The metamorphic rock buried hill have a large amount of reserves. Because its low permeability in the matrix, most wells drilled in the field have to be fractured before production. It has large thickness of reservoirs, massive hydraulic fracturing is difficult, the cost is high. In this paper, successful cases of volume fracturing technology applied to metamorphic buried hills were introduced. The results prove its feasibility by theoretical calculation and numerical simulation, etc. Clustering perforation mode, low viscosity and low friction fracturing fluids were used in combination. With high rate of fracturing fluids, low proppant concentration, the technology could realize maximum communication among the natural fractures, greatly improving the overall permeability of the reservoirs, and realizing the three dimensional treatment to the reservoirs. Down hole micro seismic fracture monitoring results indicate that the induced fracture volume increased by 28.8% compared with that in conventional fracturing. In addition, average single well production increased by over 50% after fracturing with this technology compared with that by conventional fracturing of vertical wells from the same block. Since 2013, in addition, average single well production increased by over 50% after fracturing with this technology compared with that by conventional fracturing of vertical wells from the same block.
