摘要:
利用气相色谱法对高探1井分离气和分离油进行了油气组成分析。开展高探1井地面原油特性研究,并运用高温高压地层原油分析仪对高探1井地层流体高压物性特征进行了深入研究。结果表明,高探1井地层流体中C1—C5组分含量达71.41%,轻质烃含量较高,重质成分含量低,含蜡量中等、密度低、黏度低、凝固点中等,具有挥发性油的特征。地层原油在地层条件下为单相液态流体,地层异常高压,地饱压差大,地层能量充足,地层油体积收缩率较高,弹性能量较强。结合地层流体高压物性数据,利用储集层流体三元组成三角图、油气藏判别参数(φ1)综合判断,初步认为高探1井的油藏类型为低饱和挥发性油藏。
Abstract:
Hydrocarbon compositions of the separated gas and oil from the Well Gaotan-1 are analyzed by using gas chromatography. The features of the surface oil from the Well Gaotan-1 is studied and in-depth research is carried out for formation fluid physical properties with PVT experimental instrument. The results show that for the formation fluids in the Well Gaotan-1, the content of C1—C5 components reach 71.41%, the content of light hydrocarbons is relatively high, the content of heavy components is low, the wax content and freezing point are medium, the density and viscosity are low, indicating characteristics of volatile oil. The crude oil is single-phase liquid under the formation conditions, the formation pressure is abnormally high, the difference between formation pressure and saturated pressure is large, the formation has sufficient energy, the shrinkage rate of the formation oil is relatively high and the elastic energy is relatively strong. Combining with the PVT data of the formation fluid and using a triangle chart of three elements in reservoir fluid and reservoir identification parameters (φ1), the paper considers that the reservoir in the Well Gaotan-1 is a low-saturation volatile oil reservoir
