Abstract: In view of the characteristics of horizontal well reservoirs in the national shale gas demonstration area of the Fuling shale gas field, combined with casing cementing and completion methods, in order to maximize the effective transformation volume, the complexity of the crack within the volume is maximized. Fracturing technology, low-cost and high-efficiency material system, and back-discharge liquid reuse technology have formed a set of high-efficiency fracturing technology suitable for the horizontal wells of Fuling shale gas. The fracturing process has realized the target of complex fracture network. The high-efficiency and low-cost drag reduction hydraulic fracturing fluid system meets the requirements of continuous compounding construction, and the cost is reduced by more than 20% compared with the foreign water-reducing water system. The on-site test drag reduction rate is as high as 74.5%, and the return-discharge liquid reuse technology realizes zero liquid emission. As of December 2017, the integrated technology has accumulated 330 wells on site, fracturing 5 300 segments, with the process success rate of 97% and the average unobstructed flow of 385 000 cubic meter per day. The effect of increasing production and increasing gas is significant.
