Research and application of overall broadband fracturing technology in ultra-low permeability reservoir
In response to the difficulty of reservoir modification in ultra-low permeability reservoirs and the low production and efficiency,based on the initial modification,the overall repeated fracturing technology of well groups has been carried out.Through the concept of"controlling fracture length and increasing bandwidth"to modify reservoir,which can establish effective displacement and utilize the remaining oil.The results show that the implementation of broadband fracturing in the well group improves production efficiency,with a daily oil production increase of 0.77 tons compared to conventional measures,and the effective rate of the measures reaches 98%.
