Well Cementing Method for Improving Well Cementing Quality by Controlling Hydration Heat of Cement Slurry

A well cementing method for improving cementing quality by controlling the hydration heat of cement slurry, wherein

• by controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section;
• wherein the cementing quality at the open hole section is improved by increasing the degree and/or rate of hydration heat release from cement slurry;
• and
• the cementing quality at the overlap section is improved by lowering the degree and/or rate of hydration heat release from cement slurry.
