1080 seconds；Under identical heating time, as heating time be 1000 seconds when, when being only injected into steam, 6 temperature of 2# temperature sensors
It it is 29 DEG C, when diethanol amine chemical agent is with steam mixed injection, 6 temperature of 2# temperature sensors is 75.22 DEG C.
Fig. 6, Fig. 7 the result shows that, section, especially later stage in different times, 1# temperature sensors 5 and 2# temperature sensors
The mixed vapour temperature that the water and diethanol amine of 6 displays are formed, in rock core system heating temperature much larger than either pure steam heating temperature
Degree.Therefore, the mixed vapour that water is formed, which is added, in diethanol amine can improve that steam drives or steam soak involves range.
Experimental example 4：It is 1 by weight ratio：After 1 N methyldiethanol amine and diethanol amine medicament is mixed with water vapour, when
The temperature of steam generator 3 reach 300 DEG C, pressure driving device is opened when reaching 5MPa, measure different time sections 1# temperature and pass
The temperature of sensor 5 and 2# degree sensors, and with the pure water vapor without N methyldiethanol amine and diethanol amine confection into
Row comparison, comparing result are as shown in Figure 8, Figure 9.
In Fig. 8, when being only injected into steam, it is 820 seconds that when 100 DEG C of 5 displays temperature of 1# temperature sensors, which needs heating time, N-
With after water vapour mixed injection, when 100 DEG C of 5 displays temperature of 1# temperature sensors, needs for methyl diethanolamine and diethanol amine medicament
Heating time is 610 seconds；Under identical heating time, as heating time be 1000 seconds when, when being only injected into steam, 1# temperature pass
5 temperature of sensor is 120 DEG C, when N methyldiethanol amine and diethanol amine medicament are with steam mixed injection, 5 temperature of 1# temperature sensors
Degree is 159.3 DEG C.
In Fig. 9, when being only injected into steam, it is 1380 seconds that when 100 DEG C of 6 displays temperature of 2# temperature sensors, which needs heating time,
After N methyldiethanol amine and diethanol amine mixed chemical medicament and water vapour mixed injection, 6 displays temperature of 2# temperature sensors
It is 1100 seconds that heating time is needed at 100 DEG C；Under identical heating time, as heating time be 1000 seconds when, be only injected into steaming
When vapour, 6 temperature of 2# temperature sensors is 29 DEG C, and N methyldiethanol amine and diethanol amine mixed chemical medicament mix note with steam
Fashionable, 6 temperature of 2# temperature sensors is 73.92 DEG C.
Fig. 8, Fig. 9 the result shows that, section, especially later stage in different times, 1# temperature sensors 5 and 2# temperature sensors
The mixed vapour temperature that water, N methyldiethanol amine and the diethanol amine confection of 6 displays are formed heats temperature in rock core system
Degree is much larger than either pure steam heating temperature.Therefore the mixing that water is formed is added in N methyldiethanol amine and diethanol amine confection
Steam can also improve that steam drives or steam soak involves range.
In conclusion the present invention passes through the raising steam drive of addition super-viscous oil or steam during steam drive or steam soak
The inorganic agent for the efficiency of heating surface of handling up, can improve steam drive or steam soak involve range, improve steam in oil reservoir plus
The thermal efficiency, to improve super-viscous oil steam injection development steam drive or steam soak recovery ratio.
The above technical characteristic constitutes the embodiment of the present invention, can basis with stronger adaptability and implementation result
Actual needs increases and decreases non-essential technical characteristic, to meet the needs of different situations.
