Abstract

To get maximum gas well productivity, this paper analyzes the influence of different fracture parameters on gas well performance and gets the qualitative principle of fracture distribution of fracture horizontal well with multi-fractures by the tight gas reservoir fracture horizontal well flow model. For quantitatively describing fracture parameter design (mainly fracture size and distribution), fuzzy mathematics is introduced and single factor subordinate function is established to form fuzzy evaluation model to qualitatively evaluate fracture parameters design.
