Abstract: To improve the effect development of Huangjindai oil field, which is characteristiced by faults, reservoir changed frequently and complex oil-water contact relationships, its sedimentary characteristics, reservoir lithology, petrophysical property and heterogeneity are studied in detail with core, analytical experiment and logging data.Oil-bearing sand bodies are traced and predicted using JA SON software, new wells are deployed in favorable areas.Geology basis has been established with study results in the progressive development of Huangjindai Oil Field.
