Description

Technical Field

[0001] This invention belongs to the technical field of drilling site monitoring systems, specifically relating to a drilling parameter monitoring system for 10,000-meter drilling rigs, and also to a method for monitoring drilling parameters for 10,000-meter drilling rigs. Background Technology

[0002] As oil exploration and development enters the 10,000-meter era, conducting geological and engineering scientific research on ultra-deep formations at depths of 10,000 meters, and pushing the limits of deep-earth drilling through technological breakthroughs, is a major technological challenge for the global oil industry. Depth brings numerous difficulties; ultra-deep well drilling is the area with the most bottlenecks and greatest challenges in oil and gas engineering technology. The maximum load on the hook of a 10,000-meter drilling rig far exceeds the maximum load of commonly used weight gauges, the calibrated pull force on the tong torque sensor also exceeds conventional values, the number of mud pits increases exponentially, and well conditions become more complex. Conventional drilling parameter monitoring systems cannot meet the on-site construction needs of 10,000-meter drilling rigs, such as full-range data acquisition, high response rates, and integrated information display. A search yielded the following patent documents: Patent "A Data Monitoring System and Method Based on Drilling Parameter Instrument" (Publication No.: CN103615232B, Publication Date: 2014-03-05) discloses a data access method for a drilling parameter data digitization disc recorder. This method only addresses the limitation that the drilling parameter data digitization disc recorder, being a mechanical drawing device, cannot query historical data, making it insufficient to meet the practical needs of integrated information display in 10,000-meter drilling rig operations. Patent "A Drilling Engineering Parameter Monitoring System" (Publication No.: CN105298466A, Publication Date: 2016-02-03) discloses a drilling engineering parameter monitoring method, which can achieve collaborative monitoring of drilling engineering parameters. However, this method highly relies on external reference data related to engineering parameters and is not suitable for the actual situation of 10,000-meter drilling rigs lacking relevant reference construction engineering parameters. The patent “A Drilling Parameter Monitoring System for Drilling Sites” (Publication No.: CN106059859A, Publication Date: 2016-10-26) discloses a method for monitoring drilling parameters based on wireless means, but this method is not suitable for the on-site construction requirements of high response rate for parameter acquisition in drilling operations at depths of 10,000 meters. Summary of the Invention

[0009] The hook suspension weight sensor, clamp torque sensor, and riser pressure sensor are connected to a pressure transducer box via pressure pipelines. The pressure transducer box is connected to the analog signal acquisition module of the first data acquisition box via signal cables. The well depth sensor is connected to the depth signal acquisition module of the first data acquisition box. Several pump speed sensors are connected to the pulse signal acquisition module of the second data acquisition box. The mud outlet discharge sensor and several mud tank level sensors are connected to the signal acquisition module of the second data acquisition box.

[0010] Another technical solution adopted in this invention is a method for monitoring drilling parameters of a 10,000-meter drilling rig, which specifically includes the following steps: S1: Configure the functional module ID addresses of the first and second data acquisition boxes; configure the IP addresses of the first wireless node, the second wireless node, the electrical control PLC, and the OPC server. S2: Set the monitoring parameter sampling period, set the display drilling parameters, parameter display range, subdivision scale value, and alarm threshold in the OPC server; and test and verify the button function, parameter correction function, and selection function, and set the function parameters. S3: The first and second data acquisition boxes collect data from each sensor and provide the data source to the OPC server via CAN communication and network communication. S4: The parameters are displayed in a unified manner on the OPC server, PLC, and back-end server. Alarms are triggered or information is pushed to relevant personnel for abnormal data.

[0011] Another feature of the technical solution of this invention is that: S1 specifically refers to: After the hardware connection is completed, based on CAN communication technology, the communication control protocol of the communication control module in the first and second data acquisition boxes is designed, mainly including data frame structure, instruction frame structure, CAN node object ID encoding rules, data transmission baud rate, and data query method; according to the CAN node object ID encoding rules, the ID address of each functional module is uniformly encoded, and the ID address of each functional module is configured. Set up a local area network (LAN) environment. Data communication uses the TCP / IP network protocol. Design the IP addresses for the OPC server, the first data acquisition box, the electrical control PLC, the first wireless node, the backend server, and the second wireless node to ensure that the IP addresses of the LAN objects are all in the same IP segment. Configure and verify the designed IP addresses in each LAN object system.

