The invention discloses a hydrate breaking multiphase flow simulation detection experimental device based on natural gas hydrate solid fluidization exploitation. The hydrate breaking multiphase flow simulation detection experimental device comprises a multiphase flow configuration conveying control unit, an image video acquisition unit and an image video processing unit, the image video acquisition unit is connected with the multiphase flow configuration conveying control unit through a pipeline, and the multiphase flow configuration conveying control unit is used for configuring the hydrate to-be-detected samples under different conditions and conveying the to-be-detected samples to the image video acquisition unit; the image and video acquisition unit is used for acquiring the images andvideos of the hydrate to-be-detected samples of different conditions conveyed by the multiphase flow configuration conveying control unit, and the image and video processing unit processes the imagesand videos acquired from the image and video acquisition unit. According to the invention, the state of the multiphase flow after hydrate crushing can be simulated and detected, and the multiphase flow picture video after hydrate crushing is detected by using the image video acquisition unit.
Description
technical field [0001] The invention relates to a multiphase flow experimental detection device, in particular to a multiphase flow simulation detection experimental device based on hydrate fragmentation in solid-state fluidized exploitation of natural gas hydrate. Background technique [0002] Natural gas hydrate (hereinafter referred to as hydrate) refers to a cage-like crystal substance formed by natural gas and water at a certain temperature and pressure. It can burn when exposed to fire, commonly known as "combustible ice". Hydrate mainly occurs in continental permafrost regions, polar regions, and sea sediments with a water depth greater than 300m. Its rich energy reserves have attracted global attention. [0003] The occurrence states of natural gas hydrate samples obtained so far can be divided into sandstone type, sandstone fracture type, fine-grained fracture type and dispersed type. Compared with conventional oil and gas reservoirs, marine gas hydrate occurrence ...
