摘要
Based on core observation,analysis of electrofacies, sedimentary facies section and sand body distribution, the eighth member of Shihezi Formation of Block Su120 in Sulige gas field pertains to shallow braided river delta sub-facies. However,the development degrees of different distributary channel sand bodies are different.The inheritance presents that the amount and location of distributary channels of different sections almost remain the same.The migration presents that distributary channels always migrate towards either side,including 3 kinds of lateral migration,namely,eastward,westward,back and forth.
