Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas drilling, and in particular to a driller's pilot instrument and system. Background Art

[0002] At present, drillers' on-site operations still mainly rely on observing the weight indicator, drilling rig equipment parameters, and logging display screens. The observed parameter information is numerous and not centralized, resulting in high work intensity. Operations in risky well sections mainly rely on their own experience, and the safety and speed of wellbore engineering cannot be guaranteed.

[0003] Although the driller's navigator can automatically identify downhole working conditions and provide the driller with an electronic parameter indicator of the optimal drill bit operating parameters, recommending the optimal drill bit operating parameters without human intervention, it cannot fully utilize the big data resource advantages of the EISS (Engineering Intelligent Support System) system, cannot achieve voice prompts as the main function and pictures as the auxiliary function, and cannot push engineering warnings, risk warnings, template execution, on-duty prompts, and EISC (Engineering Intelligent Support Center) command information.

[0004] The Chinese patent application number "CN201921158851.3," titled "A Drilling Site Electronic Station Instrument," discloses a system comprising: a camera for real-time monitoring of the fluid level in the drilling site overhead tank and buffer tank; a sensor group for online detection of the fluid volume in the drilling fluid pool and buffer tank, as well as the concentration of hydrogen sulfide gas in the buffer tank; and an early warning control system connected to the camera, sensor group, and integrated mud logging unit. Based on video information captured by the camera, sensor information detected by the sensor group, and information from the integrated mud logging unit, the early warning control system monitors the fluid level and hydrogen sulfide content in the drilling site overhead tank, as well as the volume of the drilling fluid pool, in real time. It automatically calculates the volume change, the rate of change over time, and its trend. This improves the station environment, reduces labor intensity, mitigates operational risks, avoids occupational injuries, and effectively enhances well control safety at the drilling site. However, the device only involves online detection of the liquid volume in the drilling fluid pool and buffer tank, and the concentration of hydrogen sulfide gas in the buffer tank, and does not have the function of reducing the false alarm rate of early warning and intelligently assisting the driller's operation.

[0005] Therefore, it is necessary to design a driller pilot system to effectively improve the on-site management and control capabilities, reduce the complexity of faults, and intelligently assist the driller in operations. Summary of the Invention

[0018] In an exemplary embodiment of one aspect of the present invention, the display under the drilling condition can be divided into real-time simulation of drilling, drilling speed, and drilling hook load curve, and intelligently display drilling risk prompts; according to the changes in real-time logging data and the measured wellbore trajectory, voice prompts are given for the drilling blockage risk, whether the drilling speed meets the well control requirements, and whether the grouting is normal.

[0019] In an exemplary embodiment of one aspect of the present invention, the display under the circulation working condition can be divided into wellbore data and real-time logging data. Different wellbore volume parameters are displayed according to the changes in the real-time logging data, and the circulation-related time is updated in real time according to the real-time data displacement; voice prompts are given to the driller when the EISS real-time data alarm is still for too long or the pump is not turned on at the bottom of the well for a long time.

[0030] The liquid level monitoring under the condition of sensor failure can be manually input through the handheld device or flat panel display to ensure the continuity of the liquid level monitoring record;

[0031] The liquid level guard in abnormal situations can send out a warning when overflow or well leakage occurs, and inform the liquid level guard personnel. The liquid level guard personnel will make a judgment and handle it. If it is a false alarm, click to end the warning; if it is an abnormality, record it; if the guard personnel do not handle it within 3 minutes, it will be automatically pushed to the on-duty cadre and / or driller for processing.

[0044] Hereinafter, the driller pilot instrument and system of the present invention will be described in detail with reference to exemplary embodiments.

[0045] It should be noted that “first”, “second”, etc. are only for the convenience of description and distinction, and cannot be understood as indicating or implying relative importance.

[0046] In a first exemplary embodiment of the present invention, a driller pilot is provided.

