In this paper, based on the sedimentary facies and sedimentary facies geological theory,by field geological survey and indoor geological research, the combination of comprehensiveregional geological background, lithological assemblage characteristics, sedimentary tectoniccharacteristics, geological logging, paleontology, etc, to study the Chang2Jianyucha area ofZibei oil field, development Law reservoir sedimentary microfacies and distribution rulesreservoirs and small layer of sand bodies. Determine the division standards of purpose of eachsmall layer, describes in detail the lithology and electrical characteristics of each layer. Fromthe formation lithology, sedimentary structure type, and particle size analysis and electricalcharacteristics, make a single well of phase deposition profiles than sand, sand thicknessplanar distribution patterns. The results determine the group of Chang2reservoir braided riverdelta delta plain deposits, sedimentary microfacies have distributary channel, between the riverand the river flank, flank the river can be divided into natural and crevasse splay. the mostdeveloped micro-phase is distributary channel.
