【Major Chemical Equipment Innovations】In 2021, China’s first deep-sea production tree and control module were successfully manufactured
Thread Content
On September 5, 2021, China’s first deep-sea Christmas tree and control module were successfully produced by Chongqing Qianwei Technology Group. The subsea tree system is the core equipment for the production of offshore oil and gas fields. It connects the oil and gas from deep within the strata with external oil and gas transportation pipelines, allowing for control over the extraction rate of oil and gas, as well as real-time monitoring and adjustment of production levels. Its manufacturing process and quality level are directly related to the quality, safety, reliability, economy, and environmental sustainability of oil and gas field development. After years of relentless effort, the Avantgarde Group has overcome a series of domestic technical challenges, including high-pressure sealing, corrosion resistance, precision machining, deep-water wet electrical connections, as well as system design and analysis. This has ended the situation in which key core technologies for underwater oil and gas equipment in China were long monopolized by foreign companies, resolved the technical barriers imposed by those foreign firms, and enabled the localization of deep-sea production trees. This represents another important piece of equipment for the development of China’s marine oil and gas resources. As a company specialized in the design and manufacturing of components for oil and gas equipment, Nanjing Diwell is undertaking the project titled \"Research on the Selection of Corrosion-Resistant Materials for Subsea Christmas Trees and Optimization of Anti-Corrosion Coating Technologies.\" It is responsible for optimizing the properties of the materials used in the structure of subsea Christmas trees, as well as the materials used for anti-corrosion cladding and coatings. It also participated in the development of the first domestically produced set of deepwater production trees and control modules for the Avantgarde Group, carrying out the manufacturing of key components such as the production tree itself required for the project. In the future, Nanjing Diwell will continue to deepen its efforts in researching key technologies, making positive contributions to building a strong maritime nation and ensuring **energy security.
The subsea tree system is the core equipment for the production of offshore oil and gas fields. The subsea tree system is a core device in offshore oil and gas exploration. It mainly consists of three components: the subsea tree, the tubing hanger system, and the subsea control system. Its primary functions are to regulate the flow rate of the oil and gas produced or of the water and gas injected into the reservoir. It also monitors various parameters related to oil and gas wells, such as production pressure, annular pressure, temperature, sand production rate, and water content. This system connects the oil and gas coming from deep within the reservoir with external oil and gas transportation pipelines, allowing for control over the extraction rate of oil and gas as well as real-time monitoring and adjustment of production conditions. Its manufacturing process and quality level are directly related to the quality, safety, reliability, economy, and environmental sustainability of oil and gas field development. Previously, all the subsea Christmas trees used in our country were monopolized by foreign companies. Over the course of 11 years, Chongqing Qianwei Technology Group invested hundreds of millions of yuan in research and development efforts. By overcoming a series of technical challenges related to high-pressure sealing, corrosion resistance, precision machining, and deep-water wet electrical connections, the company succeeded in developing China’s first domestically produced 1500-meter underwater wellhead production tree. This achievement marks China’s possession of the core technical capabilities needed for the research, development, manufacturing, and testing of such underwater wellhead production trees
