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。
The short liner cementing technique can successfully solve some difficult technical problems, such as casing collapse, loss circulation during ultra deep exploratory well drilling operations.
超深探井在钻进过程中出现套管挤毁、井漏而常规封堵无效等复杂问题,影响了下一步正常钻进,短回接尾管固井技术能很好地解决该技术难题。
