摘　　要：对于渗透率低于10^(-5)μm^2的储油气层,传统的常规测试渗透率的方法和模型存在一定的局限性。本文叙述了利用瞬时脉冲技术研制的一种新的测试渗透率的仪器,该仪器的密封压力可达60.0MPa,孔隙压力10.0MPa～20.0MPa,可测量范围10^(-8)μm^2～10^(-9)μm^2,重复性±0.08,大部分实验过程和数据采集利用微机,该仪器与美国岩心公司进口的气体渗透率测试仪对比结果符合较好。Tranditional methods and models of measuriag permeability for Low—Permeabilty (<10^(-5)μm^2) reservoir are Inadequate.This Paper des-cribs that a New measuring Permeability instrument is developed usingtransient pulse teehnique.This Permeameter has confining pressure 60.0MPa,pore pressure 10.0MPa—20.0MPa,measuring region 10^(-3)μm^2—10^(-9)μm^2,andthe repeativeness ±0.08.Almost experiment control and data—acquistionfunctoin are performed by a microcomputer,The Instrument is in good agree-ment with importing trandition permeameter for gas from U·S·A.
