| Considering the geological characteristics and development heterogeneous block reservoir in Lin13 area of Linpan,oil-fieled,applying ecploration and development data,guided by the theory of petroleum geology,sedimentology,reservoir geology,development geology and reservoir engineering,adopting the technical means of high-resolution sequence stratigraphy,fine description of lower Es2 in Lin13 aera in Linpan oil-field have been studied.Analyaing the background and characteristics of sedimentary and core, the microfacies of the formation are studied. The conclusion is that this area is at the frontal delta zone, the submerged distributary channel, the submerged interdistributary channel, the channel-mouth bar, the far sand bar and the interbar. The main reservoir sand is river sand and the rest is of channel and sand sheet. Comparing the framework profile,lower Es2 is divided into five sand units and 43 reservoir beds.This is very helpful for fine reservoir description. The reservoir rock physics property is analyzed with a lot of maethods such as analyzing diagenesis, granularity, general reservoir properties and watching core and slice, etc. Considering the high shale content, poor rock difference and litho-electric, difficult physics interpretation in this area,a better reservoir interpretation model for this area is presented by using the calibrated logging and single well sectional physics interpretation. Analyzing the attributes of the formation,the heterogeneous interpretation is studied. Finally, logging data have been reinterpreted and reprocessed, and established the logging interpretation model using the relationship between core and logging response, porosity mode and permeability model has been simulated by using sequential Gauss simulation under the control of sedimentary. reservoir model has been simulated by using sequential indicator simulation.These models are used for research of the remind oi1distribution in reservoir engineering.
