摘　　要：白云岩系分布于泌阳凹陷东南部的安棚-安店地区,平面分布稳定,纵向上分布于古近系核桃园组核二段-核三上段。其岩石成份以铁白云石、铁方解石为主,大多具有泥晶结构,层理类型以水平层理、波状层理和透镜状层理为主,经历了强烈的压实作用。白云岩系储集空间类型多样,以溶孔溶洞、裂缝和孔隙为主,物性较差。研究认为只有找到白云岩孔洞缝发育段,才能找到有规模的白云岩类油藏。Dolomiteis scatter in the Anpeng areas of the south-east of the depression.distributed horizontally stable,vertically distributed in the period of upper H3-H2.Rock is composed from hard dolomite,ferrugious calcite primarily.Most of them has the micrite texture.Level lamination,cur-rent bedding and lens primarily are the main microscopic structure which experienced the intense compress function.The dolomite rock reservoir spacetype are various primarily with dissolved hole,Limestone cave,cracks and pore.The physical properties is worse.It is thought that only the dolo-mite hole linking development can prove the largescale dol-omite class oil deposit.
