Improvement of insulating properties of the KF-Zh resin

Authors: T.M. Vakhitov, R.M. Kamaletdinova, L.D. Emaletdinova, T.A. Kargapoltsev (Bashneft-Geoproekt OOO)
The results of the study of liquid industrial lignosulfonates, water-soluble epoxy resins DEG-1, TEG-1, inorganic additive-zeolite NaA and gas-forming compositions, used to reduce shrinkage of KF-Zh resin based oil well cement are presented. Formulations of KF-Zh resin based foamed plugging compositions, recommended for carrying out of insulation works in wells with temperatures above 50 °С, are developed.
