Oil Well Cementing Properties And Functions Drilling

Feb 25, 2021 The cement used for oil well cementing differs from concrete or masonry work in that it consists of a thin slurry of primarily cement and water. The cement used in oil wells must possess three primary properties. They must possess a proper water-to-cement ratio, a sufficient fluid time to allow placement, and must develop enough strength in a minimum time to bond the pipe to the formation.
