Abstract

For low permeability reservoirs, the reasonable well pattern forms mainly depends on crack groups and bearing, Wells and well spacing depends mainly on fracture and the in situ stress field caused by seepage anisotropy, and the crack, the permeability ratio of the matrix;From the geologic features of low permeability reservoirs, in not equidistant well pattern development is an inevitable trend.Toward the 503 block of reservoir numerical simulation study results show that the rectangular way linear water flooding development effect is best, all kinds of well pattern and order of: rectangular linear injection pattern, method, square at 7 o 'clock pattern five points, square pattern against nine points.It is considered that the rectangular well pattern in the single well production, oil production rate and recovery degree, the water breakthrough time proof is better than other pattern, is currently the development effect of low permeability oilfield, the optimal solution. Using rectangular well pattern development can widen spacing, narrow row spacing, reduce the start-up pressure gradient, set up effective drive system, a low permeability reservoir is effective form of development pattern.
