气体润湿性评价方法综述
|
摘要
理论和实验证实凝析气藏多孔介质表面润湿性由液湿性转变为优先气湿可显著提高气井产量,且气湿程度对气井产量影响较大。但是由于气体具有较强的压缩性,传统的液湿性定量评价方法((USBM法和Amott法))不适用于气体润湿性评价。通过理论分析和润湿性实验研究,整理并提出了气体润湿性评价的新方法:停滴法、气泡捕获法、表面能法、毛细管上升法。首次提出应用停滴法和气泡捕获法分别建立了气湿性定量评价的方法,确立了气湿性定量评价指标,为气湿性理论研究奠定了基础。
Theoretical analyses and experimental results show that if the surface wettability of the porous media transfer from liquid-wetting to prior gas-wetting,the yield of the gas well can dramaticlly increase,and the degree of the gas-wetness also strongly affects the gas deliverability.However,for the reason that the gas has a strong ability of compressibility,the traditional liquid-wetting quantitative evaluation methods(USBM method & Amott method)does not apply to gas-wetting evaluation.A new gas-wetting evaluation method is concluded and established on the basis of theoretical analyses and the experimental researches on the wettability: the sessile drop,the captive bubble,the surface energy,and the capillary tube rise.The research group first proposed the gas-wetting quantitative evaluation methods which are established on methods of the sessile drop and the captive bubble,confirmed the gas-wetting quantitative evaluation index,laying a solid foundation for the gas-wetting theoretical research.
