The Casing And Cementing Process

  • What Is The Cementing Process?

    2021-4-27 · 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.Casing and Cementing SPE,Casing loads result from running the casing, cementing the casing, subsequent drilling operations, production and well workover operations. Temperature changes and resulting thermal expansion loads are induced in casing by drilling, production, and workovers, and these loads might cause buckling (bending stress) loads in uncemented intervals.
