    摘要:

    鄂尔多斯盆地中东部石炭纪本溪组致密砂岩粒度较细,泥质含量较高,孔隙度低、渗透率极差,使测井对其含气性的解释难度增大。基于化验分析资料,重点应用核磁共振、阵列声波、阵列感应等成像测井资料,结合常规测井,建立了4类7种方法的本溪组细粒致密砂岩储层含气性测井评价方法研究,利用测井资料综合开展储层含气性的有效识别。研究表明,综合运用常规和成像测井,对本溪组细粒致密砂岩储层含气性综合评价提供了更加有效的途径。开展本溪组细粒致密砂岩储层含气性测井综合评价研究,对煤系致密砂岩气的勘探和开发具有重要的理论意义和应用价值

    Abstract:

    The thick tight sandstone reservoir of Carboniferous Benxi Formation is developed in the middle and eastern Ordos Basin. However, due to its fine lithology, high mud content, low porosity, poor permeability and complex pore structure, it becomes more difficult to interpret the gas bearing property by logging. Research on the basis of the analysis and drilling practice, focus on application of nuclear magnetic resonance (NMR), acoustic array, array induction imaging logging data, combined with the conventional logging, 4 kinds of 7 kinds of methods, set up comprehensive Benxi Formation of fine particle tight sandstone hydrocarbon reservoir logging evaluation method study, using the comprehensive logging data for reservoir hydrocarbon content of effective recognition. The study shows that the comprehensive application of conventional and imaging logging provides a more effective way for the comprehensive evaluation of gas bearing capacity of fine tight sandstone reservoir in Benxi Formation. It is of great theoretical significance and application value to study the comprehensive evaluation method of gas bearing property of fine grained tight sandstone reservoir in Benxi Formation.
