Description

Technical Field

[0002] In recent years, relying on the group company's promotion projects, continuous tubing technology has achieved vigorous development, the equipment's technical level and service guarantee capabilities have been greatly improved, and the scope of application has been expanded to completion, logging, reservoir transformation, acid fracturing, well washing, well repair and other construction operations. The number of continuous tubing operation machines in various oil fields has increased rapidly, and a preliminary scale effect has been formed, but it has also caused a serious shortage of high-tech continuous tubing practitioners.

[0003] On the other hand, more diverse operation processes and more complex bottom hole conditions (long horizontal sections, high confining pressure, high temperature, multiple sets of transformers, etc.) have led to a sharp increase in the risk of wellbore operations. The traditional working mode based on "ground data + manual experience" to judge the downhole conditions has limited the further development of the "universal" attribute of coiled tubing technology. For the drilling and grinding process, the drilling and grinding operation process design is complex and the operation risk is high. The technical knowledge involved covers various aspects such as pipe string mechanics, hydraulic parameters, tools and processes. In the actual construction process, due to the differences in complex conditions such as wellbore trajectory, wellbore conditions, sinusoidal bending and spiral buckling of coiled tubing, the drilling pressure value estimated according to the construction design is inconsistent with the actual drilling pressure value loaded on the drilling and grinding tool. The accuracy and pertinence of construction decisions based on personnel experience are poor, and there is a lack of effective guidance for on-site construction. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] In order to facilitate the understanding of the technical solution provided by this application, the relevant contents of the technical solution of this application are first explained below. With the rise of global big data, Internet of Things, digital twins and other technologies, the use of digital and intelligent means to comprehensively cultivate high-quality continuous tubing technical talents, improve the degree of refinement of continuous tubing technical operations, and promote the large-scale promotion of technology has become a new hotspot.

[0064] The coiled tubing drilling and grinding process is a common process for horizontal well operations, involving equipment operation, downhole tools, operating processes and other aspects. The working conditions are complex and changeable, and the requirements for on-site technicians are extremely high. With the large-scale application of coiled tubing technology in the exploration and development of shale gas and tight oil and gas reservoirs, there is a serious shortage of high-tech practitioners; on the other hand, more complex bottom hole conditions lead to a sharp increase in the risk of drilling and grinding operations (including self-locking, resistance, stuck drill, stuck, etc.). In response to this problem, the present invention innovatively combines coiled tubing technology and digital twin technology, and simulates the state changes of components such as coiled tubing and tools during coiled tubing drilling and grinding operations by establishing a dynamic response digital model of the coiled tubing drilling and grinding process. On the one hand, it is used for the training of high-tech personnel, improving the technical level of on-site operations, and reducing the risks of coiled tubing operations caused by human factors; on the other hand, a downhole digital twin of drilling and grinding is established, which is subsequently combined with downhole measurement parameters to present the changes in the bottom hole state in real time, change the "ground data + manual experience" operation mode, provide a basis for scientific decision-making in coiled tubing operations, and provide technical support for the automation and intelligence of equipment.

[0065] The present invention establishes a dynamic response digital model library that is similar to the real scene by analyzing the equipment operation, tool configuration, process control, fault handling, downhole working conditions and other processes of the continuous tube drilling and grinding process, and develops three-dimensional (3D) simulation software based on the model. The digital model obtains the operator's operation information in real time, calculates the state changes of various components, tools and other components, and the data drives the simulation software 3D model to present animation effects that are similar to the real state. This method can provide a digital training platform for drilling and grinding technology for on-site personnel, and also provide technical support for the accurate judgment of the downhole working conditions of the subsequent drilling and grinding process and the realization of process closed-loop control.

[0104] Specifically, the corresponding classical mechanics model and fluid model are selected according to different operation scenarios. Under different operation scenarios, the classical mechanics model and fluid model are trained, derived and the model parameters are corrected according to the actual operation data to construct a digital dynamic simulation model of the drilling and grinding process.

[0105] Step 206: Calculate the voltage signal and configuration parameters through the digital dynamic simulation model of the drilling and grinding process to obtain simulation data.

With respect to the drilling and grinding process, the changes in the state of the tool string in the wellbore are analyzed. Through the numerical changes of load, wellhead pressure, circulation pressure, and pump displacement, as well as the simulated visualization of debris generated when the drill bit contacts the bridge plug in the wellbore, whether the drill is stuck, whether the drilling of the bridge plug is completed, etc., real feedback of the drilling and grinding operation is achieved.
