“…The development of shale gas horizontal well technology has led to staged fracturing technology in horizontal wells. In longer horizontal well sections, staged fracturing technology is often used for stimulation treatment, and can be divided into the staged fracturing patterns of the pump-down bridge plug, "sleeve + packer", cementing sleeve, and hydraulic jet of coiled tubing [5]- [8]. To improve the efficiency of shale gas development, the "multi-well pad" fracturing pattern is adopted in the development of horizontal well fracturing technology [6], [9].…”

In the development of the Fuling shale gas field, for the first time, Well R9-2 was selected for a test of time-phased staged fracturing and refracturing treatments to study the effectiveness of fracturing at each stage for a novel development approach exploration. This paper introduces the design of the experiments, analyzes the results, and provides a follow-up evaluation of the entire development process. As of 9 August 2020, the well had gone through three phases of development. Phase Ⅰ: time-phased staged fracturing and development for Stages 1-2, 3-4, 5-6, and co-development for Stages 1-6; Phase Ⅱ: Stages 1-6 were developed once more after refracturing; Phase Ⅲ: sealing the sections in Stages 1-6, then fracturing and development of Stages 7-19. Pressure build-up tests were conducted during the development of Stages 1-2 and 3-4, and gas production profile logging and microseismic monitoring were performed during the co-development of Stages 1-6. The results show that the combination of time-phased staged fracturing and refracturing treatments can fracture each stage more effectively. The pressure build-up test can effectively obtain the reservoir parameters of developed shale gas wells. The potential of refracturing treatment in a developed well can be identified from the gas production profile logging and microseismic monitoring. The findings are of this study productive for enhanced shale gas recovery; the combined pattern of time-phased staged fracturing and refracturing acts as a direct guideline to future shale gas production.INDEX TERMS Shale gas development, time-phased staged fracturing, refracturing, pressure build-up test, gas production profile logging, Fuling shale gas field
