Description

Technical Field

[0001] The present invention relates to the technical field of collaborative drills, and in particular to a desktop deepwater well-killing and well-control multi-position collaborative drill system and method. Background Art

[0002] Oil drilling refers to the process of using specialized drilling equipment and techniques to drill a cylindrical hole of a specific diameter downward or to the side of a surface location where oil reserves have been discovered, and then reach the underground oil and gas formations. Oil and gas extraction requires a proficient understanding of the professional knowledge and operational skills of oil drilling. Downhole operations are a technical means of ensuring the normal production of oil and water wells during oilfield exploration and development. They involve workovers performed to maintain long-term normal production.

[0003] However, new oilfield employees and students majoring in petroleum phase pressure have little intuitive understanding of the drilling process, downhole operations, or accident handling methods, and are unfamiliar with on-site downhole operations. Operational errors or carelessness can lead to serious quality or safety incidents, resulting in significant losses for the nation and its people. Therefore, on-the-job knowledge and professional skills training for drilling personnel is crucial. However, since nearly all drilling sites and facilities are located in the field, on-site training is impossible. Relying solely on conventional classroom instruction or laboratory exercises, lacking immersive and engaging teaching methods, inevitably results in dull and boring course content, poor student learning outcomes, and a failure to achieve the desired training results.

[0004] The invention patent application document, application number CN202110108995.3, describes an underwater blowout preventer system and method for deepwater rescue well killing. It states that deepwater (water depth greater than 500 meters) has significant oil and gas reserves and good technical and economic potential. However, deepwater oil and gas production is characterized by long offshore distances, harsh environments, concentrated personnel and facilities, and high-risk formations. Once a blowout occurs, it can easily trigger a chain reaction, making emergency rescue extremely difficult. Improper handling can cause economic losses, casualties, environmental pollution, and even catastrophic consequences, presenting a disruptive risk that companies cannot afford. Rescue wells are a last resort for uncontrolled blowouts and an effective emergency well control solution. The success of the well killing process after the rescue well is connected is crucial to the success of the entire rescue well drilling operation. Conventional rescue well killing techniques, due to the U-tube effect and inefficient killing fluid supply, can lead to well killing failures or even uncontrolled rescue well blowouts.

[0005] Therefore, the well control level of personnel working in deepwater underground pressure wells is particularly important. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art in that the well control level of downhole pressure personnel is unstable and the training effect is poor, and to provide a desktop deepwater well pressure well control multi-position collaborative drill system and method.

[0047] Data analysis module: connected to the well killing parameter setting module, calculates the choke line pressure loss under different conditions based on the drill results and well killing parameters.

[0048] In this embodiment, a parameter configuration module is also included for setting drilling parameters, including drilling tool structure, well depth structure, formation parameters and equipment parameters.

[0049] In this embodiment, the well killing parameters include water depth, choke line length and drilling fluid density.

[0050] A desktop deepwater well control multi-position collaborative drill method includes the following steps:

[0051] S1: Configure deepwater well control parameters and build a 3D deepwater well control model based on virtual reality technology;

[0052] S2: assign corresponding job information to the drill object through the main control module;

[0054] S4: The three-dimensional graphical status information of the terminal is displayed through desktop virtual display software, and the additional flow method is used to conduct multi-position drills for deepwater well pressure control.

[0055] In this embodiment, the S1 further includes:

[0056] S11: constructing a three-dimensional model using virtual reality technology, wherein the three-dimensional model includes: a drill scene model, a well control equipment model, a personnel model, an environmental condition model, and an accident development process model, and the joints of the personnel model are wired with at least three sections;

[0057] S12: Optimize the texture and material of the 3D model, and finally generate a 3D deepwater well control model.

[0058] In this embodiment, the positions in S2 include: driller, assistant driller, pump operator, driller, logging engineer, drilling supervisor, team leader, senior team leader and underwater engineer.

[0059] In this embodiment, the deepwater well control multi-position drill using the additional flow method in S4 specifically includes:

[0060] S41: Setting well killing parameters, including well killing fluid parameters and low-density liquid parameters;

[0061] S42: The staff on duty conducts a well-killing process drill based on job information and operating procedures.

[0066] In this embodiment, the low-density fluid is a low-rheology fluid with low density and low viscosity and compatible with drilling fluid.

[0067] Specifically, in this embodiment, trainees can interact with each other after entering a training program through a combination of desktop virtual display software and well control simulation hardware. During a training session, a group of operators can practice operating well control equipment on the hardware simulation device, while other process and equipment operations can be performed on the desktop virtual reality software.

[0068] All software systems are designed using an object-oriented approach. Key equipment at the drilling site (such as the top drive and downhole data) is described entirely using classes. The class attributes, events it can receive, and responses to these events are consistent with those of the real equipment, fully recreating the drilling site. Furthermore, to ensure that the simulation software reflects the results of data changes in front-end equipment in real time, the system utilizes a multi-threaded mechanism. Each time a job is executed, the parameter interface is the main thread, and the drilling process program is the child thread. These two threads share a virtual address space, forming a multi-tasking mechanism that seamlessly integrates software and hardware operations.

[0069] Specifically, in this embodiment, the software usage standards are as follows:

[0070] The modeling tool used is 3DSMAX;

[0071] The 3D graphics development tool uses Unity 3D;

[0072] Operating environment: Supports Windows 10 and above operating systems;

[0073] Polygon requirements: A moderate number of polygons is recommended to ensure smooth rendering. A high-polygon model should be created for normal baking to increase detail. All invisible polygons should be deleted to improve performance.

