High-temperature oil gas well cementing material
The invention discloses a high-temperature oil gas well cementing material, and belongs to the field of oil gas well cementing material. The high-temperature oil gas well cementing material is used for solving problems of the prior art that when conventional well cementing materials are used at high temperature, high temperature strength is low, and durability is poor. The high-temperature oil gas well cementing material comprises, by weight, 40 to 70% of oil well cement, 10 to 50% of metakaolin, 0 to 35% of a silicon material, and 0 to 28% of calcined bauxite. According to a preparation method, a hydration product with an anorthite structure is obtained via reaction of the raw materials above; crystal phase transformation of the hydration product is not caused at high temperature, so that well cementing quality is improved obviously, and well body service life is prolonged.
