Abstract: In order to solve the problem of refracturing well selection in shale gas wells, the evaluation indexes such as the porous elastic stress steering coefficient, unit pressure drop yield, pressure coefficient, gas reservoir quality index and normalized pseudo-production decline rate were introduced for geological features of shale gas wells such as reservoir fault development, curvature and fracture distribution. The evaluation model of refracturing well selection for shale gas wells was established, and the candidate wells for refracturing were selected. At the same time, the technology of temporary plugging diverting technology in refracturing wells was clarified, and the design parameters of the refracturing process were optimized. This model was applied to the refracturing of Fuling shale gas well, and the optimized candidate wells can be retrofit. The daily output was increased by 5-6 times in the early stage of operation, which provided a reference for the long-term and efficient development of Fuling shale gas field.

Key words: shale gas well, refracturing, well selection, fracturing technique, temporary plugging diverting
