A small gap that can form between the casing or liner and the surrounding cement sheath, most commonly formed by variations in temperature or pressure during or after the cementing process.

在套管或衬管与周围的水泥环之间所形成的小间隙，这些间隙是由于在固井期间或固井之后温度或压力的变化所致。

Squeeze cementing USES pressure to force the cement through holes or perforations in the casing.

挤水泥时在压力下将水泥浆压经套管中的射孔孔眼。

The casing tectonic stress load defined by elastic solution is slightly less than the maximum pressure subjected by casing pipe in rheological formation.

用套管弹性解定义的套管地应力载荷，稍低于流变地层中套管所受最大压力。
