HQ地区长6储层岩石物理相分类与油层有效厚度研究
|
摘要
针对HQ地区长6储层具有低孔隙度、特低渗透率、复杂岩性、复杂孔隙结构及测井响应复杂的特点,利用岩石物理相分类研究特低渗透油层有效厚度确定评价岩石物理相的多种信息、划分方法及其分类评价。通过油区各类测井、岩心和试油资料,基于岩石物理相分类建立特低渗透油层有效厚度下限标准,阐明分类确定的参数下限变化,表达不同类别岩石物理相油层有效厚度下限差异及特征,避免了测井评价中有效储能和产能丢失,有效实现了将非均质、非线性问题转化为相对均质、线性问题,提高了测井精细评价解释油层有效厚度的精度和效果。
The Chang 6reservoir in HQ area,located in the formation with low porosity,lowpermeability,complex lithology and complicated pore structure,is influenced by multi-period sedimentary,diagenesis and structures.It is featured by complex logging responses.By the use of petrophysical facies classification in the area,the paper confirmed effective thickness of lowpermeability reservoir based on the analysis of all kinds of log data,core analysis data and formation tests.Considering relationships and categorization features,we picked out various information of different petrophysical facies,classification methods and evaluation system.The paper focusesd on the study of relationship among formation oil bearing,physical properties and electronic properties and established standards for minimum of the effective thickness in lowpermeability reservoir based on the petrophysical facies classification.Because of the properties in various petrophysical facies,it has significant difference and cannot be concluded in the same simple model.So the research illustrates the standard from petrophysical facies classification including reservoir parameters,and explains the differences of lower limit indicating the characteristic in classified model,therefore reducing the loss of the effective storage and productivity.It effectively transforms heterogeneity and non-linear into the opposite,and improves the fine log evaluation and interpretation accuracy of reservoir effective thickness.
