摘      要:Sand production is one of the main obstacles restricting gas extraction efficiency and safety from marine natural gas hydrate(NGH)*** migration within the NGH reservoir dominates sand production behaviors,while their relationships were rarely reported,severely constrains quantitative evaluation of sand production *** paper reports the optical observations of solid particle migration and production from micrometer to mesoscopic scales conditioned to gravel packing during depressurization-induced NGH dissociation for the first *** evolutionary modes of sand migration are established based on experimental observations,and its implications on field NGH are comprehensively *** particle migration regimes of local borehole failure,continuous collapse,wormhole expansion,extensive slow deformation,and pore-wall fluidization are proved to occur during *** types of particle migration regimes and their transmission modes during depressurization are predominantly determined by initial hydrate *** contrast,the depressurization mainly dominates the transmission rate of the particle migration ***,both the cumulative mass and the medium grain size of the produced sand decrease linearly with increasing initial methane hydrate(MH)*** gas bubble emission,expansion,and explosion during MH dissociation delay sand migration into the *** the same time,continuous water flow is a requirement for sand production during hydrate dissociation by *** experiments enlighten us that a constitutive model that can illustrate visible particle migration regimes and their transmission modes is urgently needed to bridge numerical simulation and field *** wellbore layout positions or special reservoir treatment shall be important for mitigating sand production tendency during NGH exploitation.
