摘要
对泥页岩油气评价的"五性"指标,即矿物组分含量、地化参数指标、储层物性、含油气量和可压裂性进行探讨。建立新的泥质、砂质和灰质矿物模型;对烃源岩的重要参数有机碳含量、有机质成熟度及类型进行研究,并建立有机碳含量与密度关系式;提出一种适用于泥页岩的新孔隙度模型、矿物组分渗透率模型,新的矿物组分含水饱和度模型。探讨页岩油气量的计算方法,并对可压裂性进行分析。实际应用分析表明测井资料在泥页岩评价方面可以取得很好的评价效果。
Five kinds of geophysical parameters are used to evaluate shale hydrocarbon reservoir based on analyzing logging data. These parameters refer to mineral component contents, geo- chemical parameters, porosity and permeability properties, reserve of hydrocarbon and fractur- ability. New clay, sandy and calcareous mineral models are created and the important parameters of the source rocks such as organic carbon content, maturity and types of organic matter are dis- cussed, based on which, the relationship is set up between organic carbon content and density. New porosity model for shale reservoir is proposed, and mineral composition permeability model and mineral composition water saturation model are also built. The methods for calculation of shale oil and gas volume are described, the fracturability is discussed. Case study shows that well logging data is feasible and effective in shale hydrocarbon reservoir evaluation.
