摘　　要：基于岩心、测井、录井等资料,进一步研究苏里格气田X井区山1段的沉积微相及砂体分布特征。结果表明:山1段在三角洲平原亚相背景上发育河道间、河道充填、边滩、堤岸等微相,其中河道充填和边滩为主要控砂微相类型;山1段各小层砂体顺物源方向逐渐变厚,其中山1^(1)小层砂体发育最为充分,山1^(2)、山1^(3)小层砂体发育程度相当;有效砂体以垂向叠加型和横向接触型为主,其中山11小层的有效砂体发育最为充分。Based on core,well logging and other data,the sedimentary microfacies and sand body distribution characteristics of Shan 1 section in X well area of Sulige Gas field are further studied.The results show that microfacies such as inter channel,channel filling,edge beach and bank are developed on the subfacies background of delta plain,and channel filling and edge beach are the main sand-controlling microfacies types.The sand bodies of the Shan 1 section gradually thicken along the direction of the source,and the sand bodies of the Shan 1^(1) formation are the most fully developed,while those of the Shan 1^(2) and Shan 1^(3) formations are equally developed.The effective sand bodies are mainly vertical superposition type and transverse contact type,among which the effective sand bodies of Shan 11 formation are the most fully developed.