[0012] S2 specifically refers to: According to the drilling requirements of the 10,000-meter drilling rig, the sampling period for the hook suspension weight parameter and riser pressure parameter is designed to be 120ms, and the sampling period for other parameters is set to meet the requirements of on-site use; the sampling period designed according to the monitoring parameters of the drilling parameter monitoring system is set accordingly in the OPC server acquisition software. The drilling parameter monitoring system for the 10,000-meter drilling rig needs to monitor the direct and derived parameters. Direct parameters include: hook weight, standpipe pressure, tong torque, mud return volume, pump stroke, rotary table torque and speed, top drive torque and speed, hook height, and mud level in the mud tank. Derived parameters include: drilling pressure, pump stroke count, mud outlet flow rate, rope work, well depth, drill bit position, drilling time, and hook speed. In the OPC server software, the display range, subdivision scale value, and alarm threshold of each direct and derived parameter should be set individually.

[0014] S4 specifically refers to: The OPC server, electrical control PLC, and back-end server are all equipped with a real-time drilling engineering parameter, alarm prompts, and integrated information display method; After the sensors in the first and second sensor packages collect data, the data is transmitted to the first and second data acquisition boxes, respectively. The OPC server reads the rotary table torque and speed, and top drive torque and speed signal data of the 10,000-meter drilling rig and transmits them to the electrical control PLC. The electrical control PLC reads the drilling monitoring parameters of the 10,000-meter drilling rig and displays them on the touch screen, which is installed in the driller's cabin. At the same time, the control commands generated by the instrument interface operation on the touch screen are read by the OPC server of the 10,000-meter drilling rig drilling parameter monitoring system. The monitoring parameters read by the OPC server are transmitted back to the data interface conversion module of the first data acquisition box via the bus. The data is then transmitted to the first wireless node via the interface conversion module.

The backend server synchronously displays the drilling monitoring parameters during the drilling process of the 10,000-meter drilling rig. The integrated display of drilling engineering parameter information is presented in numerical, curve, scale, bar chart, and actual working condition formats. When the monitored parameters exceed the preset alarm threshold, an alarm is triggered by voice broadcast, pop-up prompts, and color-coded display values. The drilling parameter monitoring of the 10,000-meter drilling rig is completed.

[0015] The beneficial effects of this invention are: 1. The drilling parameter monitoring system for 10,000-meter drilling rigs of this invention, with its matching sensor package, effectively solves the problem that the maximum load of the hook suspension in 10,000-meter drilling operations far exceeds the maximum load of commonly used weight indicators, increasing the measurement range by 53%; it also effectively solves the problem that the calibrated tension of the tong torque sensor on the tongs also exceeds the conventional value in measurement, increasing the measurement range by 53%. 2.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] This invention relates to a drilling parameter monitoring system for 10,000-meter drilling rigs, such as... Figure 1 As shown, it includes a first sensor pack and a second sensor pack. The first sensor pack is connected to a first data acquisition box via a first bus, and the second sensor pack is connected to a second data acquisition box via a second bus. The first data acquisition box and the second data acquisition box are connected via a bus. The first sensor package includes a hook suspension weight sensor, a tong torque sensor, a riser pressure sensor, and a well depth sensor; the second sensor package includes several pump speed sensors, mud outlet discharge sensors, and several mud tank level sensors. The hook suspension weight sensor converts the tension of the dead rope into a pressure signal by squeezing the liquid through a diaphragm, which is then transmitted to the weight indicator and recorder. To adapt to drilling rigs operating at 10,000 meters, a wide-range hook suspension weight sensor is adopted. The diaphragm material and manufacturing process of the sensor have been improved, replacing nitrile rubber with polyurethane-reinforced fabric, increasing the diaphragm's lifespan and the sensor's measurement range, ensuring the maximum load measurement requirements of the hook suspension weight on drilling rigs operating at 10,000 meters are met.

