Abstract

Abstract: According to the reservoir development characteristics, fluid seepage law and five-point well pattern characteristics of low permeability reservoirs, a water breakthrough time calculation model considering pressure-sensitive effect, variable starting pressure gradient, well spacing, fracture and well spacing angle, fracture length, heterogeneity and other factors is established, and the influence law of different factors on water breakthrough time is analyzed. Compared with the existing results, the water breakthrough time calculation model established in this paper is more comprehensive and fits the actual situation of the mine better. The analysis results show that the larger the ratio of well spacing to row spacing, the stronger the heterogeneity; the longer the fracture length, the smaller the starting pressure gradient and the original formation pressure, the earlier the water breakthrough time. With the increase of fracture and well row angle, the water breakthrough time changes, when the water saturation is between 0.4~0.5, the water breakthrough occurs early. The research results can provide theoretical support for the development adjustment scheme of low permeability fractured reservoirs.

Key words: low permeability reservoir, well spacing and row spacing, crack and row spacing angle, pressure sensitive effect, heterogeneity
