低渗特低渗砂岩储层流体识别技术研究综述和展望

低渗、特低渗储层是国内外油田地质研究的重点，而其流体识别问题更是一个焦点问题.本文根据以往的研究成果，再认识了低渗、特低渗储层流体识别的难点，进而梳理和归纳了流体识别的常规技术和新技术.研究表明，利用单一的测井解释方法容易引起多解性，技术风险高；基于地区地质、岩心、录井等资料，结合多种测井曲线，开展流体的综合识别评价是一个重要的技术思路；将现代地质数学方法和信号分析技术引入流体识别中将会产生积极地意义，本文对此进行了展望.

Review and forecast of technique research on fluid identification of low and particularly low permeability sandstone reservoir

Low permeability reservoir is the focus of geological studies at home and abroad, and its fluid recognition is a more focal point. In this paper, the fluid identification difficulties of the stage are presented, and then the conventional and new technologies of fluid identification are summarized. Studies have shown that using a single log interpretation method has usually ambiguity. And then, technical risk is high. Therefore, the combination of regional geological, rock core and well logging data research, based on a number of log curves, multi-identifiable information to carry out a comprehensive identification of fluid evaluation is an important technical method, and the introduction of modern mathematical methods of geological fluid identification and signal analysis technique will have a positive meaning.In this article this is prospected.
