Abstract: The high pressure PVT experiment data of Wellblock Hu-2 condensate gas reservoir in Hutubi gas field are calculated. The fluid compositional characteristic parameters used for describing the phase behavior of this reservoir are determined. According to the petrophysical parameters from individual well and layer integrating with structure geometry and well location, a 3D geologic model is developed. Following its reserves matching, study of the gas production history matching is made, obtaining satisfactorily matched results. For demonstrating the technical parameters for reasonable exploitation of Wellblock Hu-2 gas reservoir, the numerical simulation research in nine aspects is conducted. The main conclusions are that seven gas wells can meet the production requirement, and productivity plan of 150x104m3/d is reasonable, with stable production period of eight years ranging from Ian., 2003 to Dec., 2020. It is estimated that recovery percent of natural gas and condensate will reach 70.7558% and 44.1564%, respectively, by the end of 2020.
