Moreover, the wellbore annulus pressure increased with the increasing of invaded formation water quantity. but the amplitude is not obvious.───此外，井筒环空压力也随着地层水侵入量的增加而增大，但增幅不明显。

Without keeping annulus pressure to static and instead of special metering by simple mechanical pressure ba lance structure, this valve is conducted by annulus pressure.───该阀采用环空外压操作测试阀的开关，不需要保压，而且采用简单的机械压力平衡机构代替了专用计量套。

Based on field investigation and statistical data, the relation plate of annulus pressure differential, interlayer differential and cementing quality is plotted.───结合现场调查和统计规律，建立了环空压差和层间压差与固井质量的关系图版。

The annulus-pressure pulling-rope ignition device exists many problems in TCP perforation or TCP-DST interaction.───环压式激发牵绳点火引爆装置在TCP射孔及TCP+DST两联作技术中存在着许多缺点。
