苏北地区老井复查测井综合评价技术及方法研究

Restudy of Old Wells:A Study of Comprehensive Assessment Techniques and Methods for Well Logging

随着苏北小油田勘探开发程度的提高,非常规储层日益成为重点勘探开发的对象。苏北地区老井测井资料复查,立足现有的常规测井资料,结合测试等资料,通过扎实的基础工作和测井评价技术和分析方法的进步和提高,重点在"干、密、水、无"中全方位找油,并对以往相对忽视和评价认识手段方法相对不足的低孔渗储层、特殊含灰低孔渗储层与低阻油层作为重点研究分析对象,对测井资料进行全面复查评价,取得了良好的油气成果。

With the promotion of exploration and development of young oilfields in Northern Jiangsu Province, non-conventional reservoir is becoming a focus. Based on the conventional logging and testing data, the aim to find oil under the condition of ＇dry, dense, high water-content and no oil＇ is depend on firm basic work, as well as the progressive assessment techniques and analysis methods. Reservoirs of low-porosity and low-permeability, its special with ash contained and low-resistivity, which are lack of recognition and methods of cognition and assessment in the past, are regarded as key study objects in this study. After introducing it into a comprehensive revision and assessment of the logging data, we achieved a good result on oil-gas.
