摘要  渗透率是十分重要而又难以准确计算的储层参数之一。目前渗透率测井评价主要依据4 类方法,即:基于孔渗关系的渗透率评价、基于核磁共振测井的渗透率评价、基于斯通利波测量的渗透率评价以及基于大数据和人工智能的渗透率评价。通过对上述方法适用性的分析发现,井筒斯通利波与储层孔隙空间流体的流动性密切相关,在储层渗透率评价中具有明显优势。但目前渗透率测井评价面临艰巨挑战,其原因包括3 个方面,即:确定渗透率参数本身的理论、实验难度,评价对象复杂性的日益增大和尚未形成能用于井下连续测量渗透率的装备。本文指出,推进斯通利波渗透率评价理论、方法和技术研究,构建新的以斯通利波测量为核心的渗透率评价技术体系是新一代测井技术发展的方向。

Abstract

Permeability is one of the important and difficult to accurately calculate reservoir parameters. At present, the evaluation of permeability logging mainly has four types of methods, namely: permeability evaluation based on porosity-permeability relationship, permeability evaluation based on nuclear magnetic resonance logging, permeability evaluation based on Stoneley wave measurement, and permeability evaluation based on big data and artificial intelligence. Through the analysis of the applicability of the above methods, it was found that the wellbore Stoneley wave is closely related to the fluidity of fluid in the reservoir pore space and has a significant advantage in permeability evaluation. However, at present the permeability logging evaluation faces great challenges due to three reasons: the theoretical and experimental difficulty of determining permeability parameters themselves, the increasing complexity of evaluation objects, and the lack of equipment that can be used for continuous permeability measurement underground. This article points out that promoting the research on the theory, methods, and techniques of Stoneley wave permeability evaluation and constructing a new permeability evaluation technology system centered on Stoneley wave measurement is the development direction of the new generation logging technology.
