水平井分段砾石充填技术及现场应用

Segmented gravel filling technology for horizontal wells and its field application

采用高渗的砾石进行裸眼充填,具有长期保持油井高产、井壁稳定以及防止地层出砂等优点,可有效避免滤砂管的堵塞和磨蚀。

High permeability gravel is used for open-hole filling.It has the advantages of long-term maintenance of high production of oil wells,wellbore stability and prevention of formation sand production.It can effectively avoid blockage and abrasion of sand filter tube.
