Field.
2nd, background technology
Hot water flooding is a kind of process of hot water and cold water immiscible displacement crude oil, and heat enthalpy value is relatively low, with steam drive compared with
Had a clear superiority in terms of fluidity control and expansion swept volume, ground surface works are simple.Consuming little energy is driven than steam, is gulped down than steam
It is big to tell energy offer amplitude, (energy offer amplitude：Steam drives ＞ hot water flooding ＞ steam soaks), than conventional water drive oil and water mobility ratio
Improve substantially, can be as viscous oil field operated by steam or the follow-up mining type of steam soak.
Hot water flooding is a kind of effective technical way for improving recovery factor of heavy oil reservoir, but there is also certain technology limitation.
Hot water is lower than cold water viscosity, is more easy to that water breakthrough occurs in heterogeneous reservoir, need to be with the supporting technology phase such as profile control, transfer drive, chemical flooding
With reference to the purpose that increases substantially oil recovery could be realized.
At present, the water filling temperature of hot water flooding+chemical flooding well head is less than the maximum temperature (generally 80 that water injecting pump can bear
DEG C), well head water filling temperature is low, does not reach the optimal water filling temperature of hot water flooding+chemical flooding, DeGrain, and oil recovery efficiency is low.This
Invention then provides a kind of good method to solve this problem, can meet that the optimal water filling temperature of hot water flooding+chemical flooding is big
In the operating mode for the maximum temperature that water injecting pump can be born.
3rd, the content of the invention
