Abstract: To address the issues of over-reliance on imported core tools for intelligent testing and insufficient independent technological controllability in deepwater/superdeepwater oil and gas exploration, the research and development of an intelligent testing and circulation valve tool for deepwater/superdeepwater was carried out. This tool integrates dual functions of circulation control and test control, and can adapt to the operational requirements under complex deep-water well conditions. The paper focuses on two core links: tool design and testing. In the design phase, the overall structural scheme planning and detailed design of key components such as the circulation valve, test valve, air chamber, hydraulic chamber, and electro-hydraulic bridge were completed. The motion coordination was verified through dimensional chain calculation, and the structural stability of components under extreme environments was ensured by combining strength check and finite element analysis. In the test phase, seven sets of special test platforms were built in accordance with industry standards, and systematic tests were conducted on sealing performance, strength characteristics, operational reliability, and electro-hydraulic cooperative control performance. The results show that each component of the tool has good sealing performance and timely action response, and the overall performance meets the requirements of deepwater/superdeepwater oil and gas well testing operations, providing technical support for the localization of marine deep-water intelligent testing equipment.
