摘要：In order to study the oil and gas enrichment of the Chang 2_3 reservoir in the Yanchang Formation of the N138 block in the Heshui area of the Ordos Basin, on the basis of the fine division and comparison of the small layers, logging data, scanning electron microscopy, cast thin sections, and high pressure mercury intrusion analysis, and multi-phase seepage core experiments, etc. are used to study the characteristics of sedimentary facies and reservoir distribution characteristics. The study shows that the Chang 2_3 reservoir is the delta front subfacies deposit, the river channel is distributed in the southwest-northeast direction, and the underwater distributary channel is the most favorable sedimentary facies belt. The Chang 2_3 reservoir is mainly controlled by structure, and the sedimentation is equal to it. The impact is a typical lithology-structural reservoir.
