barefoot interval

基本解釋

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(jié)構(gòu)設計需根據(jù)川東北地區(qū)特有的地質(zhì)特點進行具體分析，有針對性地進行井身結(jié)構(gòu)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，可有效降低裸眼井段的環(huán)空循環(huán)壓耗，提高窄密度窗口工況下鉆井的可操作性。
