Shale gas is mined from shale in natural gas, is an important unconventional gas resources. Compared to more conventional natural gas, shale gas development has a long life and exploitation of the advantages of long production cycle, most of the shale gas production and wide distribution, thickness, and generally containing gas, which makes shale gas wells to a stable long-term rate of gas production.

Oil fracturing support is very effective
When oil and gas exploration in deep, high pressure low permeability Deposits closed after fracturing treatment, the rock cracked hydrocarbon, oil and gas from the channel formed by the collection out of the cracks. Along with a high-pressure high-alumina support material solution into the formation filling in cracks in the rock, do not play a supporting crack closure due to stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production. Practice has proved that the use of high-alumina proppant hydraulic fracturing wells can increase production by 30-50%, but also to extend the service life of oil and gas wells, a key material in the oil and gas wells in low permeability oil and gas exploration and construction. Products used in deep fracturing, it will be filled to the low permeability fractured rock deposits in high closed Fracturing proppants treatment, the hydrocarbon rock split, play a supporting fissures not because of stress release and closed, thereby maintaining the oil and gas high flow capacity, not only to increase oil and gas production, and can extend the service life of oil and gas wells.
