On basis of the analysis for cores and well-logging, the authors have thoroughly studied the sedimentary facies types and characters of Chang 6 oil-bearing formation of the Baibao region with casting thin sections, SEM, trace elements and porosity and permeability analysis and a great deal of indoor testing data. The authors propose that the sedimentary facies type of Chang 6 oil-bearing formation of the Baibao region is a sublacustrine slump turbidite fan for the first time, and lithology is lower componential and textural maturities micro-fine feldspar sandstone primarily, with graded bedding, fluidified convolute bedding, slipping-cut and deformational structures, minitype syngenetic faults, flute cast, groove cast, load cast and other turbidite sedimentary facies signatures.

The Es formation was divided into seven third order sequences based on the seismic, drilling and logging data, and plans deposition system plane distribution maps of different time were plotted by dominance phase principle. The lower Es4 is flood-overlake facies mainly; the upper Es4 is meandering stream and braided river delta deposition above the shore shallow lake background; in the Es3 period, the south mainly developed braided river, meandering stream delta, the northeast area main developed meandering stream delta, the middle area mainly developed semi-deep lakean d deep lake sediments. From lower Es3 to upper Es3, the delta scale gradually increased and the depositional area gradually moved to the east and the southeast; the Es2 period was dominated by shore-shallow lake sediments and widely developed braided river delta and delta deposits; the Es1 period was dominated by shore-shallow lake shoal deposits, and in the south developed meandering stream and braided river delta deposits.The lothological traps of the Shahejie group are mainly fluxoturbidite and stratum lateral pinch-out, and its formation and the distribution of the lothological trap were controlled mainly by the basin structure characteristic, palaeogeomorphology and tectonic activity and so on. It had a beneficial geological condition to develope sublacustrine slump turbidite fans in Jishan, Jiangjiadian and Wawu.
