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.
井底环空压力是小井眼钻井的关键参数，通常的压力降计算方法对小井眼不适用。
Experimental and theoretical research has improved that hole cleaning detecting is efficient by monitoring annular pressure change.
研究表明，利用环空压力变化可以有效监测井眼清洁程度。
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.
该仪器采用TMS320LF2407A为总控制器，能够实时测量，存储钻压、扭矩、环空压力和侧向力等4项钻进参数。
