Application of fuzzy recognition method to Wuliyastai depression reservoir fracturing

Wuliyastai depression reservoir is a new developed oilfield,and its bed plane distribution is unequal,it’s can’t be analyze perfectly by tradition fracturing software.In view of fuzzy recognition can get regularity from ambiguity things,analyzed fracture parameters of Wuliyastai reservoir,and selected fracturing wells and layers of it,optimized working parameters to enhance fracture effect.Statistical and analyzed formation parameters,working parameters and production data of 20 wells before fracturing and after fracturing,looking for stimulate regular of fracturing.From this,use fuzzy recognition model to select well and layer of fracturing,and optimize sensitivity of working schemes and parameters by it.Applications show that this method is simple and easy to do,select wells and layers of fracturing can fit well with the actual of oilfield,and selected working parameters and schemes have well stimulation effect.It can be used as fracturing directions of Wuliyastai Oilfield.
