The effect of Markov chain models in reservoir modeling is much concerned recently, but models are usually applied to simulating categorical attributes, such as lithofacies, sedimentary facies and subfacies, and very few to continuous attributes, such as porosity, permeability and oil saturation.

Markov链模型在储层随机建模中的作用越来越受到关注，但其多用于类型属性(岩相、沉积相、沉积亚相等)的模拟，对于连续型属性(孔隙度、渗透率、含油气饱和度等)的模拟还比较困难。

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.

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.
