Utilizing perforated device by under-balance pressure to create new operating mode,on condition of outer power to induce flow without lowering testing valve and gas lift,many operations of under-balance perforating,induced flow and production with open flow by one set of testing string have been realized by man made negative pressure,that shortens operating time,lows cost,and raises safety.
采用负压开孔装置建立新型作业模式,在不下测试阀、不借助气举等外力诱喷条件下,自造负压实现一趟管柱完成负压射孔、诱喷和放喷求产等多项作业,缩短了作业时间,节省了作业成本,提高了作业的安全性。
In order to solve this problem,the auto-jet inducing ventilation system i.
为解决好这两者之间的矛盾,笔者将喷流诱导通风引入地下复式汽车库的机械通风系统设计中,并从工程造价、施工方法、节省能源、空气品质等几方面对喷流诱导机械通风系统与传统通风、排烟合用系统进行比较。
