摘要

摘要: 封堵性可由封堵前后渗透率变化表征，但页岩具低孔、低渗特征，采用常规稳态渗透率测试方法难以获取准确的渗透率值。为此在大量实践基础上，形成了针对超低渗透页岩的压力脉冲瞬态渗透率测试法，可测试渗透率级别低至1×10^-7 mD。以此理论研制成的页岩封堵模拟评价仪，能准确测试低孔、低渗页岩封堵前后渗透率变化，基本解决了页岩封堵测试难题，为评价页岩井壁稳定性及大规模开发页岩气提供技术支撑。

Abstract: Sealability can be characterized by the change of permeability before and after sealing. As to shales, their permeability is diffcult to measure accurately using regular static permeability measuring methods because of the low porosity and low permeability characteristics of shales. Based on plenty of permeability measuring practices, a method of measuring the permeability of shales with ultra-low permeability was proposed. This method, the so-called transient pressure pulse method, is able to measure permeability to 1×10^-7 mD. A shale sealability simulation evaluation instrument has been developed based on the transient pressure pulse method. This instrument is able to accurately measure the change of permeability before and after a low porosity low permeability shale is flooded and sealed. The application of the instrument has to some extent resolved the problem of measuring the permeability of sealed shales, providing technical support to evaluating the shale stability of a well and to the large-scale of shale gas development.
