摘要
研制了一种气水相对渗透率测量教学实验仪器,用于模拟气水系统下相对渗透率测量的教学实验。该仪器系统包括岩心夹持器、驱替系统、压力系统和计量系统,可提供气水系统下水相渗透率、束缚水饱和度点、等渗点、残余气饱和度点。通过公式还可以计算出任何给定水饱和度条件下的相对渗透率。这套仪器让学生通过易懂可视的结构化步骤学习实验过程,帮助学生理解渗透率测量原理及其在地层评价中的应用,也有助于提升学生的实践动手能力。
An experimental instrument for measuring the relative permeability of gas and water is developed,which is used to simulate the relative permeability measurement.The instrument system includes a core holder,a displacement system,a pressure system and a metering system,which can provide the water phase permeability of the gas water system,irreducible water saturation,residual gas saturation point and isotonic point.The relative permeability of any given water saturation can be calculated by the formula.This instrument allows students to understand the steps of structured visual learning experiment,to help students understand the permeability measurement principle and its application in formation evaluation,but also help to improve students practical ability.