[0047] The driller pilot instrument can receive the filling records, real-time logging data, risk well section data, EISC instructions and liquid level sitting records from the drilling engineer platform to analyze and determine the current working conditions.

[0048] The interface is displayed according to the current working conditions, and the driller's operation is given engineering warnings, risk warnings, indicator comparisons and instruction measures, intelligently assisting the driller's operation.

[0049] Furthermore, the risk section data can be set manually, and the early warning prompt can be made through voice broadcast and / or information prompt.

[0050] like Figure 1 As shown in the figure, the working principle of the driller pilot is as follows:

[0051] The driller pilot instrument uses basic data provided by the drilling work platform, mud logging work platform and drilling fluid work platform in the well site version of the EISS system, mainly including manually filled data in the three disciplines.

[0052] In addition to manually entered data, the system also combines real-time mud logging data, fluid level records, and various manually set parameters for risky well sections. Through intelligent backend analysis and combined with instructions from EISC experts, various engineering warnings, risk alerts, indicator comparisons, and instructional measures are generated in the driller's pilot instrument. These warnings can be provided through voice broadcasts and / or text prompts.

[0053] In this exemplary embodiment, the driller pilot instrument may include an explosion-proof touch screen computer, a CPU, a solid-state drive, a wireless network card, a high-definition camera, a microphone, an audio system, and a power supply.

[0054] The explosion-proof touchscreen all-in-one computer primarily displays the EISS system and also serves as a carrier for associated hardware. The CPU primarily processes the various algorithms built into the driller's navigation system. The solid-state drive caches some data, facilitating data copying and transmission while also increasing data read, write, and processing speeds.

[0055] The wireless network card is a necessary component for the explosion-proof tablet to connect to the wireless network when wired network transmission is unavailable.

[0056] The high-definition camera is used for video calls between the driller and the EISC expert, so that the expert's key instructions can be directly transmitted to front-line employees.

[0057] The microphone is used to collect surrounding audio, mainly for video and voice calls; the power supply is used to provide power for the driller's pilot instrument.

[0058] In this exemplary embodiment, Figure 2 As shown in , the driller pilot instrument may include interface displays and voice prompts under three working conditions: drilling, tripping and circulation.

[0059] In this embodiment, the drilling status display is divided into wellbore data and real-time data. Based on changes in real-time logging data, the driller is given voice prompts regarding whether drilling parameters meet the speed-up template (weight on bit, rotational speed, displacement), EISS real-time data alarms (torsion anomaly, overflow, lost circulation, hydrogen sulfide, gas logging anomalies, abnormal casing pressure), excessive idle time, prolonged bottomhole pump inactivity, and EISC instructions. A total of 11 early warning functions and services are provided for drilling status.

[0060] In this exemplary embodiment, the tripping condition displays real-time tripping simulation, tripping speed, and tripping hook load curves, along with intelligent tripping risk alerts. Based on real-time logging data changes and the measured wellbore trajectory, voice prompts are provided regarding tripping sticking risks, whether the tripping speed meets well control requirements, and whether grouting is normal. A total of 17 early warning services are available for the tripping condition.

[0061] In this exemplary embodiment, the Circulation mode displays wellbore data and real-time logging data. Based on changes in real-time logging data, different wellbore volume parameters are displayed, and circulation-related times are updated in real time based on real-time displacement data. Voice prompts are provided to the driller for EISS real-time data alarms (e.g., overflow, lost circulation, hydrogen sulfide, gas logging anomalies), prolonged downhole pumping, and other conditions. The Circulation mode provides a total of four early warning services.

[0062] In a second exemplary embodiment of the present invention, a driller pilot system is provided, the driller pilot system comprising any one of the above driller pilots, a collector, an electronic liquid level monitor and a handheld device, wherein:

[0063] The collector can collect, store and transmit data from drilling and downhole operation sites;

[0064] The electronic liquid level monitoring instrument can track and display the liquid level data in the circulation tank in real time and share the driller's pilot instrument;

[0065] The handheld device can be used by personnel on duty at the liquid level to calibrate, check and modify the liquid data in the circulation tank.

