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。
So it is recommended that the pressure differential between the casing and the annulus be increased to improve the cementing quality if the downhole conditions permit.
建议在井下条件允许的情况下,增加环空与套管内的压差值来提高固井质量。
