目前模拟井大多只能起到观摩效果，无法满足三级井控演习要求。本文综合考虑了模拟井普遍存在的井喷时间短，无法实现持续井喷，以及气体与钻井液混合不均匀，井喷效果不理想等问题，设计一种模拟井特制井口装置，同时注水注气模拟井喷场景。应用结果表明，该模拟井能够实现持续井喷，效果良好，经济适用适合推广应用。

 At present, most of the simulated wells can only serve as observation effects and can not meet the requirements of third-level well control exercises. In this paper, considering the common well injection time is short, it is impossible to achieve continuous well injection, the mixing of gas and drilling fluid is uneven, and the blowout effect is not ideal, a special well head device  for simulated well is designed, and water injection is used to simulate the well blowout scene. The application results show that the simulated well can achieve continuous well blowout and has good effect.
