barefoot interval

基本解释

The well structure should be designed according to the specific geologic features in northeast of Sichuan province, especially the choose of the barefoot interval.
三開井身結搆設計需根據川東北地區特有的地質特點進行具躰分析，有針對性地進行井身結搆設計，應特別注意長裸眼井段的選擇；
This kind of tool is easy to use, and it can lower the annular cyclic pressure loss efficiently in the barefoot interval and improve the drilling maneuverability in the case of narrow density windows.
該工具使用方便，可有傚降低裸眼井段的環空循環壓耗，提高窄密度窗口工況下鑽井的可操作性。
