随着社会工业化进程的不断提高,越来越多的油气资源被需要,然而常规勘探的油气资源也越来越不能满足发展的需求,低阻油层作为一种非常规油层也就显得尤为重要。但是由于其成因类型复杂,测井响应分辨率低,导致很难识别它们,因而,对有效识别低阻油层方法的研究与探索将是我们不懈的追求。本文结合近年来国内外对低阻油层的实践经验、研究结果与探索创新,将一些识别与评价低阻油层新的方法、模型、技术进行探讨,本文主要介绍了高分辨率SHARPLite*方法、“双水模型”、电缆地层测试(WFT)—MDT测井技术、可动水分析法(模型)、核磁共振测井以及Thomas-Stieber交绘图。
With the progress of social industrialization, more and more oil and gas resources are needed. However, the conventional oil and gas exploration resources are also less and less able to meet the needs of development. Low-resistivity oil reservoirs, as an unconventional oil layer, are also of particular importance. However, due to its complex genetic type and low resolution of well logging response, it is hard to identify them. Therefore, it is our unrelenting pursuit to research and explore effectively the method of low resistivity reservoir. Based on the practical experiences, research results and exploration innovations of low resistivity reservoirs at home and abroad in recent years, this paper discusses some new methods, models and techniques for identifying and evaluating low resistivity reservoirs. This paper mainly introduces the high resolution SHARPLite * method, “Dual Water Model”, Cable Formation Testing (WFT) -MDT Logging Technology, Movable Water Analysis (Model), NMR Logging, and Thomas-Stieber Crossplot.
