摘　　要：以物性、铸体薄片、X衍射、扫描电镜等基础测试资料将神木气田山西组及太原组划分为5种成岩相类型,结合自然伽马、声波时差、中子、密度、电阻率测井资料,建立了测井响应与成岩相之间的对应模型。利用该模型对双34井进行单井成岩相划分,并通过铸体薄片资料对其准确性进行验证。根据成岩相测井识别结果,对本区其余开发井进行解释划分并绘制成岩相平面分布图。The diagenetic facies of Shanxi formation and Taiyuan formation in Shenmu Gasfield is divided into 5 kinds according to the basic data such as physical property,casting thin sections,X-ray diffraction,electron microscopy scanning,etc.,and the corresponding relationships between logging responses and diagenetic facies are established based on the diagenetic facies classification and the natural gamma ray,acoustic time,neutron,density and resistivity logging data. The diagenetic facies of Shuang 34 well is divided according to the relationships,and the divided result is verified by casting thin sections. The logging identification of diagenetic facies of other wells in the study area is carried out,and the interpretation result is made into a plane distribution map of diagenetic facies in the study area.
