摘要： 针对火山岩油藏储集层岩性复杂、非均质性强的特点,对火山岩储集层岩石物理学特征进行了综合研究。应用现有测井资料,采用模糊数学方法建立识别火山岩储集层岩性模型;利用双侧向电阻率,在识别裂缝类型基础上,建立裂缝孔隙度解释模型;利用大岩样校正小岩样,与测井解释有效孔隙度建立关系,求取有效孔隙度;根据不同裂缝类型,利用双测向测井资料,建立流体饱和度解释模型。应用实测资料对所建模型进行可行性评价,达到较高的一致性,取得理想效果。

Abstract: In light of complex lithology and serious heterogeneity of volcanic reservoir rock, this paper presents a comprehensive study of petrophysical characteristics of it. By using available well log data and fuzzy mathematical method, a lithologic model for identification of volcanic reservoir is developed. According to recognized fractural types, a model for fractural porosity interpretation is established. By way of correction of small core sample using big sample, relationship between core porosity and effectively estimated well log porosity is built up, obtaining effective porosities. Using different fractural types and dual lateral log data, a model for fluid saturation explanation is set up. Furthermore, these models and measured information are used for feasibility evaluation of them, reaching higher consistency and satisfied results.

Key words: volcanic rock, reservoir, petrophysics, fuzzy mathematics, fractural porosity, effective porosity, saturation
