Development of a hydrocarbon completion system for wells with low bottomhole temperatures for conditions of oil and gas fields in Eastern Siberia

The paper presents the results of investigations on influence low bottomhole temperatures in intervals productive formations technological properties solutions used for drilling and completion wells order to determine possibility increasing gas recovery coefficient at field “Sila Sibiri” pipeline. analysis measures determining quality horizon drilling-in was carried out. It found out that dispersion bridging agent composition hydrocarbon-based mud selected from existing methods does not have significant change depth filtrate penetration into formation conditions temperatures. main reason decrease near-bottomhole zone permeability – increase plastic viscosity medium under A destructor solution efficient wellbore cleaning components developed. laboratory developed solution, as well its pilot tests. mechanism interaction between filter cake ensuring reduction skin factor geological hydrodynamic structure Botuobinsky, Khamakinsky Talakhsky horizons Chayandinskoye oil condensate has been scientifically substantiated.
