摘要
完井负压装置是针对自喷能力的井设计的一种能够在地面控制压差的装置,具有结构简单、适应性强的特点,能根据需要选取诱喷压差,具备井下测试阀部分功能,适用于气层完井试采作业,一趟管柱完成负压射孔、诱喷和放喷求产等多项作业,不用测试阀、不借助气举等自造负压,大大节省了作业成本,缩短了作业时间,提高了作业安全性。
Negative pressure device of the completion well is designed for wells having flowing capabilities whose pressure is controlled at ground,which has features of simple structure and good adaptability and selects differential pressure for induced flow according to needed.It has function of down hole test valve to suit for completion and oil test operation to gas layers,by which fulfils many jobs of under balanced perforating,induced release spray jet production with one trip,self-made negative pressure without tested valve and without the aid of gas lift,which saves operating costs significantly,shortens operating time and improves the operating safety.
