松辽盆地长岭凹陷所图地区青山口组储层非均质特征
|
摘要
长岭凹陷位于松辽盆地中央坳陷区南部,所图油田位于长岭凹陷中南部。所图地区岩心、测井、地震剖面研究结果表明:所图地区青山口组储层孔隙类型主要为不发育的粒间孔、部分粒内溶孔和毛细孔,在301井区主力含油层段总体为中低孔隙度、特低渗透储层;该区青山口组储层宏观非均质性较严重,为"泥包砂"类型,砂体的连通程度较差。正韵律和复合韵律导致单砂层内存在粒度非均质性,构造特征导致渗透率的各向异性;该区青山口组储层微观非均质性表现为孔喉总体偏小,储层岩石的孔隙连通性不好,储层的孔隙分选较好,主要渗滤孔道集中程度居中,孔隙非均质性较弱。储层内不同方向颗粒大小等差异,导致了该区渗透率的各向异性。
Changling sag locates in Songliao Basin's south of the central depression area,Suotu Region is located in south central Changling sag.Based on the drill core records,well logging data,seismic profiles,rock thin sections,data of physical property,and Hg-injection test data,this study focuses on the reservoir heterogeneity of Qingshankou Formation.The results are summarized as follows.The majority of spaces in the reservoirs of Qingshankou Formation in Suotu region are undeveloped interparticle spaces,intraparticle dissolved pores and unmatured pellet internal pores.The main oil-bearing members in well 301 area are dominated by medium-low porosity and ultra-low permeability reservoir.The lamination factor and sandstone percentage by columnar section in the area imply a strong macroscopic heterogeneity,with a type of "mudstone-wrapping sandstone"and a weak connectivity of sandstone.The normal rhythm and composite rhythm lead to granularity heterogeneity in the single sandstone layer,and structures result in the heterogeneity of permeability,thus providing a strong permeability heterogeneity in the layers.The divergence of grain sizes in different directions results in the heterogeneity of permeability in the area.However,a weak heterogeneity is relatively shown in the horizontal direction.The microscopic heterogeneity in the area is characterized by generally small size spaces,weak reservoir spaces connectivity,good sorting,medium concentration of main infiltration passageway,and weak heterogeneity.
