Abstract
This invention relates the oil-displacing agent - the multi-speed catalysis phenol formaldehyde resin gel which is used elevating the oil recovery efficiency in oil development, and also relates its use. It makes up of the following constituents according to the ratio of weight: hydrolyzed polyacry lamide 0.06%-0.6%, phenol 0.06%-0.12%, formaldehyde 0.06%-0.12 %,and/or catalyzer 0.01%-0.06%, and water. The multi-speed catalysis phenol formaldehyde resin gel can be used as oil-displacing agent or bulkhead agent, and can also used as reservoir of the middle or low infiltration sandrock with the temperature above 80DEG C in oil field. It can be separated into three speeds to control the time of gel formation according to the requirements of oil field. So it can satisfy the different function of displacing oil and blocking up water. The cost is low when it used as oil-displacing agent and the time of gel formation can be shortened violently when it used as bulkhead agent. The mission success rate is increased and the stabilization time is above 6 months.
Description
Technical field
The present invention relates to be used in a kind of oil development oil-displacing agent multi-speed catalysed phenolic resin gel that improves oil recovery and uses thereof.
Background technology
(1) hydro-polyacrylamide and P-F form the water-blocking operation that phenolic resin gel is used for the oil field high-temperature oil reservoir, do not use as oil-displacing agent.
(2) time and the temperature correlation of P-F-polymer formation gel, temperature is high more, and the time that forms gel shortens, oil reservoir for about 80 ℃, P-F-hydro-polyacrylamide forms the time of gel more than 120h, forms the overlong time of gel, is unfavorable for rig-site utilization.
(3) hydro-polyacrylamide of past research and P-F form phenolic resin gel polymer concentration height, cost height.
(4) (below 40 ℃) are solid under the phenol normal temperature, have the difficulty of the dosing of construction.
Summary of the invention
The phenolic resin gel that the objective of the invention is the hydro-polyacrylamide that is used for oil field high-temperature oil reservoir water-blocking operation, phenol and formaldehyde are formed is used for the oil field high-temperature oil reservoir as oil-displacing agent and recovers the oil through improving, and improves oil recovery; According to the needs of oil-displacing agent, work out multi-speed catalysed phenolic aldehyde gel flooding system, the time that forms weak gel is shortened in the 24h.
The technical program is achieved in that
At hydro-polyacrylamide, add single component or the gelatigenous catalyzer of multi-component acceleration in phenol and the formaldehyde systems, can be used as the needs of oil field oil-displacing agent or plugging agent, adjust the time that forms gel, catalyzer comprises bases or the Polyphenols chemicals except that phenol, as oxalic acid, sodium hydroxide, sodium bicarbonate, potassium hydroxide, the letter dihydroxy-benzene, chemicals such as diphenol or polyphenol, single speed catalysis can be wherein any, multi-speed catalysed can be two or three mixture wherein, for improving the calcium of system, the ability of anti-bivalent ions high salinity such as magnesium, polyacrylamide can be selected: anionic property, compound ion, nonionic, system can form the displacement of reservoir oil or water blockoff gel in the oil-field water of salinity 8%.
Phenolic resin gel is made oil-displacing agent, presses following weight percent prescription:
Hydro-polyacrylamide 0.06%～0.6%,
Phenol 0.06%～0.12%,
Formaldehyde 0.06%～0.12%,
And/or catalyzer 0.01%～0.06%,
Its surplus is a water.
Using method:
The dissolving hydro-polyacrylamide directly adds phenol, formaldehyde and catalyzer in the container of solvent hydro-polyacrylamide then earlier, after stirring, injects well or oil well with polymer-injecting pump.
This multi-speed catalysed phenolic resin gel uses as oil-displacing agent, Xinjiang Oilfield more than 80 ℃ in, the low infiltration sandrock oil reservoir was promoted the use of 4 years, use two in oil reservoir, increase oil more than 5000 tons, stable yields to the oil field plays an important role, increased the functions of use of polyacrylamide and P-F gelling system, the time of dividing the gel of three speed control formation according to the needs in oil field, satisfy the needs of the difference in functionality of the displacement of reservoir oil and water blockoff, low as the oil-displacing agent use cost, use as plugging agent, the time that forms gel significantly shortens, improve success ratio, be used for the high-temperature oil reservoir more than 80 ℃, steady time is more than 6 months.
