Description
Technical field
The present invention relates to the quarrying apparatus of a kind of gas hydrates.
Background technology
Gas hydrates are at certain pressure and a kind of solid crystal mass of relatively being formed under low temperature by natural gas and hydrone.In the gas hydrates existed in nature, natural gas is mainly composed of methane.This resource reserve is big, have a very wide distribution, energy density is high, impurity is few, pollution-free.After within 1810, finding gas hydrates and synthetic gas hydrates in 1888 first at laboratory, gas hydrates are studied always and explore by Chinese scholars.Up to now, it has been found that hydrate crystal structure have I, II and H tri-kinds, structure I hydrate ideal molecular formula is 8M 46H2O, in formula, M represents guest molecule.Structure II hydrate ideal molecular formula 24M 136H2O, structure H hydrate ideal molecular formula is 6M 34H2O.Absolutely empty gap does not have under the hypothesis state of guest molecule, the density respectively 796/m of structure I and structure II hydrate3With 786/m3.Clathrate hydrate crystalline density is at 880-900/m3Between, generally light than water.At present, all over the world scientist to the type of gas hydrates and physico-chemical property, naturally compose and deposit and the relation etc. of accumulating condition, resource assessment, exploration and development means and gas hydrates and Global climate change and marine geologic disasters has carried out extensive and fruitful research.Although the reserves of gas hydrates are very abundant, exploitation and the value used and prospect are all fine, but do not realize extensively effective business exploitation at present and utilize, and are mostly exploitation when research exploitation and special gas reservoir.
Trace it to its cause, mainly there is no a set of recovery method that can be widely adopted and obtain effective extraction value all the time.Through the research of scientist, having had some recovery methods, they are voltage drop methods, temperature activation method, inject chemical-agent technique and CO2Displacement method etc., but each method has again its shortcoming.It is the condition that the pressure depositing stratum by reducing gas hydrates to compose breaks its stable existence for voltage drop method, forces it to decompose.The extraction system that only reduces pressure when gas hydrates are positioned near equilibrium boundary just has business extraction value.Being the stratum containing gas hydrates is heated intensification force it to decompose for thermal excitation, heat shock method is maximum has a problem in that heat utilization ratio is low, although recently microwave and Electromagnetic Heating, but but without fundamentally solving the problem that heat utilization efficiency is low.Being destroy the equilibrium condition of gas hydrate synthesis with some special chemical reagent (such as methanol, ethanol, ethylene glycol, saline, calcium chloride etc.) for chemistry extraction system, force it to decompose, the method cost is high and has certain environment to pollute.For CO2Displacement method is by mean of CO2The pressure difference existed during gentle both hydrates steady statue is exploited, and wants CO2Emulsion is applied in actual exploitation, it is necessary to trying every possible means to prepare can stable existence and lower-cost CO2Emulsion.Therefore, from existing recovery method it can be seen that restriction gas hydrates commercial development utilize bottleneck be that how to find effective can when various gas reservoir widely used recovery method.
