过饱和水汽压缩系数对比和水化分子——纯气井静气柱性质的进一步讨论

SUPERSATURATED STEAM, COMPARISION OF COMPACTING FACTOR AND HYDRATED MOLEC ULE

以前已经讨论了混合天然气体摩尔组成、压缩系数沿井筒分布的规律,根据这些规律进一步对天然气井中水蒸汽、天然气的压缩系数差异等性质进行更深入的分析研究。从而揭示纯天然气井静气柱中存在着复杂的分子缔合现象,分子缔合后形成水化分子,使井筒内的天然气与实验室中天然气气体性质出现较大差异。

On the basis of the molar composition of mixing natural gas and the distribution law of compacting factor in wellbore, the paper analyzed the discrepancy of compacting factor between steam and gas in natural gas well, thus showed that the complex molecular association appearance exists in static gas column in net gas well. After molecular associated, the hydration molecule was formed. It follows that the property of gas has great discrepancy in wellbore and in laboratory.
