摘要： The present disclosure provides an ultra-high temperature resistant cement slurry system for cementing and the preparation method and use thereof. The cement slurry system comprises cement, an ultra-high temperature strength stabilizer, an ultra-high temperature reinforcing material, a density regulator, an ultra-high temperature suspension stabilizer, a dispersant, a fluid loss additive, a retarder, a defoaming agent and water, wherein the ultra-high temperature suspension stabilizer comprises an ether-based starch, an aluminosilicate and a polyalcohol polymer. The method for preparing the cement slurry system includes dry mixing and wet mixing raw materials homogeneously, respectively, and then homogeneously mixing the dry mix and wet mix to obtain the cement slurry system. The present disclosure further provides use of the cement slurry system for cementing in deep wells and ultra-deep wells at high and ultra-high temperatures. The ultra-high temperature resistant cement slurry system for cementing provided by the present disclosure has a strong temperature resistance, a wide applicable range, and an excellent settlement stability. It can prevent the decline of strength of cement stone at high temperature, ensure the cementing and sealing effect and improve the cementing quality.

摘要： The effectiveness of expansive cement systems may be diluted when, during a well cementing operation, commingling takes place between the cement slurry and a spacer fluid, a drilling fluid, or both. Incorporating expansive agents in the spacer fluid or drilling fluid may reduce or negate the loss of expansion at the cement slurry/spacer interface or the cement slurry/drilling fluid interface, thereby promoting zonal isolation throughout the cemented interval.

摘要： A formulation containing polymer, resin and cement combined with aggregate can be used as a gunnable mix that is applied to a surface by being conveyed pneumatically in dry form to a nozzle, where water is added. Polymer in the gunnable mix enables it to adhere and bond to a surface, such as carbon brick, of a lining of a vessel used for the containment of molten metals. The formulation may be used, for example, to repair and protect blast furnace hearth linings.