[0019] The tong torque sensor is a custom-designed sensor. To adapt to 10,000-meter drilling rigs, the conventional tong torque sensor has its cylinder length increased and its material changed to expand its measurement range. Specifically, the cylinder length was increased from 128mm to 138mm, the piston rod from 192mm to 202mm, and the material was changed from 45# steel to 17-4 precipitated stainless steel, thus ensuring the shackle calibration tension measurement requirements of the 10,000-meter drilling rig. The mud tank level sensor uses explosion-proof ultrasonic level sensors. The specific number is determined by the number of drilling fluid mud tanks at the drilling site, ensuring the drilling fluid mud tank level measurement requirements of the 10,000-meter drilling rig. It is equipped with a fixed bracket for easy assembly and disassembly, meeting the multi-mud tank level measurement needs of 10,000-meter drilling rigs with large mud volume requirements. The sensors in the first and second sensor packages are installed at the corresponding measurement positions on the 10,000-meter drilling rig.

[0020] General data acquisition boxes, such as Figure 2As shown, the system includes a power supply module, a pulse signal acquisition module, an analog signal acquisition module, a depth signal acquisition module, a switch signal output module, a communication control module, an interface conversion module, and a bus. It adopts a modular design, allowing users to select the appropriate functional module based on actual data acquisition needs for plug-and-play functionality. The pulse signal acquisition module integrates one pulse signal acquisition channel and one raw pulse signal output channel; the analog signal acquisition module integrates current and voltage signal acquisition functions with an adjustable acquisition range; the depth signal acquisition module integrates relative and absolute depth signal acquisition functions; the communication control module integrates a CAN communication transceiver controller and a CAN communication isolation chip, and is used in parallel with the pulse signal acquisition module, analog signal acquisition module, depth signal acquisition module, and switch signal output module via a CAN bus; one input of the interface conversion module is connected to the communication control module via a CAN bus, and the other output is compatible with CAN and RS. 485, TCP / IP, and fiber optic communication facilitate communication with OPC servers, wireless nodes, and data acquisition boxes; it reserves the function of providing raw data signals, such as riser pressure signals required by drilling parameter monitoring systems and logging engineering systems. A riser pressure signal processing module can be added to the analog signal acquisition module, which, after isolation and interference suppression, can output multiple raw signals as needed; the signal processing module input is compatible with both current and voltage input signals, and the output can be either current or voltage signals; all raw signals are reserved in socket form and come with matching quick-connect plugs. Specifically, the system of the present invention, such as Figure 3 As shown, the first data acquisition box includes a power module, which is connected to an analog signal acquisition module, a depth signal acquisition module, and a switch signal output module. The analog signal acquisition module acquires signals from the hook suspension sensor, clamp torque sensor, and riser pressure sensor. The depth signal acquisition module acquires well depth sensor information. The switch signal output module generates signals to control an alarm horn for alarm prompts such as parameter exceeding limits. The analog signal acquisition module, depth signal acquisition module, and switch signal output module are connected to a communication control module via a sixth bus. The communication control module is connected to an interface conversion module via a seventh bus. The interface conversion module integrates a switch, a wireless module, and a fiber optic module. The wireless module connects to the wireless node and controls data transmission and reception, while the fiber optic module controls data transmission and reception on the fiber optic bus. The interface conversion module is connected to the OPC server and the first wireless node via a bus. The analog signal acquisition module includes a riser pressure signal processing module, reserving raw signals for the electrical control PLC and logging.

[0021] like Figure 3As shown, the second data acquisition box includes a power supply module, which is connected to a pulse signal acquisition module and an analog signal acquisition module. The pulse signal acquisition module acquires pulse signals from the explosion-proof pump pulse sensor, and the analog signal acquisition module acquires information from the mud outlet discharge sensor and multiple mud tank level sensors. The pulse signal acquisition module and the analog signal acquisition module are respectively connected to an interface conversion module via an eighth bus. The pulse signal acquisition module and the analog signal acquisition module are also connected to the communication control module of the first data acquisition box via a ninth bus, meaning that the first data acquisition box and the second data acquisition box share a single communication control module. The interface conversion module is connected to the OPC server via a bus.