[0066] The collector is capable of collecting, storing, and transmitting data from drilling and downhole operations. Specifically, the collector serves as a carrier device for storing manually entered data, real-time data, audio and video data, and other data from drilling and completion operations. It integrates data collection, storage, transmission, and computation for multiple professional and diverse equipment types on-site, enabling unified management and control of drilling and downhole operation site data. The device features data collection, data storage, wellsite networking, video surveillance, video conferencing, VoIP, and remote operation and maintenance management for drilling and downhole operations. It also offers on-site port data flow analysis, lightweight network security defense, hardware chip-level encryption and decryption, remote monitoring of equipment status, and remote operation and maintenance management.

[0067] The electronic liquid level monitoring instrument can track and display the liquid level data in the circulation tank in real time and share it with the engineer platform. For example, by adding an explosion-proof display to the circulation tank, the liquid level monitoring record is digitized. It also integrates functions such as real-time liquid level data tracking, tripping and drilling fluid correction tables, return flow records, well control warnings, and historical data query, achieving paperless and intelligent office work for monitoring personnel.

[0068] The handheld device allows personnel on duty to check, inspect, and modify the liquid data in the circulation tanks. Specifically, the personnel on duty can use the handheld device to check the liquid level of each circulation tank. If the volume reading displayed on the handheld device is consistent with the scale, they click the confirmation button and the data is synchronized to the electronic liquid level meter. If the displayed reading is inconsistent with the scale, the personnel on duty can manually modify it, save it, and then synchronize it to the electronic liquid level meter.

[0069] In this embodiment, if Figure 5 As shown in , the driller pilot system may also include an engineer platform, which is configured to enable the instructions issued by various professional engineers on site to be voice broadcast on the driller pilot. The engineer platform may include: at least one of: a drilling engineer platform, a logging engineer platform and a drilling fluid engineer platform.

[0070] The driller pilot system primarily consists of a driller pilot and an electronic level monitoring system. The driller pilot performs big data analysis based on EISS system engineering data and pushes the resulting engineering pre-alarms, engineering prompts, and EISS system instructions and measures to the driller's operating platform, assisting the on-site driller with engineering operations and providing prompts. Overflow and well leakage alarms generated by the electronic level monitoring system are also simultaneously pushed to the driller pilot system for voice prompts to the on-site driller. Furthermore, the driller pilot system interacts with the on-site engineer platform, and instructions issued by each specialized engineer platform can be played back in the driller pilot.

[0071] In this exemplary embodiment, the electronic liquid level monitor may include a scale displacement sensor, an explosion-proof touch screen, and early warning software.

[0072] The scale sensor, based on the rise and fall of the liquid level scale above the circulation tank, collects and transmits the signal from the scale's movement to the liquid level monitoring system via a thin steel wire and displacement sensor. The explosion-proof touch screen primarily serves as a platform for the electronic liquid level monitoring system, allowing operators to use it to enter and process data. It also serves as a platform for installing and displaying the early warning software. The early warning software analyzes the real-time liquid level data transmitted by the liquid level sensor in the electronic liquid level monitoring system according to pre-set rules and displays the warning results on the explosion-proof touch screen.

[0073] In this exemplary embodiment, the electronic liquid level monitoring instrument may include four contents: liquid level monitoring during the drilling stage, liquid level monitoring during the drilling and drilling stage, liquid level monitoring in the event of sensor failure, and intelligent early warning in abnormal situations.

[0074] Among them, the liquid level guard during the drilling stage changes the original paper-filled liquid level guard record of the guard personnel to using a handheld device to punch in and verify whether the electronic reading is consistent with the scale reading. If the total pool volume changes, the reason for the difference will be marked in the system.

[0075] The liquid level monitoring station during the drilling phase also retains manual records for monitoring and verification, and the "dual track" is in parallel to ensure the accuracy of the drilling liquid level data.

