摘要
Based on the geological analyses of the cores, well logs and so on, the depositional model of sublacustrine-fan glutinite body is established. The analyses show that the sublacustrine fan is composed of feeder ehannel, inner fan, middle fan and outer fan, and furthermore the fan can be divided into feeder channel, main channel in inner fan, braided channel in middle fan, turbidite channel in outer fan micro-faeieses and so forth. Among the above, Inner fan, middle fan and outer fan are the maim parties of sublacustrine fan and located on the downthrow wall of contemporaneous fault and belong to half-deep lake sedimentation; feeder channel is the "root" of sublacustrine fan located on the upthrow wall of contemporaneous fault and belongs to shallow lake sedimentation.
