    Abstract
  • Due to the high cost for exploration and development of tight oil reservoirs, it is an urgent problem to achieve profitable development of tight oil. According to the characteristics of tight oil reservoir in the eighth member of Triassic Yanchang Formation (Chang 8) in Honghe oil field, Ordos Basin, this paper highlighted single well information, started with the key parameters affecting the economic benefit of tight reservoir-single well economically recoverable reserves, and established a series of determination methods and process of geological evaluation parameters for profitable development of tight oil reservoirs based on single well economically recoverable reserves. Considering the particularity that the single well recoverable reserves of Chang 8 tight oil reservoir in Honghe oil field was controlled by fractures, the fracture development degree was added in the study of determination of the geological evaluation parameters. Five parameters, including single well technically recoverable reserves, net pay thickness, effective porosity, oil saturation and fracture development degree, were selected for classification and subdivided into six types. By compiling the intersection diagram of single well technically recoverable reserves and net pay thickness, the cutoffs of geological parameters were determined comprehensively by comparing the economic cutoffs and the classification of reservoir geological parameters under two scenarios. The method was applied to Chang 8 reservoir in Honghe oil field, and its feasibility was verified. The practical application shows that this method can provide effective technical support for sweet spot screening and development and deployment optimization in tight reservoirs.
