Simulation has been manufactured in telephone-moving.It is wherein to borrow oceanography " interphase mass transfer to the simulation of the intermediate zone between zone of saturation and unsaturated zone
Two-way Theoretical Resistance " (by the model as gas exchanges between ocean and atmosphere).If with this theoretical explanation dive
The migration situation of the outer gas of the water surface, since the cementation of deposit or soil can generate resistance, this model to gas migration
There can be some uncertainties when explaining the migration behavior of gas at underground latent water face.In addition, unsaturated zone top hydro carbons oxygen
Change bacterium be to the degradation rate of lighter hydrocarbons it is assumed that and by known area actual measurement inverting method acquire, there is also uncertainties.Actually survey
In spy, it has been found that some variations for being difficult to explain occur phreatic surface for hydrocarbon component up and down, such as the concentration of ethane under phreatic surface
Greater than the concentration of propane, and the concentration of ethane is then less than the concentration of propane on phreatic surface, is simply interpreted as exchange interaction and is difficult to
Explain its true cause.
The above problem would interfere with the understanding to lighter hydrocarbons Micro blazed-grating mechanism, influence the application effect of hydrocarbon geochemical exploration.In decades,
Since the difficulty that the complexity and experimental provision of the mechanism of the vertical Micro blazed-grating of lighter hydrocarbons are built is big, the precision limitation of detection technique
Deng the above problem never has the support of reliable simulated experiment result.And the vertical micro- infiltration of simulation lighter hydrocarbons done both at home and abroad
The device of leakage solves the problems, such as that specific aim is stronger, there is no for lighter hydrocarbons from deep zone of saturation, unsaturated zone Micro blazed-grating to earth's surface
Mechanism carries out simulation experiment study.
Therefore, how to solve, which there is no, carries out for lighter hydrocarbons from the mechanism of deep zone of saturation, unsaturated zone Micro blazed-grating to earth's surface
The problem of simulation experiment study is those skilled in the art's technical issues that need to address.