[0074] Mapping accuracy: Each model is drawn with at least 4 basic maps, normal maps, specular maps, and AO maps based on photo data;

[0075] Character modeling specifications: The character modeling joints must have at least 3 wiring segments. The character's mouth and eyeballs must be modeled separately, and eye and mouth movements can be made.

[0076] Export format: To ensure compatibility with graphics engines, it is required to export .FBX and .3DS format files;

[0077] The desktop multi-player drill system supports desktop single-player drill function.

[0078] Specifically, this system covers more than 100 drill items. Teachers can arbitrarily combine drill items according to training needs and customize the content of each drill. The processing process is as follows:

[0079] 1. Receive the master program initialization information from the drill task list, and after resetting the device status, generate the initialization scene and device status for each drill item;

[0080] 2. After the operation begins, the interactive operation information of multiple positions and roles is received. The main control program analyzes and processes it uniformly, and then synchronizes the 3D graphic status information of the display terminals of all participants through the unity3D network architecture, and simultaneously executes the commands sent by the main control;

[0081] 3. After the command is executed, the current scene status and completed command number required by the master are sent to the master;

[0082] 4. Once the graphics program is started, it can continuously receive data and perform operations, and supports repeated initialization and repeated operation functions.

[0083] It should be noted that the core of the mathematical model of the present invention is as follows:

[0084] The system software utilizes mathematical and physical models such as overflow models, drilling rate models, and well-killing models to simulate various operating conditions and parameter information in petroleum engineering drilling operations, such as pressure, torque, drilling rate, and displacement, accurately reflecting the relationships between these physical parameters to achieve the same results as actual drilling operations. The system supports various drilling parameter settings, such as drill tool structure, well depth structure, formation parameters, and equipment parameters, making the drill process more flexible and diverse, and the training more targeted. The mathematical and physical models used in the system support a non-sequential operation architecture, which can realistically simulate various operations during the operation and truly reflect the differences in human operations, making the system performance closer to reality.

[0085] During the drill, the system can reproduce the operation process, accident evolution process and parameter change process according to the actual operation of the trainees. It can achieve data similar to the real rules when different people use the system and operate in different processes.

[0086] Performance and event development: In the case of drilling into high-pressure formations, misoperation or improper handling, the system supports the triggering of well control accidents and the performance of accident phenomena.

[0087] The three-dimensional expression core of the present invention is as follows:

[0088] The 3D display system, the primary visual output for the entire project, leverages virtual reality technology to create a realistic perceptual environment. The system uses real-time 3D rendering animation, synchronized with operational conditions, to display operational feedback from trainees.

[0089] 1. The system uses the mainstream 3D graphics engine as the development platform and supports good VR environment interaction

[0090] Through immersive VR technology, three-dimensional simulation technology, and three-dimensional interactive technology, we construct drill scenarios, equipment and facilities, personnel conditions, environmental conditions, and the accident development process, and achieve simulation and three-dimensional interaction of the personnel situation handling process.

[0091] 2. The system allows for both individual and multi-person drills. The number of participants can be adjusted based on actual conditions. If the number of participants is insufficient, AI will automatically coordinate and execute any unattended positions.

[0092] 3. The system supports multi-person collaborative operation in desktop 3D display and VR immersive 3D display environment

[0093] Taking into full consideration the user's visual sensory acceptance of the 3D display system, users can choose desktop or immersive virtual reality display mode according to their personal situation when working in a multi-person team.

[0094] 4. Show the characters and actions of each job

[0095] The operating process of personnel in various positions is displayed in a variety of real-world environments (including desktop, immersive VR, mixed reality MR, etc.), including: real-time display of character operation movements, mechanical equipment movements, and personnel movement positions.

[0096] 5. Multiple roles and multiple windows display the operation process, scene close-ups, and personnel perspectives. At the same time, the operation process can be viewed from a third-person perspective, and the observer can independently choose the viewing location and angle.

[0097] 6. The system supports realistic sound effects. The sound effects of drilling equipment running, colliding, accelerating and decelerating in all drilling operation simulation pictures should be consistent with the actual sounds of the equipment on the drilling site, and the sound effects are realistic and close to the scene.

[0098] The development content focuses on key aspects related to offshore well control technology, with design and production focused on operational processes, well control measures, and team collaboration, truly enhancing trainees' operational capabilities. The system provides teacher-side management software, allowing teachers to categorize and manage system functions, training projects, student information, and exercise teams, and develop rapid implementation plans to facilitate daily training project setup.

[0099] The system integrates advanced computer technologies such as virtual simulation, embedded systems, the Internet of Things, and network communications to reflect personnel behavior and visualize the drill process in real time. It automatically evaluates the actual operational performance of each drill role and multi-person team, provides feedback on individual and team drill results, and analyzes data such as drill error rates. This truly achieves integrated intelligent training management from learning to assessment, from theory to practice, and from drill data to evaluation and analysis, demonstrating its high technological sophistication.

[0100] The system enables well control drills for various operations, enabling both single-person and multi-person drills. It also evaluates user handling operations, emergency response, task completion, and related knowledge points, identifying any issues or deficiencies during the drill. The system supports both single-person and multi-person drills, allowing for practice and assessment of drill projects. Trainees can assume the roles of operators and complete project training according to drill requirements. In team mode, multiple people collaborate to simulate the work process of a team. Role grouping can be assigned uniformly by the instructor or selected by the trainees.

[0101] According to their individual training positions, teachers will define the roles of students and allocate camera positions to carry out training project drills.

[0102] The foregoing description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein by the teachings above or by techniques or knowledge in the relevant field.
