摘要
应用沉积学理论,通过岩心观察、室内薄片研究及扫描电镜、阴极发光等测试分析,对靖边气田陕200井区的成岩作用进行了研究。认为本研究区马五1小段为灰色细粉晶白云岩,斑状溶蚀孔洞和晶模孔发育,储集空间多以次生溶蚀孔洞为主。根据溶解、胶结和充填等成岩作用,以及最终孔洞保存情况,马五13共划分了4个成岩作用区。
Based on the observation of cores and slices,sedimentary theory and SEM/CL technology,the paper studies the diagenesis of carbonate rock in well block Shan 200, Jingbian gasfield.The conclusion shows that Ma51 is a thin gray dolomite powder,macular holes and grain dissolution porosity mode.And its reservoir space is mainly based on secondary solution opening.According to dissolution,cementation and filling,as well as the preserving situation of the final hole, Ma51^3 is divided into 4 diagenesis blocks.
