“Sweet spots” description and production capacity construction of Fuyu tight oil reservoirs in southern Songliao Basin

Abstract

Abstract: In southern Songliao Basin, tight oil was generated in upper formations and preserved in lower formations in the Fuyu Formation. With insufficient hydrocarbon charging, large-scale continuous tight lithologic reservoirs were formed. They can hardly be economically developed because of the strong heterogeneity, low permeability (<0.5 mD), low oil saturation (<50%), high water content (>80%), and low mobile fluid content (<20%). To facilitate the development of tight oil, fine reservoir description was carried out, and then, favorable structural setting and high gas-to-oil ratio were clarified as key factors controlling oil accumulation and productivity. On this basis, the techniques were developed to identify "seismic sweet spots", "development sweet spots" and "fracturing sweet spots". Thus, the drilling and stimulation performance of tight oil horizontal wells has been improved. Coupled with new operating mechanism, integrated management and market-oriented operation, the Fuyu tight oil reservoir has been economically developed in the Qian'an area, southern Songliao Basin.

Key words: Qian'an area, Fuyu tight oil, factors controlling oil accumulation and productivity, sweet spots, integration
