浅析葡西油田凝析气藏地质成因及分布规律

Analysis of Geological Genesis and Distribution Rules of Condensate Gas Reservoir in Puxi Gas-field

针对葡西油田原油性质差异较大的特点,对油气藏类型进行了判断,并在确定为凝析气藏的基础上,通过开展油源对比、油气运聚史及断层发育史等研究工作,揭示了葡西油田葡萄花油层凝析气藏分布规律以及地质成因,并预测了储量规模,为确定油藏的开发方式及油田的大面积开发奠定基础。

In consideration of different characteristics of crude oil in Puxi Oilfield,oil and gas reservoir types were identified.Based on its identification as condensate gas reservoir,through oil source correlation,the oil and gas migration and accumulation history and fault development history and other research work,the distribution and geological genesis of condensate gas reservoir in Putaohua reservoir of Puxi Oilfield are revealed,its reserves scale is predicted,it provides a basis for determining reservoir development modes and oil field development at a large scale.