[0022] The first data acquisition box is installed in the left side room, and the second data acquisition box is installed in an appropriate location in the drilling platform mud tank area.

[0023] The first data acquisition box is connected to the OPC server via the third bus, and the second data acquisition box is connected to the OPC server via the fourth bus. The OPC server is installed in the drilling platform's electrical control room, integrating drilling parameter processing, visualization, and data communication. It connects to the electrical control PLC via the fifth bus to directly read the rotary table torque and speed, and top drive torque and speed signal data associated with the 10,000-meter drilling rig. The OPC server shares the monitoring parameters from the 10,000-meter drilling rig's drilling parameter monitoring system to the electrical control PLC via the bus. The electrical control PLC is a third-party PLC, including PLC1 and PLC2. Specifically, the monitoring parameters from the 10,000-meter drilling rig's drilling parameter monitoring system are shared to third-party PLC1 via the bus. Third-party PLC1 communicates with third-party PLC2. The system reads and displays the drilling monitoring parameters of the 10,000-meter drilling rig from the data block on its touchscreen, which is installed in the driller's cabin. This touchscreen intelligently assists the driller's operations, improving drilling efficiency. Simultaneously, control commands generated by the instrument interface on the touchscreen are written into the PLC2 data block and read by the 10,000-meter drilling rig parameter monitoring system. The OPC server shares the monitoring parameters of the 10,000-meter drilling rig parameter monitoring system via the fifth bus to the conversion interface module of the first data acquisition box. The conversion interface module is connected to the first wireless node, which acts as the transmitting end for the 10,000-meter drilling rig parameter monitoring system. The monitoring system also includes a backend server, installed in the drilling engineer's office. The backend server is connected to a second wireless node, which acts as the receiving end for the 10,000-meter drilling rig parameter monitoring system. The backend server synchronously displays the drilling monitoring parameters during the 10,000-meter drilling process to the drilling team technicians and has storage, parameter review, and printing functions.

[0024] The drilling parameter monitoring system and method of this invention effectively solve practical production needs such as large hook suspension load, large upper and lower shackle calibration tension value, large number of mud tanks, high drilling engineering parameter acquisition response rate, and integrated display of comprehensive information for 10,000-meter drilling rigs. It ensures the accuracy, timeliness, and availability of monitoring drilling engineering parameters such as hook suspension load value, upper and lower shackle calibration tension value, and mud tank liquid level value for 10,000-meter drilling rigs, provides high-quality drilling engineering data support for drillers, and improves the drilling construction efficiency of 10,000-meter drilling rigs.

[0025] The present invention provides a method for monitoring drilling parameters of a 10,000-meter drilling rig, such as... Figure 4 As shown, the specific steps include the following: S1: Configure the functional module ID addresses of the first and second data acquisition boxes; configure the IP addresses of the first wireless node, the second wireless node, the electrical control PLC, and the OPC server. After the hardware connection is completed, based on CAN communication technology, the communication control protocol of the communication control module in the first and second data acquisition boxes is designed. This mainly includes the data frame structure, command frame structure, CAN node object ID encoding rules, data transmission baud rate, and data query method, so as to realize the data acquisition and uploading and control command issuance of the drilling parameter monitoring system of the 10,000-meter drilling rig. According to the CAN node object ID encoding rules, the ID address of each functional module is uniformly encoded and configured. Ensure reliable wiring between the OPC server and the first data acquisition box, the OPC server and the electrical control PLC, the first data acquisition box and the first wireless node, and the back-end server in the drilling engineer's office and the second wireless node. Establish a local area network (LAN) environment, using the TCP / IP network protocol for data communication. Design the corresponding IP addresses for the OPC server, the first data acquisition box, the electrical control PLC, the first wireless node, the back-end server, and the second wireless node, ensuring that all LAN-connected objects have IP addresses within the same IP segment. Configure and verify the designed IP addresses in each LAN-connected system.

