• Abstract: Since the key factors of shale gas development are Estimated Ultimate Recovery (EUR) and single well engineering cost, keeping the single well engineering cost decreasing and benefit-increasing becomes one of the most effective measures to realize high-quality development of shale gas. The high-efficiency development model of shale gas can be summed up as “horizontal well platform + super large scale fracturing + industrialized operation + integrated management”, and the main contents of the four aspects are analyzed. Three main closelyrelated problems of shale gas development in the Sichuan-Chongqing area are discussed: unscientific valuation methods of drilling engineering, unreasonable allocation of resources and insufficient incentive measures. The revolutionary cost-decreasing and benefit-increasing matching measures – “three unifications” – are therefore put forward: the unification of engineering valuation methods, the unification of resource allocation, and the unification of incentive measures; The strong policies supporting matching measures – “three guarantees” – are proposed: the guarantee of land use, the guarantee of resource sharing, and the guarantee of the gas price; The overall high-quality development objectives – “three promotions” – are expected: overall promotion of production efficiency, overall promotion of management level, and overall promotion of whole benefits.
