Results of introduction of innovative technology of casing of wells at Kazakhstan oil fields

Authors: S.E. Chernyshov, N.I. Krysin, A.A. Kunitskikh (Perm National Research Polytechnic University, RF, Perm)

Key words: technology of casing, producing well, cement slurries, spacers, durability of casing, improve the quality of oil wells casing.

To improve the quality of oil wells casing requires the fulfillment of a complex of measures, aimed at the preparation of the well bore to the cementing jobs, at the preparation of cement slurries with the required technological properties, at the realization of the mode of spacer and cement squeezing grout injection, at the ensuring the safety of a cement stone and etc. A comprehensive approach taking into account the geological features of the oilfields allows effectively solve the task of improving the quality of the oil wells casing.