[0026] S2: Set the monitoring parameter sampling period, set the display drilling parameters, parameter display range, subdivision scale value, and alarm threshold in the OPC server; and test and verify the button function, parameter correction function, and selection function, and set the function parameters. According to the drilling requirements of the 10,000-meter drilling rig, the sampling period for the hook suspension weight parameter and riser pressure parameter is designed to be 120ms. The sampling period for key monitoring parameters is required to be taken 3 times within 1 second, and the sampling period for general monitoring parameters is required to be taken once within 1 second. The sampling period designed for the monitoring parameters of the drilling parameter monitoring system is set accordingly in the OPC server acquisition software. The drilling parameter monitoring system for the 10,000-meter drilling rig needs to monitor the direct and derived parameters. Direct parameters include: hook weight, standpipe pressure, tong torque, mud return volume, pump stroke, rotary table torque and speed, top drive torque and speed, hook height, and mud level in the mud tank. Derived parameters include: drilling pressure, pump stroke count, mud outlet flow rate, rope work, well depth, drill bit position, drilling time, and hook speed. In the OPC server software, the display range, subdivision scale value, and alarm threshold of each direct and derived parameter should be set individually.

[0027] The button functions, parameter correction functions, and selection functions were tested and verified. The function parameter settings were as follows: The button function test and verification includes: zeroing the drilling pressure, drilling to the bottom, starting and stopping the pump flushing counter, zeroing the overflow and leakage, and zeroing the volume difference of the active pool. The parameter correction function test and verification includes: hook height modification, drill bit position modification, well depth modification, pure drilling time correction, and wire rope work correction; The selected function test verification includes: selection of total pump stroke count, selection of pump stroke counter, and selection of active pool; Functional parameter settings include seat card threshold settings.

[0028] S3: The first and second data acquisition boxes collect data from each sensor and provide the data source to the OPC server via CAN communication and network communication. S4: The parameters are displayed in a unified manner on the OPC server, PLC, and back-end server. Alarms are triggered or information is pushed to relevant personnel for abnormal data.

[0029] In the OPC server, configure the real-time monitoring direct measurement and derived drilling engineering parameters that need to be centrally displayed. Select the alarm notification method according to the drilling engineering parameters. Alarm notification methods include: voice broadcast, pop-up notification, and color differentiation of display values. The integrated display of comprehensive drilling engineering parameter information includes numerical method, curve method, scale method, bar chart method, and actual working condition method. Real-time drilling engineering parameters, alarm notifications, and integrated information display methods can all be configured in the OPC server, electrical control PLC, and back-end server. In practical applications, general settings are made in the OPC server, and personalized fine-tuning settings are made in the electrical control PLC. No corresponding settings are made in the back-end server, only information is displayed.

[0030] After the sensors in the first and second sensor packages collect data, the data is transmitted to the first and second data acquisition boxes, respectively. The OPC server reads the rotary table torque and speed, and top drive torque and speed signal data of the 10,000-meter drilling rig and transmits them to the electrical control PLC. The electrical control PLC reads the drilling monitoring parameters of the 10,000-meter drilling rig and displays them on the touch screen, which is installed in the driller's cabin. At the same time, the control commands generated by the instrument interface operation on the touch screen are read by the OPC server of the 10,000-meter drilling rig drilling parameter monitoring system. The monitoring parameters read by the OPC server are transmitted back to the data interface conversion module of the first data acquisition box via the bus. The data is then transmitted to the first wireless node via the interface conversion module. The second wireless node receives the data from the first wireless node and transmits it to the backend server. The backend server synchronously displays the drilling monitoring parameters during the drilling process of the 10,000-meter drilling rig. The integrated display of drilling engineering parameter information is presented in numerical, curve, scale, bar chart, and actual working condition formats. When the monitored parameters exceed the preset alarm threshold, an alarm is triggered by voice broadcast, pop-up prompts, and color-coded display values. The drilling parameter monitoring of the 10,000-meter drilling rig is completed.
