In view of the problems of poor development effect, unclear understanding of multi-cluster fracturing equilibrium expansion control and temporary plugging mechanism, and low-cost and high-efficiency fracturing technology system that has not yet been formed in the economic development of normal hydrostatic pressure shale gas，and based on reservoir characteristics and technology development status, low-cost and high-efficiency fracturing technology countermeasures for normal hydrostatic pressure gas are carried out. The results present that low cost, dense clusters, multi-stage temporary plugging, high-strength continuous pumping sand and increasing ESRV are the directions for continuous optimization of high-efficiency fracturing technology for normal hydrostatic pressure shale gas. Optimizing fracturing cost composition and applying new technologies are effective ways to reduce costs and enhancing production. The cluster spacing has a great influence on the fracturing effect, and the recommended range is 5-10 m. Plugging in the middle and early stage and increasing the plugging times can improve the temporary plugging effect. The higher the stress difference, the more times the temporary plugging is required to increase SRV. To improve the plugging effect, the beneficial time for plugging agent injection is in the middle of the construction for reservoirs with natural fractures density more than 0.5 fracture/m, while the beneficial time is in the early stage of construction for reservoirs with natural fractures density less than 0.5 fracture/m. Temporary plugging agent with particle size smaller than 40/70 mesh, fracturing fluid with viscosity greater than 12mPa·s, and pumping rate greater than 12m^³/min with volume fraction less than 0.1 can enhance plugging fracturing effect. The quartz sand combination of 140/200 mesh (10%) + 70/140 mesh (30%) + 40/70 mesh (60%) and the ratio of sand and liquid greater than 7% are recommended to reduce the cost and to increase the production.
