Rich Oil Regularity and Rolling Development Technology in Complex Fault Block Reservoirs

Abstract In view of the complex geological conditions and high drilling risk of TN Oilfield, analysising the influence of oil source, unconformity surface, fault properties and sandstone by strengthening the study of oil-rich regularity. The oil field has the characteristics of “near source reservoir, fault controlled reservoir, and enrichment of domi-nant facies”. The rolling development model of oil reservoirs has been established, which involves tapping the potential of fault zones and evaluating new traps, finely delineating the main sandstone in lithological reservoirs, optimal selection of favorable areas by matching the main sandstone with favorable traps, and achieving good development results.
