Abstract: Network fracturing technology is widespread to development of shale oil?gas reservoirs in North America, with remarkable effectiveness and/or success. In this paper, the conception and characteristics of network fracturing technology are summarized. From geology and construction technology, the factors influencing the formation of complex network fractures are analyzed, and the key points of such a technology applied in different reservoir conditions are presented. The numerical simulation study indicates that the network fracturing can improve the single well productivity tremendously than the conventional fracturing technology, and fracture network system may allow the pressure sweep efficiency to be more uniform, with obvious advantages of development effect. Aiming at domestic tight oil reservoirs characteristics, the ideas should be studied from three aspects as follows: the tight oil accumulation mechanism, the evaluation of tight oil reservoirs before fracturing and the induced stress field and fracture/crack initiation mechanism so that provide some references for the development of network fracturing technology for tight oil reservoirs in China