[0076] The liquid level monitoring in the event of a sensor failure can be manually input via a handheld device or a flat panel display to ensure the continuity of the liquid level monitoring record.

[0077] like Figure 4 As shown in the , the liquid level guard under abnormal circumstances can issue a warning when an abnormal situation such as overflow or well leakage occurs, and inform the liquid level guard personnel. The liquid level guard personnel will make a judgment and handle it. If it is a false alarm, click to end the warning; if it is an abnormality, record it; if the guard personnel do not handle it within 3 minutes, it will be automatically pushed to the on-duty cadre / driller for processing.

[0078] In this exemplary embodiment, the collector may include a data acquisition module, an industrial networking module, a video conferencing module, a VoIP module, a video monitoring module, an industrial power supply module, and a management and operation monitoring module.

[0079] Among them, the data acquisition module: serves as the access point for on-site real-time data and manual data, collects and transmits data, and can also collect real-time data from on-site intelligent instruments, various signal transmission sensors and other professional PLC systems.

[0080] Industrial Networking Module: Meets networking requirements for diverse scenarios and enables rapid deployment, including uplink access capabilities for satellite, wired, and 4G networks, and downlink LAN wired and wireless networking requirements. This module offers wired and wireless connectivity, multiple VPN access capabilities, LAN connectivity, WiFi interfaces, bridge-based connectivity, device management systems, and device status reading.

[0081] Video conferencing module: Because the backend expert system within the EISS system requires remote supervision and command through a custom-developed audio and video scheduling module, this module was developed based on the group company's existing Polycom video conferencing system. The data collector video conferencing module ensures full compatibility and seamless integration with the group company's existing video conferencing system. The data collector video conferencing module requires a USB-C port.

[0082] VoIP Module: The backend expert system and RTOC monitoring center within the EISS system rely on a custom-developed VoIP voice intercom scheduling module to provide remote voice support and supervisory control directly with the explosion-proof intercoms of mobile workers on-site. The collector's VoIP voice intercom scheduling module enables data interconnection and seamless voice communication with existing explosion-proof intercoms at the wellsite.

[0083] Video Surveillance Module: The data collector's video surveillance module seamlessly integrates with existing video surveillance cameras at the wellsite, providing a remote access interface for the EISS system. It supports up to three channels of surveillance. Local storage and historical playback of surveillance data are provided for at least 30 days. Due to the varying network environments at wellsites, the video surveillance module must support fusion video transmission to ensure that live video can be transmitted back to the base center even when network bandwidth is limited (e.g., satellite networks or poor 4G wireless signals).

[0084] Industrial power module: built-in redundant AC / DC power converter, built-in battery capacity ≥80Wh;

[0085] The battery pack has intelligent charge and discharge protection control; input voltage: adaptable to 100~260V AC.

[0086] Operation Monitoring Module: Provides reliable predictive status support for remote operation and maintenance personnel, with local operation status monitoring and remote management support functions. Supports remote control of the data acquisition module, industrial networking module, video conferencing module, VoIP module, and video surveillance module.

[0087] Here, the collector can transplant the well history data to the platform for filling in, and transmit the real-time working conditions to the background management; integration, various calculations, and real-time simulation tools provide all-round support.

[0088] In this exemplary embodiment, Figure 3 As shown in , the electronic liquid level on-duty instrument can also be used by on-duty personnel to verify liquid level data, analyze the causes of differences, and record outlet observations to form electronic liquid level on-duty records.

[0089] In this exemplary embodiment, the risk prompt may include:

[0090] Combined with the drilling dynamic parameters, risk warnings are issued when drilling through the reduced diameter section, large dogleg section, bell mouth, casing shoe, and steps inside the casing.

[0091] In this exemplary embodiment, the speed-up template may include:

[0092] Real-time analysis using the drilling knowledge base speed-up template indicates whether the drilling pressure, rotation speed, and displacement meet the block template requirements, effectively improving on-site management and control capabilities, helping to reduce the complexity of faults, and helping engineers and drillers better understand the downhole situation, providing strong support for the digitalization and informatization transformation of drilling projects.

