Description
Technical field
The present invention relates to exploitation of gas hydrates technical field more particularly to the non-diagenesis gas waters of sea-bottom shallow
Close object lifting device.
Background technique
Gas hydrates are also known as " combustible ice ", by based on methane hydrocarbon gas and water in certain temperature, pressure condition
" cage compound " of lower formation, white crystal structure.Gas hydrates especially ocean hydrate is not yet to open at present
A kind of maximum new energy of the reserves of hair, reserves are equivalent to the energy reserves such as coal known to the whole world, oil and natural gas
Twice, but to realize that the effectively controllable business exploitation of hydrate is the problem that the current whole world faces.
The form that is primarily present of hydrate has sandrock-type, sandstone crack type, particulate crack type and dispersing type, and wherein particulate is split
Gap type and distributed hydrate account for the overwhelming majority.So far, the gas hydrates sample acquired by China sea area is
Non- diagenesis gas hydrates, the gas hydrates overwhelming majority that Global Success obtains also is non-diagenesis gas hydrates.
The non-diagenesis gas hydrates of deep water have the characteristics that reserves it is big, it is weak it is cementing, stability is poor, once the temperature of region, pressure
Power condition changes, it is possible to lead to a large amount of decomposition of the non-diagenesis gas hydrates in seabed, gasify and freely discharge, exist
Potential risks.Voltage drop method, heat injection method, chemical inhibitor method and CO in hydrate tradition recovery method2Replacement exploitation method etc.
Method has carried out Short-Term Producing show-how verifying to polar region sandstone and sea area sandstone reservoir gas hydrates, and safety has
Wait further investigate, and there are also very big distances for individual well test yield distance business exploitation thresholding.Therefore, for being stored in seabed table
The exploitation of deep water shallow-layer, weak cementing gas hydrates then needs to consider a kind of completely new exploitation within several meters to 200 meters of layer
Mode.Zhou Shouwei etc. samples situation according to the sampling of world sea area hydrate and China sea area hydrate, and it is shallow to be put forward for the first time deep water
Layer gas hydrates solid state fluidizing production technique, reduces the possible environmental risk of shallow-layer decomposition of hydrate, reaches green
The purpose controllably exploited.But for after shallow-layer hydrate solid state fluidizing, the collection of mixture slurry, hydrate particle and sand grains
Separation, the lifting of hydrate slurry, there is presently no fairly perfect devices.
