Abstract:A hydraulic fracture extension model was established, an extension criterion
and an extension mode of hydraulic fracture were analyzed, and the
theoretical prediction was compared with the practical results, a good
agreement was observed. Furthermore, the direction of hydraulic fracture
extension was also discussed, the results showed that the hydraulic fracture
propagates from the cut to the bedding plane, forming a complex mixture of
longitudinal and transverse fractures fracture network. T… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
