annular pressure

基本解釋

Downhole annular pressure is a key parameter. Conventional pressure loss calculation method is not applicable to a slin - hole.
井底環(huán)空壓力是小井眼鉆井的關鍵參數，通常的壓力降計算方法對小井眼不適用。
Experimental and theoretical research has improved that hole cleaning detecting is efficient by monitoring annular pressure change.
研究表明，利用環(huán)空壓力變化可以有效監(jiān)測井眼清潔程度。
The device adopted TMS320LF2407A as main controller. It can determine and record four drilling parameter of drilling pressure, torque, annular pressure and side pressure in the real-time mode.
該儀器采用TMS320LF2407A為總控制器，能夠實時測量，存儲鉆壓、扭矩、環(huán)空壓力和側向力等4項鉆進參數。
