Field Application of Low Density Fly Ash Cement
-
Abstract
Fly ash,characterized by small grain size and great fineness,is a kind of blast furnace ash.It can lower the gravity of cement slurry when mixed with cement.Laboratory experiment and field application show that it can meet the requirements of well cementing in easy- to - leak formations under low temperature and pressure in respect of strength, leakage resistance and corrosion resistance etc.
