Application of close cut volume fracturing in tight oil horizontal Wells

S tight reservoir is rich in oil and gas has good development potential. However, the lacks physical property, strong heterogeneity, lithology complex formation conditions, fracturing operation characterized by lack of fracture complexity difficulty initiation. For geological characteristics difficulties reconstruction, we actively follow principle fracture-controlled reserves, broaden understanding unconventional volume fracturing, integrate cutting technology long-term practice process. The combination cluster perforation, plug segmentation, reverse mixed injection other methods can fully improve initiation extension effect multiple clusters. sand addition smooth water to replace guar gum, promote laying quality proppant be improved, further achieve energy storage increase goal, layer transformation long-term, stable reconstruction.
