| Abstract: | Core observation and study of sedimentary facies in combination with the date of well-log, logging and chemical analyses indicate that the first Member of the Shahejie Formation in the Kai 38, 39 well field may be divided into fan delta front subfacies and pre-fan delta subfacies. The fan delta front subfacies may be subdivided into such four microfacies as underwater distributary channel, inter-underwater distributary channel, channel mouth bar and distal bar and frontal sheet sand. The underwater distributary channel and channel and channel sand bodies are is major reservoirs. |
