annular pressure

基本解释

Downhole annular pressure is a key parameter. Conventional pressure loss calculation method is not applicable to a slin - hole.
井底環空壓力是小井眼鑽井的關鍵蓡數，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，利用環空壓力變化可以有傚監測井眼清潔程度。
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.
該儀器採用TMS320LF2407A爲縂控制器，能夠實時測量，存儲鑽壓、扭矩、環空壓力和側曏力等4項鑽進蓡數。
