DISCRIMINATION OF CONDENSATE GAS RESERVOIR AND ITS FAVOURABLE AREA IN GULONG SAG, SONGLIAO BASIN

Abstract

Abstract: Based on gas oil- ratio characteristics of oil testing result, oil reservoir and. gas reservoir were discriminated for lack of PVT data in Gulong sag area. Moreover, on the basis of molar component of wellstream effluent, it is concluded that Putaohua oil-layer in area of Well Gu109 is a condensate gas reservoir with oil ring and medium condensate oil content according to comprehensive analyses of PVT phase diagram calculated by φ and Z value methods and PR state equation. Based on reservoir-forming mechanism of condensate gas reservoir, the favourable distribution area of condensate gas reservoir distribution was predicted.
