of the cooling liquid of the chassis internal combustion engine,

- oil pressure of the chassis internal combustion engine,

- battery voltage,

- fuel level in the tank.

In this case, the CAN bus is used, in particular, the CAN bus J1939.

Analog, frequency and discrete signals from the sensors enter the data collection module 19, which contains one controller or two interconnected CAN bus controllers, and an analog-to-digital converter.

The processing of the incoming signals from the sensors is carried out by an analog-to-digital converter, which receives the indicated analog, frequency and discrete signals from the sensors and converts them into digital form.

Due to the presence in the data acquisition module 19 of one or two controllers interconnected by the CAN bus, the monitored parameters of the drilling process are calculated according to the built-in mathematical algorithm, using the parameters measured by the sensors, as well as entered from the touch screen.

In this case, the following controlled parameters of the drilling process are calculated:

- the number of revolutions of the spindle of the rotator,

- torque of the rotator spindle,

- the effort to feed the drill to the bottom of the well,

- effort on the hook when lifting the drill,

- the feed rate of the drill,

- well drilling depth.

The number of revolutions of the spindle of the rotator is determined by the formula:

V = V _g ⋅i _p , rpm

where V _g is the speed of the output shaft of the hydraulic motor, rpm;

i _p is the gear ratio of the mechanical transmission of the rotator (parameter set manually from the touch display, depending on the installed mechanical transmission on the rotator).

The torque of the rotator spindle is determined by the formula:

where q _g is the working volume of the hydraulic motor, cm ³ / rev (parameter set manually from the touch screen depending on the set volume of the hydraulic motor);

Δ _p - pressure drop, kgf / cm ³ (parameter set manually from the touch screen depending on the set pressure of the hydraulic system);

η - hydromechanical efficiency of the hydraulic motor (constant value corresponding to the installed hydraulic motor and set manually from the touch screen).

The effort to feed the drill to the bottom of the well is determined by the formula:

where Δ _p is the pressure drop, kgf / cm ³ (parameter set manually from the touch screen depending on the set pressure of the hydraulic system);

d ² - outer diameter of the hydraulic cylinder piston, cm (parameter set manually from the touch screen);

π - constant value set manually from the touch screen.

The effort on the hook when lifting the drill is determined by the formula:

where Δ _p is the pressure drop, kgf / cm ³ (parameter set manually from the touch screen depending on the set pressure of the hydraulic system);

- наружный диаметр штоковой полости гидроцилиндра, см (параметр, задаваемый вручную с сенсорного дисплея);

- outer diameter of the rod cavity of the hydraulic cylinder, cm (parameter set manually from the touch screen);

- внутренний диаметр штоковой полости гидроцилиндра, см (параметр, задаваемый вручную с сенсорного дисплея).

- inner diameter of the rod cavity of the hydraulic cylinder, cm (parameter set manually from the touch screen).

The feed rate of the drill is determined by the formula:

- перемещение каретки вращателя при повороте крон-блока на угол 45°, см (параметр, задаваемый вручную с сенсорного дисплея);Where

- movement of the rotator carriage when the crown block is rotated at an angle of 45 °, cm (parameter set manually from the touch screen);

Δt is the time interval between the actuation of the crown block position sensors, sec.

каждый раз при срабатывании индуктивного датчика в процессе бурения.Drilling depth is calculated by adding (adding) a given value

every time an inductive sensor is triggered while drilling.

Further, the processed information about the monitored parameters of the drilling process is transmitted via a two-way CAN communication line from the data collection module 19 to the data recording and storage module 20 for its registration, encryption and storage. The implementation of the module for recording and storing data 20 non-volatile provides the ability to save information for a specified period of time in the event of possible power failures.

Thanks to the use of a two-way CAN communication line, on the one hand, the processed information about the monitored parameters of the drilling process is transmitted from the data acquisition module 19 to the data recording and storage module 20 for its registration, encryption and storage, and, on the other hand, the data recording and storage module 20 serves as a link between the data transmission module 21, equipped with a port for connecting external communication channels 24, and the data collection module 19. This provides the ability to remotely configure and set the measurement limits of sensors in the event of replacement or calibration.

The information about the monitored parameters of the drilling process processed by the data collection module 19 is also displayed in real time on the display 23, due to its connection with the data collection module 19 by two-way communication. At the same time, the use of two-way communication and the use of a touch screen or a display with a data input device provides both the ability to display the monitored parameters of the drilling process in real time and the ability to enter the necessary data into the data collection module 19.

The encrypted data on the monitored parameters of the drilling process from the data recording and storage module 20 are transmitted to the data transmission module 21, equipped with a port for connecting external communication channels 24, such as the Internet, GSM, radio lines, satellite communications, cable communication lines and their combinations. Further, the specified data is transmitted to the server, which has access to executives, heads of drilling sites and other specialists involved in drilling. At the same time, thanks to the use of two-way communication, it is possible to remotely configure and set the measurement limits of sensors in the event of their replacement or calibration.

A prerequisite for the fulfillment of the design assignment, in particular, is the most accurate observance of the specified geographic coordinates of the well grid. The possibility of obtaining such information about the geographic coordinates of the borehole points in which the drilling parameters were measured is provided by the presence of a satellite radio navigation system (GPS) 25 module in the data collection device 12. This makes it possible to construct a three-dimensional model of the ore body with sufficient accuracy and with minimal effort. In this case, for these purposes, the involvement of a geological and technical service is not required. At the same time, the connection of the satellite radio navigation system (GPS) module 25 with the data recording and storage module 20 provides the recording and storage of information on the geographic coordinates of the borehole points in which the drilling parameters were measured.

Thus, the system for monitoring technological parameters of the drilling process based on a self-propelled drilling rig makes it possible to quickly assess the state of technological processes when drilling wells according to a set of controlled parameters determined in real time, which are necessary and sufficient to assess the states of technological processes when drilling wells and for subsequent process control. drilling.
