Fracturing and Acidizing Results Prediction Model of Injectors in Xingnan Oilfield of Daqing

Hydraulic fracturing and acidizing technology are important measures for oil and gas wells stimulation. In low permeability oil fields, fracturing and acidizing technology not only can improve the injection volume of single layer but also adjust interlayer contradictions. So, this technology is important to maintain formation pressure and improve production rate and recovery factor. According to the decline rule analysis of injectors before and after fracturing and acidizing, and the injection volume changes of 189 injectors in Xingnan oilfield of Daqing, the functional relation between injected volume of injectors and various main influential factors is established. This model is suitable for fracturing and acdizing results prediction of injectors in Xingnan oilfield, and can be helpful for evaluation of injector stimulation measures.
