Abstract:

Both the testing and production system of the condensate reservoir are influenced by reservoir, wellbore and surface pipeline. At present, the lack of attention on the production effected by retrograde condensation and old techniques used in studying condensate reservoir resulted in irrational testing and work regulations, low and inefficient production. Based on the accurate analysis of the influence on the production of condensate reservoir caused by retrograde condensation, the method for studying condensate reservoir was changed according to the coupling computation model established to the multiphase wellbore pipe - flow and stratum filtering flow, which provides theory support for the testing and single well optimization analysis.
