摘要

Based on a three-phase multicomponent filtration model, the possibilities of efficient exploitation of the oil rim of a gas condensate formation by a horizontal well with a gas-free production rate were investigated. It was found that the regime of critical gas-free production rates, as applied to horizontal wells, allows one to avoid a breakthrough of the gas and water cones and, by adjusting the distance between wells and their initial oil flow rates, to significantly increase the final oil recovery factor.
