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: 1.2 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: 1.8 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

SINOPSIS

The multijet bit is a critical component of radial horizontal drilling technology, which not only has to break the rocks but also produce forward, self-propelled force to the high-pressure hose. The influence of structural parameters and hydraulic parameters on the rock-breaking efficiency of multijet bits was studied. Results show that the greater the number of holes of the jet bit, the more round the form of the borehole will be. As the lateral orifice diffusion angle increases, the rock-breaking efficiency first increases and then decreases. The working principle of the multijet bit was investigated and the mechanical control equations of the jet bit were established based on the momentum flux method. Furthermore, the impact of bottom hole pressure drop generated by a back jet on self-propelled force was also studied. From the experimental results, the flow rate, forward-reverse flow ratio of the jet bit, and the wellbore diameter are primary factors influencing the self-propelled force. Under experimental conditions, the self-propelled force increases with the increase of flow rate. With the same flow rate, the self-propelled force increases when the forward-reverse flow ratio decreases. The self-propelled force first increases and then decreases as the wellbore diameter increases. The self-propelled force ranges from 67.8 to 228.1 N.
