摘要/Abstract

摘要： 滨里海盆地石炭系为碳酸盐岩地层,主要发育KT-Ⅰ与 KT-Ⅱ两套含油层系,该区域分析化验资料较少,储层综合分析不全面,储量评估难度大。采用天然岩心,综合运用岩石薄片、高压压汞、孔渗分析等技术手段,对KT-Ⅰ与 KT-Ⅱ层进行岩石学特征分析、储层物性及空间类型分析、储层渗流特征分析。综合分析结果表明：两套含油层系为典型的特低孔、特低渗储层,局部发育微裂缝,孔渗参数变化大,非均质性较强;KT-Ⅰ层渗流通道发育优于KT-Ⅱ层,根据渗流实验结果把两套储层划分为油气水三套系统的不同阶段。依据室内实验数据及测井解释成果进行储层识别与地质储量评估,单位面积（1 km²）地质储量为47.21×10⁴ t,单位面积（1 km²）注水开发可采储量为21.75×10⁴ t。该研究结果可为滨里海盆地石炭系储层油气资源评价及开发方案编制提供指导依据。

Abstract: The Carboniferous system in the Marginal Caspian Basin is a carbonate formation, mainly developings two sets of oil-bearing series, KT-Ⅰand KT-Ⅱ. There is limited analysis and testing data in this area,and the comprehensive analysis of the reservoirs is not systematic,making reserve assessment difficult. In this paper, natural cores, thin sections, high-pressure mercury injection, porosity and permeability analysis and other technical means are comprehensively used to carry out the analysis of petrology characteristics, reservoir physical properties and spatial types, and reservoir seepage characteristics on reservoirs KT-Ⅰ and KT-Ⅱ. The comprehensive analysis results show that two sets of oil-bearing series are typical ultra-low porosity and ultra-low permeability reservoirs, with local micro fractures, large changes in porosity and permeability parameters, and strong heterogeneity. The development of seepage channels in KT-Ⅰ reservoir is better than that in KT-Ⅱ reservoir. Based on the results of seepage experiments, the two sets of reservoirs are divided into different stages of oil, gas and water systems. Based on in-house experimental data and well logging interpretation results, the reservoirs were identified and the geologic reserves were assessed. The geologic reserve per unit area （1 km²） is 47.21×10⁴ t. The per unit area （1 km²） of waterflood development is 21.75×10⁴ t. The research results can provide reference for the evaluation of oil and gas resources and the formulation of development plans for the Carboniferous reservoirs in the Marginal Caspian Basin.
