The variations in trace element contents and ratios may hold up a mirror to the lake - level fluctuations and climatic changes, which, in turn, have exerted a direct and important effect on the sequence stratigraphic development. collectively, the reservoir rocks from the yanchang formation consist dominantly of the delta front subfacies subaqueous distributary channel and channel - mouth bar microfacies and delta plain subfacies subaerial distributary channel microfacies fine - grained feldspar sandstones and siltstones. the reservoir rocks have been subjected to three stages of diagenetic and porosity evolution : ( 1 ) the porosity reduction by the mechanical compaction and chemical pressure solution during the early diagenetic stage ; ( 2 ) the porosity increase by the dissolution during the a substage of the late diagenetic stage, and ( 3 ) the porosity reduction by the cementation and filling during the b substage of the late diagenetic stage
系統的儲層特徵研究表明，該區延長組儲層成因類型主要為三角洲前緣水下分流河道、河口砂壩及三角洲平原水上分流河道微相細粒長石砂巖、粉砂巖；儲層巖石經歷了壓實，膠結，溶蝕等成巖作用，歷經早成巖機械壓實和化學壓溶孔隙縮小期、晚成巖a亞期溶蝕作用孔隙擴大期及晚成巖a亞期（ b亞期）膠結充填孔隙縮小期三個成巖-孔隙演化階段；儲層物性總體上具有較低孔滲、低孔滲的特點，孔隙類型主要為粒間溶孔、殘余粒間孔隙、粒內溶孔、晶間孔及晶間溶孔，裂縫不發育，儲集巖排驅壓力和中值壓力較高，孔隙結構類型以細小孔-微孔隙，微細喉-微喉型為主。
