Oil Potential Evaluation Research Of Fuyu Reservoirs In Daan Oil Field

Based on the core description, geochemical analysis and related logging permeability curve of experimental data, the Da an Oil Field of Fuyu reservoir poroperm characteristics,what are the main controlling factors of oil in the reservoirs, and other issues, through the division level and therefore the classification recognition after classification, to achieve the goal of oil reservoir evaluation. Da an Oil Field is located in the southern songliao basin in the central depression area big AnGong terrace of secondary tectonic belt, the study of fluvial-dominated delta sedimentary system, the main development of formation change is relatively complex, exists ultra-low permeability sandstone reservoir. Combining macro sedimentary characteristics and microscopic reservoir structure characteristics, using experimental method in combination with production data, it is concluded that the distributary channel microfacies in the area are mainly composed of oil, oil and grease spots, debouch bar microfacies of staining, fluorescence and not oily, sheet sand microfacies for staining and not oily, natural levee microfacies are not oily, between the thin layer of sand microfacies for oil spot, fluorescence and not oily. According to relevant data, to establish the relationship between the log and therefore division templates, provide a reference for Dan an oilfield in fuyu oil layer follow-up studies.
