地面测试高压远程控制技术及应用实践
|
摘要
高压含硫气井试油作业期间,地面测试操作人员必须在高压、含H2S区域中工作,一旦发生流体泄漏,操作人员将面临较大的高压伤害和H2S中毒风险。另外,阀门在高压差环境下存在开关困难,操作速度慢,节流控制难度大等诸多问题。"地面测试高压远程控制技术"可以实现远程操作地面流程高压设备,大大降低操作人员在高压含硫区域工作面临的安全风险和劳动强度,同时也可实现自动控压,提高地面测试作业效率和操作准确性。通过现场ST3等多口井中的成功使用,有效达到预期作业效果,提高了作业效率,提升了作业水平。
During testing in the high pressure sulfur contained gas wells,in case of fluid leakage,the operators will face high pressure damage and hydrogen sulfide poisoning. In addition,under high differential pressures,it is difficult and slow to close the test valves,difficult for throttle control. High-pressure remote-control technology for surface testing can remotely operate the high-pressure surface testing equipments,greatly reducing the operating personnel security risks and labor,and able to realise automatic pressure control,improving the surface testing efficiency and accuracy. It has good effects in applications on wells as ST3 well( 3-Ultra Well),etc.
