Reservoir Description Of Zi115- Zi113 In Zichang Oilfield

Chang 2 reservoir is the main development layer in Zi115、Zi113 well district of Zichang oilfield.The reservoir is buried shallow, the wells with the characteristics of the high initial production and declines fast. In order to improve the level of oilfield development and increase the recovery rate, the reservoir description level must be improved,develop the research of reservoir characteristics. Based on the previous studies, this paper has carried out the research on fine division and comparison of the strata, structural characteristics, the sedimentary facies of the reservoir, the geological constraints of the well logging reservoir evaluation and the two processing and reservoir evaluation. During the research, the regional key-layer K9 and the auxiliary key-layer were used to do fine strata division and comparison. The 60 strata correlation sections were established, by this way, the correlation of the strata in the whole region was achieved. The standard of oil and water level discrimination and the lower limit of the material property was established in this paper, the two time processing of logging data was carried out, and the static database of reservoir parameters is established. It Provides sufficient theoretical basis for the Zi Chang oilfield in the scientific development of the next step.
