Discussion and application of thin-layer sand connectivity of outer front facies

In this paper, the microfacies of thin-layer sand outer front facies are described by homogeneous unit thickness classification in past, plane distribution single body and connection relationship between different types roughly understood; From two aspects vertical single-stage identification fine description sedimentary belt map applying energy microfacies, is divided into 6 9 kinds combinations, connectivity bodies clearer directionality clearer. The application research results not only deepens geological understanding, but also guides adjustment water-driven scheme.
