Pressure Transmission Efficiency and Changing Pattern of Hydrostatic Pressure of Cement Slurries

open access: yesZuanjingye yu wanjingye
The decline of the hydrostatic pressure of a cement slurry is considered to be one of the main causes resulting in early annular gas channeling, and annular gas channeling in turn is a key factor hindering normal oil and gas production.
