WELL TEST INTERPRETATION METHOD OF GAS CONDENSATE WELLS WITH FORMATION PARTLY PERFORATED

The seepage equation of condensate oil and gas was linearization with the introduce of two-phase pseudotime-pressure function of condensate gas. Arm at the flow character of partly perforation in condensate gas well, the test theoretical model was erected, well test typical curve graph was drawn, calculation formula was obtained. Formation capacity, as well as gas well pseudo-skin factor, storage factor of hole and others relate parameter were interpreted basely on pressure build-up data and relative permeability of the gas condensate field.
