摘要：Simultaneous fracturing and zipper fracturing of horizontal wells has rapidly evolved to the development of unconventional oil and gas. The fracture interference when multiple fractures propagate needs further study. This paper experimentally investigates the sequential propagation of multiple fractures in horizontal wells. Eight artificial rocks, each with dimensions of 400 mm ×400 mm ×400 mm and equipped with two horizontal wells, are sequentially fractured. The effects of the horizontal stress difference, the fracturing sequence, and the arrangement of perforations were discussed. The results show that previously created fractures exhibit a noticeable attraction effect on laterally created fractures, with horizontal stress difference emerging as a pivotal factor. A lower horizontal stress difference strengthens the attraction effect of previously created fractures on laterally created fractures. During staggered fracturing, laterally created fractures are simultaneously affected by the attraction effect of previously created fractures and the extrusion effect of the adjacent propagating fracture. Staggered fracturing of multiple perforation clusters proves effective in enhancing the stimulation of perforation clusters and achieving balanced fracture initiation and propagation. This research yields valuable insights into fracture propagation, guiding and optimizing the design and implementation of multiple staged fracturing in horizontal wells.
