这种方法里，在气缸与缸套之间形成环形间隙，并将其与蒸汽供应相连。
These are fitted into the annular space between the cylinder and the cylinder liner, and are connected to the steam supply.
若按照常规下套管后再注水泥，由于环形间隙小，施工难度大，难以保证固井质量。
It is difficult to guarantee the cementing quantity when using conventional cementing because narrow annulus between casings.
无接箍式套管靠管体两端的螺纹连接，所以套管外径尺寸小，可增大环形间隙，便于套管下入和提高固井质量。
It connects with threads on both ends of pipe body, which allows a smaller casing O. D. and increases annular gap to facility casing running in and improve cementing quality.
