Abstract: Sulige gas field was formed in the low permeability of fluvial background under tight sandstone gas reservoirs,the deposition conditions and reservoir properties determine its development difficulty is great.Combined with the overall deployment of horizontal wells and fracturing technology,high efficient and high-yielding gas field development has been achieved.Starting from the geological guidance of horizontal wells deployment,by taking as the overall economic efficiency as the target,the optimization and application of well spacing,horizontal length,orientation,wellbore position,the pressure fracture length,fracture size and other aspects have been carried out.In the end,agood development result has been achieved in Su-53 block.
