摘要/Abstract

摘要： Taking Ha-6 well block as an example, based on the study of reservoir distribution and spatial relationship of oil and water in the study area, this paper analyzes the development features of producing wells, establishes 3 patterns of oil and water distribution in fracture-vug complexes which can be identified from single wells—separate oil and bottom/edge water connection pattern, separate water and bottom/edge water connection pattern and composite fracture connection pattern, and demonstrates the causes of the 3 patterns and the production characteristics. The paper also presents 3 performance analysis methods to identify fracture-vug complexes, i.e. production test data analysis method, waterflooding type curve analysis method and elastic productivity analysis method, and demonstrates the correspongding identification methods applicable for each fracture-vug complex. Combined with the principle of planar distribution area determination for fracture-vug complexes, 3 types of fracture-vug complexes are identified in the study area.
