What Is The Cementing Process?

2021-4-27  2. Cementing. Cement injection is a key process after casing entering the well. Its function is to seal the annular space of the casing and the well wall to seal the oil and gas water layer, so that the casing becomes a passage for oil and gas to pass into the well. 3. Oil well cement
