【摘要】：多孔介质储层表征技术应用岩心分析、测井分析、地震分析、岩样实验分析、生产动态分析等多种分析方法,表征不同尺度储集空间及其组合特征,最终评价有利储层。应用该技术,识别塔中地区北斜坡奥陶系良里塔格组孔隙型、孔洞型、孔隙-孔洞型、缝洞型和孔缝洞型5类储层,并表征了各类储层的孔喉结构、孔渗性和产能特征。结果表明:孔隙-孔洞型储层的孔喉结构发育大孔大喉的孔喉结构,优于孔隙型和孔洞型储层;裂缝对各类储层起到改善作用,裂缝的发育增加了储层孔渗性和连通性;储层产能特征受储层类型及规模影响,台缘孔缝洞型、孔隙-孔洞型储层以高产稳产为特征,台内缝洞型储层以中产较稳产为特征,台内孔洞型储层以中低产不稳产为特征。各类储集空间组合类型中,台缘孔缝洞型、孔隙-孔洞型储层是最有利储层,台内缝洞型是目前台内勘探的主要类型,台内孔隙型、孔洞型储层在裂缝发育情况下可以形成潜力储层。
[Abstract]:Reservoir characterization in porous Media using core analysis, log analysis, seismic analysis, sample experimental analysis, production dynamic analysis and other analytical methods, the reservoir space and its combination characteristics of different scales are characterized. Finally, the favorable reservoir is evaluated. By using this technique, five types of reservoirs, such as pore type, pore type, pore type, pore type, fracture type and fracture type, are identified, and the pore throat structure of all kinds of reservoirs is characterized. The results show that the pore throat structure of the pore cavity reservoir is superior to that of the pore type reservoir, and the pore throat structure is superior to that of the pore type reservoir and the pore cavity type reservoir, and the fracture plays an important role in the improvement of the reservoir. The development of fractures increases the porosity and permeability of the reservoir, the reservoir productivity is affected by the reservoir type and scale, the porosity and porosity type of reservoir is characterized by high and stable production, and the middle production is relatively stable in the reservoir. Among the various types of reservoir space assemblage, the porosity and porosity type are the most favorable reservoir, and the fracture and cavity type in the platform is the main type of exploration in the platform at present, and the pore type in the platform is the main type of exploration in the platform at present, and the pore type in the platform is the main type of exploration in the platform, and the porosity type in the platform is the main type of exploration in the platform at present. The potential reservoir can be formed under the condition of fracture development.
