Abstract: The reasonable well pattern dispasitian is a key factor that low permeability ail fields are developed successfully because it is usually relative to fracture.This paper analyze conscientiously reasonable well pattern for developing low permeability ail fields after reviewing the evolution of well patterns for low permeability oil field.It hold that reasanable flooding pattern concerning develapment of law permeability oil field is linear water injection pattern along fracture direction with differ in well spacing.Some key questions of reasonable well pattern disposition about development of low permeability oil field were put for ward.We must get a clear understanding of fracture direction.the determination ratio of matrix permeability to fracture permeability on the basis of optimisation fracturing.Simultaneously well patterns that horizontal well to make use of developing low permeability oil fields were also approached.

Key words: low permeability oil field, development, fracture, well pattern, reasonable
