There are many sand and shale interbed in Daniudi gas field. Although the horizontal well exploitation can realize the maximum utilization of the single layer reserves, it is impossible to exploit several reservoirs in the longitudinal direction. A systematical and significant influencing the Daniudi gas field exploitation technology called layers penetration fracturing that between the pay zone He-1 and Shan-2 has been developed by associate with the characteristic of pay zone. The treatment parameter such as discharging rate and fluid viscosity also researched for the aim of proposing the treatment advice and optimal method in different conditions, in order to form the penetration principle and a technique that could identify controllable factors. Associated with the precise single well stress explanation results and well temperature monitoring, the layers penetration model and principle's reliability have been verified, which presented the steerable layers penetration fracturing treatment and parameter optimization method.
