Jurassic Badaowan Heavy-oil Reservoir Description In Hongqian Area Of The Northwest Zhungaer Basin

Hongqian area is located in the northwest of the Zhungaer basin, heavy-oil reservoir of Jurassic Badaowan formation have began the product input since 1990. During the 15 years, it have undergone the oil-recovery technology of cyclic-steam-stimulation and steam-driving, but the output of oil reserves have been lapsed year by year. Because of strong heterogeneity and fluidity difference of the inside reservior, high wheel cyclic-steam-stimulation, more low-effect well and bad exploitation benefit, therefore, it has employed lower section of oil reservoir and greater surplus reserves in the present. This paper studies a lot of discipline theory and research method of Sedimentology, Structural Geology, Petroleum Geology, Reservoir Geology, Logging Geology and Reservoir Assessment Technology, with the guide of the newest theory of heavy-oil accurate reservoir description, synthesized the record of drilling, logging and analysis assay, with the oil reservoir description software of the Sufer and the Carbonsoft, with the logging explanation software of the Forward and with measure of the three dimensions of geology establishment model module of the Storm RMS software. From static research to incorporate product dynamic record of oil reservoir, proceed accurate description research of formation characteristics, structural characteristics, sedimentary microfacies, reservoir characteristics and fluid characteristics, accurate description heterogeneity characteristics and combine surplus reserves distribution research to establish the high precision of the three-dimensional geology model, it has pointed out the future profitable encryption direction of rolling exploration and exploitation of reservoir, the first is near by the Hong3017 well, Hong3018 well and Hong3023 well district, the second is near by the Hong3057 well, Hong3067 well and Hong3083 well district, the third is near by the Hong1146 well, Hong1147 well and Hong1155 well district. It has pointed out the future profitable enlargement direction, the first is near by the Jian430 well district which both clip Hongqian12 well fracture and Hongqian8 well fracture, the second is the northwest of Hong two district near by Hong three district and the southwest of Hong three district near by Hongqian8 well fracture and Hongqian 14 well fracture, the last is the Jian408 well to the Jian407 well district near by the southwest district. Furthermore, It have found that...
