PROCESS FOR PRODUCING NATURAL GAS AND NATURAL GAS CONDENSATE FROM UNDERGROUND GAS CONDENSATE DEPOSITS

摘要

The invention relates to a method for the recovery of natural gas and/or natural gas condensate from a subterranean gas condensate reservoir, which contains a gas mixture having retrograde condensation behavior, said method comprising at least the following method steps: a) sinking at least one production bore into the subterranean gas condensate reservoir and recovering natural gas and/or natural gas condensate from the subterranean production well by means of the at least one production bore; b) injecting a solution (L), which comprises a solvent and urea, through the at least one production bore into the subterranean gas condensate reservoir; c) inserting an idle phase, in which the urea contained in the solution (L) is hydrolyzed; d) recovering natural gas and/or natural gas condensate from the subterranean gas condensate reservoir by the at least one production bore.