[0093] In order to better understand the above exemplary embodiments of the present invention, they are further described below with reference to specific examples.

[0094] The driller pilot system has been tested on site in 16 wells, including PS8, PS12, and MX019-H2. It has accumulated more than 8,000 hours of operation on site and more than 600 voice prompts. It has eliminated accidents caused by low-level operational errors, assisted the drilling team in speeding up the template execution rate, significantly reduced the fault complexity rate, and taken a key step towards intelligent drilling.

[0095] It realizes early warning of engineering complexities such as overflow, lost circulation, blockage, twisting, sulfur abnormality, casing abnormality, long static time, and long time without pump at the bottom of the well under the three working conditions of drilling, circulation, and tripping; combines the dynamic parameters of drilling to issue risk warnings for tripping through the reduced diameter section, large dogleg section, bell mouth, casing shoe, and step inside the casing, and uses the drilling knowledge base speed-up template for real-time analysis to prompt whether the drilling pressure, speed, and displacement meet the requirements of the block template, effectively improving the on-site management and control capabilities, helping to reduce the complexity of faults, and helping engineers and drillers to better understand the downhole situation, providing strong support for the digitalization and informatization transformation of drilling projects.

[0096] Table 1 compares the statistics of well leakage and overflow warnings for wells PS8, PS9, and PS12 without the use of the electronic liquid level monitoring system and with the use of the electronic liquid level monitoring system. As shown in Table 1, after the use of the electronic liquid level monitoring system, the number of well leakage warnings, overflow warnings, missed alarms, and false alarms were greatly reduced, and the total false alarm rate was reduced by 98.7%.

[0097] Table 1 Statistics of well leakage and overflow warning

[0098]

[0099] Furthermore, the digital drilling team at Well PS8 was deployed for over 120 days, covering the drilling and completion phases, monitoring 14 runs and generating 286 voice prompts. This provided accurate, real-time decision support for key operations such as drilling, tripping, and circulation. This helped reduce well modification complexity by 36%, increased overall drilling speed by 18%, and shortened the drilling cycle by 21 days, achieving optimal technical performance in the Penglai gas field. The non-digital drilling team at Well MX019-H2 was deployed for over 50 days, covering the drilling phase, monitoring 7 runs and generating 175 voice prompts. During this period, the driller's pilot accurately issued a voice prompt within 7 minutes, compared to manual observation of the backtracking curve. This saved time for identifying and addressing the lost circulation.

[0100] In summary, the beneficial effects of the present invention include at least one of the following:

[0101] (1) The driller's pilot instrument, electronic liquid level monitoring system and engineer platform work together to form a "three-in-one" wellbore protection system, which greatly reduces the false alarm rate of the original early warning, helps engineers and drillers better understand the downhole situation, and effectively avoids the problem of the driller's attention being distracted and judgment being impaired due to lack of concentration;

[0102] (2) The electronic liquid level monitoring instrument can automatically generate electronic liquid level monitoring records, which are easy to view, convenient for statistics, and suitable for long-term storage. In the event of an emergency, experts on site and in the EISC center can quickly retrieve the liquid level monitoring record book for analysis, which can realize the sharing of front-end and rear-end data, assist in pre-analysis, in-process processing and post-investigation, and use "real-time data + human participation" to significantly reduce the false alarm rate of early warnings;

[0103] (3) The false alarm rate for well leakage, overflow, etc. is reduced by more than 90%. After full promotion, it is of great significance to reduce the complexity of accidents and consolidate well control responsibilities. According to the statistical analysis of the early digital trial operation data, after full promotion, it can help increase drilling speed by about 2% and reduce the complexity rate by about 3%, and the effect of improving quality and efficiency is outstanding.

[0104] Although the present invention has been described above with reference to the exemplary embodiments and the accompanying drawings, it will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the spirit and scope of the claims.
