苏X井区位于鄂尔多斯盆地西北部苏里格气田中区的南部,其主要砂体类型为一套典型的曲流河相沉积产物,该储层总体上具有低孔、低渗和非均质性强的特征。因此应用高分辨率层序地层学原理对山1段层序划分,为后期的开发提供了有力理论依据。通过对山1段的研究将其划分为1个长期旋回、3个中期旋回和7个短期。 Well SU X is located in the southern part of the central Sulige gas field in the northwestern Ordos Basin. Its main sandbody type is a typical stream-flow sedimentary product with low porosity, low permeability and heterogeneity Strong features. Therefore, applying the high-resolution sequence stratigraphy principle to the sequence division of the Shan 1 block provides a strong theoretical basis for the later development. Divided into a long-term cycle, three mid-cycle and seven short-term through the study of the first section of the mountain.
