摘要： 针对古龙凹陷地区缺乏高压PVT相图的情况,首先通过试油成果中气油比的特征区分出油藏和气藏两种类型,然后在油气配方合成井流物的摩尔组成基础上,借助于φ值法、Z值法和PR状态方程计算PVT相图进行综合分析,判断出古109井区葡萄花油层是一个带油环中等凝析油含量的凝析气藏。根据凝析气藏的成藏机理,预测了该区凝析气藏分布的有利区带。

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.
