|
摘要
为研究节流阀在实施压井节流时的可靠性和耐冲蚀性能,采用有限元仿真分析和试验相结合的方法,对新型筒式节流阀、楔形节流阀和孔板节流阀的冲蚀性能进行了对比研究。研究结果表明,泥浆密度1.8 g/cm~3,冲蚀时间8 h。新型筒式节流阀相对于楔形节流阀、孔板节流阀具有更好的抗冲蚀能力、可靠性高,能够满足井控工艺的要求。
In order to study the reliability and erosion resistance of throttle valves in killing wells, the erosion performance of new type tubular throttle valves, wedge throttle valves and orifice throttle valves were compared by using the method of finite element simulation analysis and experiments. The results show that the new tubular throttle valve, which has better erosion resistance and reliability than the wedge throttle valve and orifice plate throttle valve, with the mud density of 1.8 g/cm~3 and erosion time of 8 hours can fulfill the requirements of well control performance.
