Gas-liquid washover mixtures for well completion in conditions of abnormally low formation pressure

Authors: M.V.Turitsyna (National Mineral Resources University, RF, Saint-Petersburg), E.V. Chernobrovin (Moscow Branch of LUKOIL Overseas Service BV, RF, Moscow), V.A. Morozov (RITEK JSC, RF, Kogalym), G.Yu. Teleev (Techinformservice OOO, RF, Izhevsk), A.V. Kovalev (National Research Tomsk Polytechnic University, RF, Tomsk), E.P. Ryabokon (Perm National Research Polytechnic University, RF, Perm)

Key words: producing well, grouting mortar, gas-liquid mixture, well completion, oil recovery troubles.

The article discusses the necessity of a comprehensive approach to the problem of preservation of reservoir properties of productive beds, providing prevention of bottom zone pollution at all stages of well completion. The article gives the results of studies of the basic technological properties of liquid mixtures for the opening of productive horizons with abnormally low reservoir pressures. The choice of builders and stabilizers for the preparation of gas-liquid mixtures is substantiated.
