超深稠油螺杆泵举升工艺技术研究与应用

针对鲁克沁油田超深稠油油藏特点,在分析前期井筒举升工艺的基础上,采用螺杆泵配套环空掺稀油降粘井筒举升工艺,成功将稠油举升到地面,达到了增大油井生产压差、提高产量的目的。初步形成了稠油冷采螺杆泵深抽配套工艺技术,该技术为鲁克沁超深稠油油田采用螺杆泵开采奠定了基础,具有推广应用前景。

Study and Application on Technology of Ultra-Deep Heavy Oil Lift by Screw Pump

Aiming at the feature of heavy oil reservoir in Lukqin oil field,after system analyzed of prophase shaft body lift technology,screw pump was used with lift shaft body technology matching the annulus of oil string and casing mix into light oil in order to reduce oil viscosity,which was first successfully applied with screw pump successfully lifting heavy oil to ground and reached the aim at increasing pressure difference in production of oil well and improve output.At the same time in the research and practi...
