【摘要】：近年来,非常规油气勘探开发取得重大突破,大大拓展了储层研究内容,有力推动了储层研究方法的创新。对储层孔隙结构和孔渗特征的认识因新技术的应用而拓展,从常规尺度到纳米级孔隙,从低孔低渗到超低渗储层。文章在介绍和比较孔隙表征的多种方法基础上,根据孔隙结构和储渗特征将储层分为大—中孔高渗储层、微孔低渗储层、纳米孔超低渗储层和复合型孔隙储层4类,并针对不同类型的储层探讨了各个表征方法的优缺点和有效范围,提出了适用于不同类型储层的表征方法组合,针对复合型孔隙储层提出了分区—分层表征技术。此外,文章还探讨了这些表征技术在孔隙成因、孔隙内壁表面结构、充填物特征等研究方面的应用,将储层表征技术从储层品质研究延伸到成因研究,为更加全面综合认识和评价储层提供参考。
[Abstract]:In recent years, unconventional oil and gas exploration and development have made a major breakthrough, greatly expand the reservoir research content, and promote the innovation of reservoir research methods.The understanding of pore structure and pore permeability characteristics of reservoir is expanded by the application of new technology, from conventional scale to nanometer pore, from low porosity and low permeability to ultra-low permeability reservoir.On the basis of introducing and comparing various methods of pore characterization, according to pore structure and reservoir and permeability characteristics, the reservoir is divided into four categories: large and medium porosity and high permeability reservoir, micropore and low permeability reservoir, nanometer pore ultra-low permeability reservoir and composite pore reservoir.The advantages and disadvantages and effective range of each characterization method are discussed for different types of reservoirs. The combination of characterization methods suitable for different types of reservoirs and the zone-stratified characterization technology for composite pore reservoirs are put forward.In addition, the paper also discusses the application of these techniques in the study of pore origin, pore inner wall surface structure, filling characteristics, and extends reservoir characterization technology from reservoir quality study to genetic study.It provides a reference for more comprehensive understanding and evaluation of reservoir.
