Description
Technical field
The present invention relates to Oil and Natural Gas Engineering major teaching experimentation apparatus, especially one can intuitional instruction and easily
In the extraneous factor operated on Water Soluble Gas Migration impact analogue experiment installation.
Background technology
Natural gas is generating, migrating and is having all the time in Filling process the participation of formation water, and we are generally by this process letter
It is referred to as Water Soluble Gas Migration.Water Soluble Gas Migration is to need specific condition, and the most particularly important one is formation water
This factor of the dissolubility of middle natural gas.Research shows, under underground high temperature, high pressure conditions, and natural gas dissolubility in water
Very big, and change with temperature, pressure and the change of salinity.In deep reservoir, with the presence of a large amount of corrosion cavities,
Also with the presence of some cracks, and reservoir is the most aqueous, and Water Soluble Gas keeps significant contribution, the gas field trap of Weiyuan, the Sichuan Basin to one-tenth
After being formed at Early Himalaya, before the hydrocarbon source rock anger phase is Early Himalaya.Stop due to structure lifting hydrocarbon source rock after trap forming
Evolution cannot supply to trap, but equally forms Gas Fields, here it is what Water Soluble Gas brought up.
At present, the scholar of research Water Soluble Gas Migration is a lot, and temperature, pressure and salinity are to Water Soluble Gas Migration shadow
Ringing huge, temperature, pressure and salinity are referred to as extraneous factor, and the conclusion drawn is as follows:
The impact that temperature is dissolved in water to natural gas is complex, and when temperature is less than 80 DEG C, gas solubility is with temperature liter
High and be gradually reduced；When temperature is more than 80 DEG C, gas solubility raises with temperature and is gradually increased；
Pressure is dissolved in the impact of water to natural gas, and gas solubility increases with pressure and increases；
Salinity is dissolved in the impact of water to natural gas, and salinity is the highest, and gas solubility is the least；Salinity is the lowest, natural
Gas dissolubility is the biggest.But, there is no the most in the industry temperature, pressure and salinity and natural gas be dissolved in the associated analog of water impact
Assay device, this makes the teacher of Oil and Natural Gas Engineering specialty when to students give lessons, can only start with from theory, it is impossible to straight
That sees presents temperature, pressure and salinity to student natural gas is dissolved in the impact of water.
Design a kind of extraneous factor to Water Soluble Gas Migration impact analogue experiment installation to Oil and Natural Gas Engineering
