Abstract

Abstract: There is a significant difference in the development effect of water flooding displacement of well groups in fracturecavity reservoir units of H blocks. This study conducted research into the connection type of fracture-cavity units and water flooding development strategy. A geophysical method was used to describe micro-fracture, large-scale fracture, effective matrix, and pores, based on which three connection types of fracture-cavity unit were proposed:underground river karst conduit, largescale fracture, and dispersed fracture with large-scale fracture. Moreover, numerical simulation of and field test research on different fracture-cavity connection units were conducted; a rational water flooding development strategy was developed. The underground river system featured an injection-production relationship of low-injection high-production and cavity-injection underground river displacement production. For different units, there are differences in the matching of dispersed fracture with large-scale fracture and fracture-cavity connection units. As a result, it is advisable to take rational control over the injectionproduction ratio with follow-up dynamic adjustment to improve the recovery ratio of water flooding development and the water flooding displacement effect of connecting units in the block. This study is of reference and guiding significance for the same or similar water flooding development of connected units of fracture-cavity karst reservoirs.

Key words: development strategy, reservoir connection type, underground river, fracture, numerical reservoir simulation
