摘　　要：在出砂气藏,支撑剂对其开采有着至关重要的作用,而渗透率又是支撑剂重要性能。石英砂和树脂覆膜砂有着不同渗透率,主要通过室内实验方法研究,分别用气测和液测它们的渗透率。气测时,改变气体的流速,分析不同流速和不同时间对渗透率的影响。液测时,分别在不定轴向压力下改变液体流速,稳定轴向压力下改变液体的流速,分析轴向压力、流速以及不同时间对渗透率的影响。该研究对深入了解油气藏的开发动态和采收率具有一定意义。For Gas reservoirs in the sand,proppant has a vital role of mining,and proppant permeability is an important performance.Quartz sand and resin coated sand have different permeability,which should be tested loy laboratory methods.When we use gas measurement,gas flow rate is changed,so analysis of different flow rates and at different times on the permeability is got.As Liquid is measureed,under pressure the volatile liquid axial velocity is changed,and axial stability of the liquid under pressure affects the flow rate,the axial pressure,flow rate and data of different time are analyzed in terms of permeability.And the study has some significance for the deeper understanding of the dynamic development of oil and gas reservoirs and its recovery.
