Multi-stage hydraulic fracturing in horizontal wells has been more widely adopted for shale gas development. Fracturing cost control is the key point to guarantee shale gas development benefit. Currently, valuation standard of fracturing in shale gas large horizontal well has not been introduced in China. Based on conventional gas fracturing standard, which cost is determined by scale increasing, fracturing cost in shale gas is fairly high and is inconformity with the practical situation. This paper analyzes the characteristics of the horizontal wells fracturing and differences of 8 technical and economic parameters of the fracturing engineering in conventional gas. The advantages and disadvantages and the application scope of three models, bill of quantities, quota valuation and total charge, are compared. And these models have been commonly used in fracturing engineering valuation at home and abroad. Valuation methods of combining on bill of quantities and quota valuation are put forward which are suitable for the present stage of shale gas development. The key valuation parameters of fracturing in shale gas horizontal wells are studied. Four control measures about the technical research, the standard establishment, the design optimization and the market competition are discussed. The research has a positive significance to speed up the shale gas resources development and improve the investment efficiency.
