Study And Application On Network Fracturing Techniques In Low Permeability Reservoir

Extra low permeability reservoir has the characteristics of small porous and throats, fluid flowing hard and so on, and it’s difficult to produce the wells when doing former hydraulic fracturing as before, so network fracturing was introduced and applied to the oilfield to increase stimulating area and increase the oil production. This paper analyzes the mechanics, the reservoirs condition of network fracturing, and puts forth the design concept, the treatment methods of network fracturing. Network fracturing has been sucessfully applied to DBA and HTZ field and achieves better effect. The study results of network fracturing have established the theory bases for the improve of network fracturing and field application.
