Optimization of Hydraulic Fracturing Parameters in Bai 257 Well Area of Huaqing Oilfield

Reasonable fracturing parameters is the key and the difficult part of the fracturing design,and it determines the success or failure of the fracturing.On the base of analyzing the fracturing geological characteristics of Bai257 well area and put forward a method that using the result of the small scale fracturing test and the net presssure fitting to set a fracturing template,then optimized the fracturing parameters on the base of the template.Finally,get the reasonable fracturing parameter's,the reasonable delivery rate is 1.8~2.0 m3/min,the preflush rate is 15%~30%,the sand volumn is about 30 m3,average sand liquid ratio is about 30%.The optimizing results makes the well performed better than the neighboring well which fractured formerly.
