Description

Technical Field

[0001] This invention belongs to the field of oil drilling and logging technology, and in particular relates to an integrated drilling surface acquisition and downlink control system panel. Background Technology

[0002] With the rise of drilling while drilling and logging technologies, various logging instruments have emerged, and surface acquisition systems and downlink control systems have also become diverse. However, as oil extraction becomes more difficult and cost control becomes more stringent, relative investment is decreasing. Consequently, the mainstream trend is towards integrated systems with enhanced functionality, increased equipment integration, and more comprehensive equipment functions. Currently, drilling acquisition and downlink control panels on the market can be roughly divided into the following two categories:

[0003] Independent data acquisition panel:

[0004] These types of panels can only collect data from each sensor individually and cannot transmit data down to control the instrument status. They cannot achieve simultaneous measurement and control. When accidents occur during drilling, errors cannot be corrected in time, delaying the drilling schedule, increasing time, and wasting manpower, material resources, and financial resources.

[0005] Well platform data acquisition control panel:

[0006] While such panels can display the collected data in real time and control the instruments to follow the correct trajectory to complete drilling, they have high overall requirements. They require explosion-proof certification for the entire acquisition and control system, have high temperature requirements, increase manufacturing costs, and are not conducive to profit control. Summary of the Invention

[0007] To address the above issues, this invention proposes an integrated drilling surface data acquisition and downlink control system panel. This panel comprises several parts, including a sensor acquisition unit, a downlink control module, and a network data exchange terminal. This effectively solves the shortcomings of independent acquisition panels, which cannot transmit data to control instruments, and also addresses the high cost of wellhead acquisition control panels. This panel can independently acquire data from each sensor, simultaneously observe the status of each sensor, expand the number of sensors, and provide real-time control of downhole instruments. This prevents accidents during drilling, promptly corrects drilling errors, and adjusts instrument movement trajectories in real time, saving costs. It achieves both real-time data acquisition and real-time control within a single system.

[0008] The specific technical solution is as follows:

[0009] An integrated drilling surface data acquisition and downlink control system panel mainly includes a protective housing, a panel, and internal module units. The protective housing is equipped with a pressure relief valve. The internal module units mainly include a small computer, a digital signal processing module, a safety barrier module, a downlink module, a downlink interface module, a display module, and a power supply module. The support column supports the base plate fixing plate in the base plate fixing area.

[0010] The safety barrier module, power supply module, digital signal processing module, and minicomputer are fixed in the base plate fixing area;

[0011] The digital signal processing module collects and processes the digital and analog signals sent by the safety barrier module, and sends them to the minicomputer for data forwarding. The minicomputer then sends the signals collected and processed by the digital signal processing module to the host computer through the network data exchange terminal.

[0012] The panel mainly includes a downlink status display screen, a downlink output interface, a downlink status indicator light, a downlink computer interface, a downlink module, an independent power supply switch for the downlink section, a first-generation driver display computer connection terminal, a ground analog decoding interface, analog sensor interface 1, analog sensor interface 2, digital sensor interface 1, digital sensor interface 2, an integrated interface, an air inlet / outlet 1, an air inlet / outlet 2, a power supply interface, a main power switch, a computer connection terminal, a network data exchange terminal, and a panel lifting handle.

[0013] The downlink status display screen, downlink output interface, downlink status indicator light, downlink computer interface, and independent power supply switch for the downlink section are located in the downlink control unit area. The integrated interface, analog sensor interface 1, analog sensor interface 2, digital sensor interface 1, and digital sensor interface 2 are located in the sensor acquisition unit area. The power supply interface and main power switch are located in the power input and control unit area. The computer connection terminal and network data exchange terminal are located in the network exchange unit area.

[0014] The integrated drilling surface data acquisition and downlink control system panel can simultaneously connect to four 4-20mA 2-wire sensors (Sensor 1, 2, 3, 4, 4, 5, and 6) via analog hubs 1 and 2. It can also connect to the encoder wheel sensor, scale switch sensor, and ground speed sensor via digital hub 1, and to pump pulse sensor 1, 2, 3, and 4 via digital hub 2. Furthermore, it supports direct connection to devices using a single cable for data transmission, including direct connections to the host computer, data transmitter, negative pulse generator, and four 4-20mA 2-wire sensors. The connection between the line sensor 3, the encoder wheel sensor, the first-generation driller's display, and the second-generation driller's display is as follows.

[0015] The integrated drilling surface data acquisition and downlink control system panel acquires data from 4-20mA 2-wire sensor 1, 4-20mA 2-wire sensor 2, 4-20mA 2-wire sensor 3, 4-20mA 2-wire sensor 4, 4-20mA 3-wire sensor 1, 4-20mA 2-wire sensor 5, and 4-20mA 2-wire sensor 6 via a safety barrier module. After digital-to-analog and analog-to-digital conversion, the data undergoes preprocessing by a digital signal processing module. The processed data is then formatted by a small computer and sent to the host computer via a network data exchange terminal for database entry. Downlink data is transmitted via the host computer's serial port to the downlink control module. The downlink control module converts the data level and transmits it through the downlink interface module to a negative pulse generator, which then sends it in pulse form to the remote actuator for corresponding actions. Beneficial effects

[0018] 3. All power supply interfaces, input / output interfaces, heat dissipation and ventilation systems, displays, and network switches are integrated in the core area of ​​the device, making it easy to operate;

[0019] 4. The equipment's pressure relief valve design balances internal and external pressure, allowing for easy opening of the equipment and preventing situations where the equipment cannot be opened due to internal and external pressure differences when used in high-altitude environments.
