Sedimentary Microfacies and Sand Body Distribution Characteristics of Shan 1 Section in the X Well Area of Sulige Gas Field
Based on core, well logging and other data, the sedimentary microfacies and sand body distribution char-acteristics 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 11 formation are the most fully developed, while those of the Shan 12 and Shan 13 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.
