The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.5 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00018 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.42 SJR: 0.217 SNIP: 0.362 CiteScore™:: 2.3 H-Index: 19

RÉSUMÉ

In naturally fractured cavernous carbonates, hydraulic fracture propagation behavior is influenced by natural fractures and cavities; for example, fracture turning or generation of multiple fractures. In this paper, we studied the hydraulic fracturing propagation behavior of naturally fractured cavernous carbonates. Based on the governing equations of fluid/solid coupling in porous medium and the theory of damage mechanics, a finite-element computing model was developed to simulate hydraulic fracture propagation with the effect of natural fractures and cavities. Based on the model, extensive numerical simulations were conducted to investigate fracture propagation behavior. The results show that natural fractures, cavities, and hydraulic fractures change the orientation and magnitude of the horizontal principal stress. The change in the horizontal principal stress and the low residual tensile strength of natural fractures are the main reasons causing turning of the hydraulic fracture. Turning of the hydraulic fracture is determined not only by the intersection angle between the natural fracture and the maximum horizontal principal stress, residual tensile strength, and friction coefficient of natural fractures, but also by the length of the natural fractures, diameter of the cavities, and pump rate. Multiple hydraulic fractures may be generated when a hydraulic fracture enters into a cavity with multiple natural fractures connected to the cavity face. The hydraulic fracture width reduces after turning. The reduction extent depends on the intersection angle between the natural fractures and the maximum horizontal principal stress as well as the difference between the two horizontal principal stresses. The width of hydraulic fracture decreases sharply when the hydraulic fracture enters into a cavity. The downhole pressure increases when the hydraulic fracture meets a natural fracture or a fractured cavity and turns into the natural fracture.
