摘要:
利用岩心描述、铸体薄片、扫描电镜和岩矿分析等手段,对鄂尔多斯盆地镇泾探区长9储层砂岩的成岩作用及其对储层物性发育的影响进行了分析研究。结果表明:研究区储层砂岩经历了压实、胶结、溶蚀、交代和重结晶五种成岩作用类型,其中压实作用使得塑性岩屑发生弯曲变形、刚性岩屑碎裂,导致原生孔隙大幅度减少;方解石胶结物在某些井位和层段中含量可达25%,并形成连生胶结,造成砂岩的孔隙度损失严重;溶蚀作用形成的次生粒内溶孔(包括少量粒间溶孔)增加了研究区储层砂岩平均值为287%的面孔率。长9储层砂岩处于晚成岩阶段A期的晚期至B期的早期。
Abstract:
With the use of core description,casting thin sections,scanning electrom microscopy and rock ore analysis etc.,the diagenesis and its influence on the reservoir quality of Chang 9 reservoir sandstone in Zhenjing exploratory area,Ordos Basin,was analyzed and researched.The results showed that the sandstone reservoir in the study area experienced five types of diageneses: compaction,cementation,dissolution,metasomatism,and recrystallization.The compaction made the plastic debris bending deformation and rigid rock splintering,leading to the great reduction of primary pores.In some locations and intervals,calcite cement content can reach 25% and form cementation,making serious loss of sandstone porosity.The secondary solution pores,generated by dissolution,including a small amount of intergranular dissolved pores,increased the face rate of rock by 2.87%.Chang 9 reservoir sandstone was at the late A stage to the early B stage of the late diagenetic period.
