Characterization and evaluation of fracture-cavity type carbonate reservoir in the western part of Northern Tarim uplift
摘要
Abstract
Fracture-cavity type carbonatite reservoir has strong dimensional anisotropism, and hence reservoir characterization and eval-uation are very difficult. The plateau facies carbonatite fracture-cavity reservoir is stably developed in Middle Ordovician strata in west-ern W block of northern Tarim uplift. Utilizing paleo-geographic coordinate transform, logging reservoir analysis and sensibility attribu-tor analysis of the fracture-cavity type carbonatite reservoir, the authors studied the reservoir facies. Based on reservoir facies research and utilizing stochastic method, the authors built the dual porosity model for fracture-cavity reservoir, and characterized the carbonatite reservoir. Finally, in combination with AVO inversion and reservoir characterization, the carbonatite reservoir was evaluated. It is proved that the reservoir pattern in the study area is mainly of the fracture and cavity type, with fractures acting both as hydrocarbon ac-cumulation space and as the factor for the formation of cavity. AFE ( Automatic Fault Extraction) and wave classification attribution were sensitive to the fracture and cavity type reservoir. With increasing oil saturation, AVO of the reservoir became more obvious. The fluid prediction method based on pre-stack AVO inversion could reasonably forecast oil province of carbonnate reservoir.关键词
