摘　　要：岩石气体渗透率是油田勘探开发最重要的基础数据之一。文章介绍了国内外岩石渗透率测试气体流量计量技术的现状 ,针对低渗透储层油气藏勘探开发过程中岩石渗透率测试存在的问题 ,开发研制了一套节流毛细管气体流量计量自动测定装置 ,建立了岩石渗透率节流毛细管 p -q回归测试方法。该测试方法计量气体通过岩石的能力速度快 ,测试精度高 ,自动化程度高 。Rock gas permeability is one of the most important essential parameters in the oil field exploration and development. In this paper the present technical status of rock permeability testing technique on gas flow measurement at home and abroad is introduced. Aiming at the open question of rock permeability measurement in the exploration and development course of hydrocarbon reservoir of low permeability, we have worked out a suite of automatic metering device of throttling capillary gas flow, and set up throttling capillary p-q regression testing approach of rock permeability. This approch, which is swift in measuring the ability of gas passing through rock, and of high measuring accuracy, is a great breakthrough in measuring and testing techniques of rock permeability.
