摘要
通过仪器模拟地层高压,在高压条件下进行单相和一定含水饱和度下天然气渗流实验,提高了实验研究的真实性。研究获得:在高压条件下,无论是单相气体,还是在一定含水饱和度下,气体渗流都存在滑脱现象。通过对比得出了高压条件下渗透率和含水饱和度对渗流速度的影响。同时,在高围压岩石有可能产生压敏效应,从而导致天然气的非达西渗流。
Through the equipment produce high pressure,conducted the gas flow experimental study to single-phase gas and gas with certain water saturation under conditions of high pressure in tight forma- tion,to enhance the authenticity of the experimental study.Research:In the high-pressure conditions, both single-phase gas,or in certain water saturation,there are gas seepage slip phenomenon.By compar- ing the high-pressure conditions that penetration and water saturation of the seepage rate of impact.In- sides,high...
