The carbon dioxide foam injecting device solves the problem of frozen blocking in the carbon dioxide foam oil-displacement process and effectively ensures the foaming performance of a carbon dioxide foam system.
Description
Technical field
The present invention relates to the plant equipment on a kind of oilfield, particularly relate to a kind of oil well carbon dioxide foaming injection device.
Background technology
In petroleum industry, more early stage foam maker is mainly used in enriched in foam technique, along with to the progressively research of foam on petroleum drilling and mining field, China has carried out utilizing aerated fluid to carry out profile control and water plugging in most produce oil base, acidifying strata, well cementing of cement, pressure break, sand-flushing, drilling well, the field test research such as water pumping gas production and foam steam flooding, and obtain good effect, foam is a kind of compressible gas-liquid mixture, using foam maker from theory analysis from the past, the place also come with some shortcomings, larger pressure can not be born, the etching problem do not considered in application in oil-gas field development, the low-density aerated fluid that its structure design produces can not meet the needs that Oil Field is produced completely, foam quality is low, blowing agent can not mix fully with carbon dioxide liquid, can not because of reality need temperature adjustment etc. is carried out to it, especially carbon dioxide foaming drive injection well mouth CO
2-20 DEG C to be absorbed heat by liquid state and cause the situation of foaming agent frozen block surface line and pit shaft in gaseous state conversion process.
