<p>In the process of temporary blocking oil/casing construction using traditional mechanical and hydraulic tools, problems such as low success rates, high accident rates, and low operational efficiency exist. This study designs an electric control servo catching tool. The tool is described in detail from the perspectives of mechanical structure, power system, electric control and debugging system, micro-hydraulic servo system, and execution system. Based on this, the study also explores the design of the process tubing structure and the field construction process, and conducts research on pressurized electric control temporary blocking technology. The aim is to improve the success rate of oil/casing temporary blocking operations and reduce accident rates. The research shows that the electric control servo catching tool consists of two main parts: the deployment and sealing assembly and the catching assembly. The deployment assembly mainly consists of the power system, electric control and debugging system, micro-hydraulic servo system, and execution mechanisms. The application of the electric control servo catching tool in the pressurized electric control temporary blocking process requires a highly reliable and precisely designed process tubing. The structure of the tubing must fully consider multiple factors and use high-strength, high-temperature resistant, and corrosion-resistant materials to ensure that no failure occurs during operations in extreme environments.</p>
