摘要
根据弹性力学原理，计算了固井施工作业后浮鞋、浮箍失灵需井口施压时套管和水泥环界面（即第一界面）的微间隙。计算结果和现场试验均表明，大庆地区调整井固井后井口施压高于平衡压力２．０～３．
The microannulus between casing and cement shealth upon well head back pressure after cementing was calculated,based on elastic dynamics.Both calculation and field experiment results have shown that the back pressure of 2 0 to 3 0 MPa higher than balance pressure has no effects on acoustic logging results of the cement.
