摘要： A method of cementing a wellbore penetrating a subterranean formation comprises blending a base cement slurry with one or more liquid additives to provide a cementing composition, the base cement slurry comprising a liquid carrier, a class G cement or a blend of class G and class C cements as defined by the American Petroleum Institute (API) Specification 10A standards (R2015), and silica fume, or fumed silica, or a combination of silica fume and fumed silica, the base cement slurry having a density of about 14 to about 16 ppg; and injecting the cementing composition into the wellbore. The single base cement slurry can be used globally to make cementing compositions having wide ranges of density and temperature stability.

摘要： A zone isolation cementing system includes a tubular having a longitudinal axis and a first flow-controlled port, a first conduit having a first end and a second end, the first end fluidically connected to the first flow-controlled port, a first distributor manifold arranged to deliver cement slurry exteriorly of the tubular, the second end of the first conduit fluidically connected to the first distributor manifold, and a first settable packer disposed exteriorly of the tubular and arranged longitudinally between the first flow-controlled port and the first distributor manifold.
