The main directions of improving the quality of well completion in the oil fields and areas of Perm region

Authors: T.V. Krapivina, N.I. Krysin (PermNIPIneft Branch of LUKOIL - Engineering LLC in Perm, RF, Perm), S.E. Chernyshov, A.A. Kunitskikh (Perm National Research Polytechnic University, RF, Perm)

Key words: completion, differential pressure, drawdown, invert emulsion, demulsi tying agent, separation set, shale shaker, centrifuge.

In the cycle of wells construction completion is one of the main and technically complicated processes. The quality of the execution of this stage in the exploratory wells depends largely on the assessment of the perspectiveness of new oil fields and even the district of its location, and in producing wells – production rate.
