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。
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 experimental study on the relationship between annulus pressure differential, interlayer differential and cementing quality is carried out on the lab simulation test unit.
室内利用模拟试验装置进行了环空压差和层间压差与固井质量的关系的试验研究。
