By synthetically using the core analyzing results of Well L11-6, log curves and their processing results etc. , the author believes that the interlayer types are mainly clay and calcium in the delta front sand body, followed by a transitional sandwich, and establishes the standards of identifying the electrical and reservoir properties of various types of interlayers. Second, the author analyzes the interlayer distribution of underwater distributary channels and estuary dam sand bodies in the delta front subfacies considering the microfacies distribution and taking full advantage of the dense well system in the exploitation section. The author believes that the main types of interlayers are clay layer and calcareous interbeds in the underwater distributary channel, their lateral distribution is unstable, and the dip angle is less than 2° in a general way.
