Abstract
The invention discloses a technique of a foam flooding for petroleum extraction, which comprises the following steps: 1) on the basis of the mass percent of the total foam flooding, adding 0.4-0.6% of secondary alkane sulfonate and 2.3-2.8% of sodium carbonate into a mixing pump, uniformly mixing at 60-70 DEG C, adding a bactericide, and filtering to obtain a component A; and 2) mixing water vapor and carbon dioxide in a mass ratio of 4:3 to obtain a component B. The preparation method is simple; and the prepared foam flooding has favorable displacement effect.
Description
Technical field
The invention belongs to oil production field of chemicals, particularly, relate to a kind of technique preparing oil production foam flooding.
Background technology
Oil, as important Mineral resources, is of great rarity.In oil production process, usually dividing three phases for improving the recovery ratio of oil: primary oil recovery, relying on that the natural energy on stratum is fuel-displaced, recovery ratio is below 30%; Secondary oil recovery, adopt water filling, air insufflation techiques fuel-displaced with supplementary oil reservoir energy, recovery ratio can be increased to 40-50%; Tertiary oil recovery, utilize the strengthening mining such as physical chemistry and biology remaining reserves, recovery ratio can be increased to about 80-85%.Usually need to adopt foam flooding to improve tar productivity in tertiary phase, and the effect of the preparation method of foam flooding to its displacement of reservoir oil has certain influence.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of technique preparing oil production foam flooding, makes the oil displacement efficiency of the foam flooding obtained good.
The present invention's adopted technical scheme that solves the problem is:
The technique of preparation oil production foam flooding, comprises the following steps:
1) in total foam flooding massfraction for 100%, by 0.4-0.6% two generation alkane sulfonate and the sodium carbonate of 2.3-2.8% join in mixing pump, mix at the temperature of 60-70 DEG C, add sterilant, after filtration, obtain component A;
2) be that the ratio of 4:3 mixes with mass ratio by water vapour and carbonic acid gas, obtain B component.
During use, inject component A and B component continuously to produce foam to oil-bearing formation.
To sum up, the invention has the beneficial effects as follows: the preparation method of foam flooding of the present invention is simple and oil displacement efficiency that the is foam flooding obtained is good.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.

The technique of preparation oil production foam flooding, comprises the following steps:
1) in total foam flooding massfraction for 100%, by 0.4% two generation alkane sulfonate and 2.3% sodium carbonate join in mixing pump, mix at the temperature of 60-70 DEG C, add sterilant, after filtration, obtain component A;
2) be that the ratio of 4:3 mixes with mass ratio by water vapour and carbonic acid gas, obtain B component.
During use, inject component A and B component continuously to produce foam to oil-bearing formation.
To sum up, the oil displacement efficiency of the foam flooding that the preparation method of foam flooding of the present invention is simple and obtained is good.
As mentioned above, the present invention can be realized preferably.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention; according to technical spirit of the present invention; within the spirit and principles in the present invention; the any simple amendment that above embodiment is done, equivalently replace and improve, within the protection domain all still belonging to technical solution of the present invention.
