As the world enters an era of unprecedented innovation-intensive and industrial transformation, the harbinger of a revolutionary breakthrough in science and technology is becoming more apparent. The accelerated penetration of information technology into other fields and the development of deep applications will lead to a new round of information industry transformation characterized by intelligence, ubiquity and integration, leading the development of mechanical products to the direction of intelligence. The tremendous pressure of deep adjustment of the growth model will promote new environmental protection and energy-saving technologies, new energy technologies to accelerate breakthroughs and widespread application, and promote the green development of mechanical products. At the same time, major technological innovations will appear more in the interdisciplinary field, and the integration of various technologies will become more frequent, which will lead to new technological system changes, major discipline breakthroughs, and a new round of scientific and technological revolutions and industrial revolutions. It can be expected that in the next 5 to 20 years, these technologies will undergo major innovation breakthroughs, and it will likely lead to tremendous changes in mechanical engineering technology and promote the development of the machinery industry in the direction of green, intelligent and service. The next 20 years is a key historical period in which China's manufacturing industry has become stronger and stronger, and it has established itself as a world leader. The China Mechanical Engineering Society has compiled the "China Mechanical Engineering Technology Roadmap", which not only proposes technical roadmaps in 11 fields, but also On the basis of it, a number of major technical issues that can affect the development of the machinery industry and even the manufacturing industry are major, leading and iconic. Creative, modeling, and optimized design techniques for complex systems Modeling, simulation, optimization and collaborative management are the core and key to the constant mechanical design technology. Complex electromechanical systems have complex hierarchies. The subsystems, subsystems and elements that make up a complex system are relatively independent and related. The superior system has properties and functions that are not available in the subordinate system. Complex electromechanical systems are often highly integrated with physics and information technology in many fields such as machine, electricity, liquid, and control. They are characterized by multiple levels, multiple objectives, multiple time and space, high dimensionality, nonlinearity, uncertainty, and openness. With the integration of computing, communication, sensing, control and other technologies, complex electromechanical systems will further exhibit technical features such as intelligence, networking, composite, distributed and embedded. Since the beginning of the 21st century, the level of demand that complex electromechanical products have to satisfy has become more and more diverse. How to effectively integrate the cultural and emotional needs of users into the creative design of complex electromechanical products is a subject that people need to continue to explore. Europe, the United States, Japan, South Korea and other countries have developed a design development plan and industrial cluster model that conforms to regional culture and emotions. The United States has established a Silicon Valley represented by technology and Internet culture. Europe has developed a blend of modern technology and traditional brand culture. product. The creative design technology integrating culture and emotion belongs to the new technology of multi-disciplinary integration. The key technologies include: creative cognition and collaborative design technology, emotional expression and evaluation technology, cultural brand, cultural composition and multicultural integration design technology. Aerospace equipment, large-scale transportation vehicles, precision manufacturing and processing equipment, complete sets of material processing equipment, engineering machinery, micro-nano machinery, and optoelectronic communication equipment are complex electromechanical systems, mastering complex electromechanical systems, modeling, simulation and optimization design. Technology will definitely enhance the independent design capability of China's major equipment and the technological innovation capability of China's machinery industry. In the 1990s, computer-aided design, computer-aided engineering, computer-aided manufacturing, and product data management (C3P: CAD/CAE/CAM/PDM) technology became popular in the international industry, and related software became product modeling, simulation, and optimization. Missing tools. In the past 10 years, in order to meet the design requirements of complex electromechanical products, C3P has developed into M3P, namely multibody system dynamic design, multi-discplines colaberative design, multi-domain physical modeling based on constitutive fusion. (Multi-domain physical Modeling) and full lifecycle management (PLM) technologies form the next generation of technical features for today's computer-aided product modeling, simulation, optimization and management. The complex technical system marked by information physical integration is actually a unity of computing process and physical process. It is a new generation intelligent system integrating computing, communication and control. Modelica, a multi-domain unified modeling language developed by European scholars, has a domain-independent general-purpose model description capability that enables seamless integration between subsystem models in different domains of complex systems. The American-led domain scholars proposed the Cyber-Physical System (CPS), which aims to realize unified modeling, simulation analysis and optimization of multi-domain devices such as computing, communication, measurement and physics under a unified framework. Based on Modelica 3.0, the International Multi-domain Physical Unified Modeling Association recently introduced Modelica3.3, a multi-domain physical expression specification, which aims to support networked, distributed, embedded system modeling and simulation. China has launched a follow-up research project entitled "Three-dimensional Functional Prototype Design Platform for Supporting Industrial Embedded Application Modeling and Simulation". The development and popularization of CPS-based complex technology system modeling, simulation and optimization technologies will greatly accelerate the transformation and upgrading of equipment in the fields of automotive, aerospace, defense, industrial automation, precision instruments, and major infrastructure, and continuously improve its market competitiveness; It will spawn a number of functional innovations with computing, communication, control, synergy and autonomous performance, and even generate new industries.

When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas. Drilling BOP And Control System,Double ram blowout preventer, single ram blowout preventer, annular blowout preventer, blowout preventer control system Rugao Yaou Import & Export Trade Co., Ltd , https://www.ntyaous.com
Its types are divided into ordinary blowout preventer, universal blowout preventer and rotary blowout preventer. The universal blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotary blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, universal blowout preventers and rotary blowout preventers are often added, so that three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer. During operation, a sealed annular space is formed between the pipe string and the wellbore. When there is a pipe string in the well, it can also be separated The well is closed, but it will not work after several times of use, and long-term shut-in use is not allowed.
