摘要:
柴达木盆地英西地区湖相碳酸盐岩具有明显的混积特征,矿物成分多样且垂向变化频繁,存在晶间孔、裂缝和溶蚀孔等多种储集空间类型,储集层非均质性极强,仅应用常规测井资料难以得到准确的矿物含量、孔隙度和孔隙结构信息,有效储集层识别困难。应用地层微电阻率扫描成像(FMI)测井、岩性扫描测井、常规测井和岩心分析等资料,基于岩石矿物组分,利用变骨架方法准确求取基质孔隙度,构建基质储集层因子,结合裂缝参数、FMI岩石构造、缝洞视面孔率和测试资料,建立了湖相混积碳酸盐岩储集层综合分类图版和分类标准,该标准在英西地区取得了较好的应用效果,也为其他地区复杂碳酸盐岩储集层测井评价提供了参考。
Abstract:
Compared with marine carbonate rocks, Yingxi lacustrine carbonate rock is characterized by mixed sediments, variable lithologies and diverse minerals. There are various types of reservoir spaces including intercrystalline pores and fractures as well as dissolved pores, leading to extremely high reservoir heterogeneity. It is hard to get accurate information about mineral content, porosity and pore structure only by using conventional logs, and effective reservoirs are difficult to be identified. In this paper, based on the data of FMI logging, lithoscanner logging, conventional logging and core analysis, the matrix porosity is accurately calculated by using variable skeleton method according to rock mineral components, the factors of matrix reservoir are constructed, and the integrated reservoir classification chart and classification standard for mixed lacustrine carbonate reservoirs are established by combining with test data, fracture parameters, FMI structure and apparent surface proportion of fractures and pores. The actual application result of the classification standard in Yingxi area is pretty good, providing references for logging evaluation of the complicated carbonate reservoirs in other areas
