摘要：Shale gas reservoir at the outer edge of Sichuan basin belongs to normal pressure shale gas reservoir. In the analysis of the difference between the current and the pressure shale gas drilling, the technical measures to reduce the cost of drilling, the design of the well, the borehole trajectory, the drilling, the drilling fluid and the cementing process, the design of the three shafts, the design of the structure of the shaft, the design of the two dimensions of the well, the design of the two dimensions, the design of the orbital trajectory of the shafts, using the spin guide technology to control the orbital trajectories of the two shafts, the low-oil, and the optimal production of the concrete and the production of the drilling and the drilling costs, the technology and the measures, to provide the technical support for the economical and efficient development of the natural gas in the Sichuan basin.
