In this paper, the structure of the fixed subrings of a class G θ-group ring is studied. The properties about the finite block theory and chain conditions of such fixed subrings are also discussed.

So critical temperature of strength decline, optimum amount of sand added to cement slurry, rule of properly controlling slurry properties and properly choosing additives are determined for Jiahua Class G Oilwell Cement.

从而达到实现确立嘉华G级油井水泥的强度衰退临界温度及合理加砂量、浆体性能的合理调控原则及外加剂的合理选配等目的。
