辽西低凸起变质岩潜山裂缝储层及成藏条件
|
摘要
在岩心、薄片及FMI全井眼微电阻率成像测井和地震相干体切片分析基础上,研究了辽西低凸起太古界变质岩潜山储层的岩石学特征、储集空间类型、垂向成像测井响应特征、含油层段物性特征及裂缝发育带平面分布情况。研究发现,该区的变质岩储层岩性包括混合岩类、区域变质岩类和碎裂岩类等三种类型;储集空间类型包括裂缝、溶蚀孔洞和微孔隙,其中以构造裂缝为主。利用成像测井和双侧向等常规测井解释总结出五种测井响应类型并描述其识别特征,结合孔隙度测井对含油层段孔隙度范围和测井响应特征对比研究,并依据相干体切片分析了反映构造裂缝发育程度的断裂信息维数与油气藏数目之间的定量关系,进而从垂向和横向上揭示有利储层分布,为成藏综合分析提供依据。
Based on analysis of cores,thin-sections,FMI imaging log and seismic coherent slices,studies were performed on the petrological characteristics,reservoir types,response of vertical imaging logging,physical pro-perties of oil-bearing strata and horizontal distribution of fracture zone in Archean metamorphic buried-hills of the Liaoxi low uplift.Three types of lithology were identified in the metamorphic reservoirs:migmatite,regional metamorphic rocks and cataclasite.Types of reservoir space include fractures,dissolution pore and micro-pore,among which structural fracture is the dominant type.Five types of logging responses were identified and described by interpretation of imaging logging and dual lateral logging. Combining porosity logging,a comparative study was performed on porosity range in oil-bearing layers and logging response characteristics.The quantitative relationship between the number of hydrocarbon reservoirs and information dimension that reflect development of structural fractures were defined based on the analysis of seismic coherent slice.The vertical and horizontal distribution of favorable reservoirs were revealed,laying the foundation for comprehensive analysis of hydrocarbon accumulation.
