| 摘 要： | 理论和实验研究表明,泥质砂岩的激发极化效应与岩石的孔隙结构相关,而且孔隙结构也影响岩石的渗透率,因此泥质砂岩的孔隙结构能够作为一个桥梁,将激发极化效应与渗透率联系起来,从而可以在井下进行激发极化测量,利用测量的参数以及相关导出参数进行渗透率求取.为了更好地研究岩石的激发极化特性,开发相应的渗透率测井仪器,介绍了岩石的时间域和频率域激发极化特性.频域激发极化与比表面积关系密切,但是在工程上较难实现;时域激发极化与孔径分布关系密切,工程上实现相对容易.未来的发展方向应该是在井下测量时域激发极化衰减谱,对其进行反演得到弛豫时间谱和频域激发极化参数,通过这些参数综合求取渗透率.

| Abstract: | Theory and experimental results show that pore structure has important influence on induced polarization(IP) and permeability of shaly sand reservoir.So the pore structure acts as a "bridge" between the IP parameters and its permeability of the core.The IP can be measured downhole and can be used to estimate the permeability.In order to make better research on the IP characteristics of the rock and to develop the IP logging tool to obtain the permeability,the time-domain and frequency IP of the rock have be... |
