- Abstract
The Shan1 of the Ordos Basin is the main gas producing layer of the Jingbian gas field. To clarify the types of sedimentary microfacies and the distribution pattern of sand bodies in the study area, based on core observation and description, single well facies analysis, and comparative analysis of connected well sand bodies, the distribution characteristics of sedimentary microfacies types and sand bodies in the study area were studied. The results show that the Shan 1 has developed a river delta front subfacies, which can identify microfacies such as underwater distributary channel, mouth bar, and interdistributary bay. Underwater distributary channels are mainly developed in the central and northern parts of the research area, distributed in a nearly north-south direction. In other areas, sand bodies are mainly distributed in the form of river mouth bars, forming clusters and blocks. Controlled by the instability of river estuaries, multiple periods of distributary channel sediments migrate back and forth, resulting in rapid lateral changes and poor connectivity of river delta sand bodies.
