Tight gas wells are generally characterized by low porosity,low permeability and high water saturation.In addition,the narrow flow channels for gas and water,the strong filtrational resistance and the larger superficial tension of both liquid-solid and liquid-gas interfaces may result in an obvious increase of water locking effect and stress sensitivity.Water locking effect may damage greatly the tight gas wells and prevent them from high productivity.Therefore,it is significant to study the water locking damage...

Tight gas wells are generally characterized by low porosity,low permeability and high water saturation.In addition,the narrow flow channels for gas and water,the strong filtrational resistance and the larger superficial tension of both liquid-solid and liquid-gas interfaces may result in an obvious increase of water locking effect and stress sensitivity.Water locking effect may damage greatly the tight gas wells and prevent them from high productivity.Therefore,it is significant to study the water locking damage of near-wellbore formation in tight gas wells in order to increase their productivity.On the basis of the principles of the gas flow,the compressional expansion and the evaporative effect which occurs at water-bearing pores saturating gas to remove the water locking damage,we establish the numerical simulation to remove the water locking damage in near-wellbore formations and study the numerical simulation of tight gas wells.

致密气井普遍具有低孔、低渗、高含水饱和度的特点。气、水赖以流动的通道很窄,渗流阻力很大,液、固界面及液、气界面的表面张力较大,使水锁效应和应力敏感性明显增强。而水锁效应对致密气井产生严重伤害,严重阻碍致密气井的产能,因此,研究致密气井近井地层水锁伤害,对提高致密气井产能具有重要意义。文中利用气体的流动、压缩膨胀性,在含水孔隙岩石饱和有压缩性气体时,发生蒸发效应解除致密气井近井地层水锁伤害的原理,建立了近井地层水锁伤害解除数值模型,并对致密气井进行了数值模拟研究。
