智能井流量控制系统高温电磁阀结构优化设计
Optimized Design of High-temperature Solenoid Valve Structure of Intelligent Wells Flow Control System
摘要
Abstract
The downhole flow control system,as the central component of intelligent completion systems,is crucial for intelligent downhole mining.The downhole high-temperature solenoid valve,as a vital component of the electronic-controlled hydraulic drive flow control system,significantly impacts the system's performance.This paper introduces the structure and working principle of the solenoid valve developed an electromagnetic model using finite element simulation,analyzes the effects of static core cone angle,static core protrusion,coil position,magnetic shielding ring inclination,and magnetic shielding ring length on electromagnetic force characteristics,and performes an electromagnetic-thermal coupled simulation analysis.This study uses an orthogonal experimental design to investigate the primary and secondary relationships between electromagnetic force structural parameters,and it optimizes the electromagnet's structural parameters using the optimization concept of combining the response surface method with the improved particle swarm algorithm.Following optimization,the electromagnetic force at 0 mm increases by 16.68%,at 0.5 mm by 29.62%,and at 1 mm by 31.06%.This study provides a theoretical foundation for the design of an electronic-controlled hydraulic drive flow control system.关键词
