摘要
压力脉冲法是一种较成熟的测定低渗致密岩石渗透率的一种非稳态方法,与传统的稳态法相比不需要达到稳定流动状态,具有测量时间短,压力监测易于实现等优点。该论文针对脉冲法渗透率计算方法进行研究,在此基础上明确了每种方法的适用范围。
Pressure pulse method is a well-developed unsteady state way of measuring low-permeability rock.Compare with steady-state technique it has no need to achieve steady-flow and also have the advantages of short measuring time and accurate pressure monitoring.The article mainly introduced the way of computing the permeability and determined the range of application of each method.
