【摘要】 结合油田深井井下仿真环境系统的研制，对超深井钻采设备环境仿真系统设计进行了讨论。环境仿真系统采用物理模拟及半实物仿真等多种手段，实现了不同地质条件、不同井深的井下环境的仿真。并在大型超高压容器制造、超高压液压系统的设计、多介质大延时非线性控制系统设计、仿真环境中试验设备工作状态的检测、油井井下环境的建模等方面取得了新的突破。更多还原

【Abstract】 Design of an environment simulation system (ESS) for drilling & culling devices working in ultradeep well is discussed in this paper, on the basis of developing an in-well environment simulation system for deep well of oil field. The ESS adopts multi-means such as physical simulation and half-real object simulation and can be used to simulate in-well environment of various geologic and various depth well. New breakthroughs are obtained in manufacturing large-scale ultrahigh pressure container, design of ultrahigh hydraulic pressure system, design of multi-media large delay nonlinear control system, detecting state of device tested under simulation environment, modeling of in-well environment of oil field.更多还原
