| titleOfInvention | High efficiency anti-magnesium ions oil displacement agent and its preparation method |
| abstract | The invention relates to a high efficiency anti-magnesium ions oil displacement agent and its preparation method, which mainly solves the problems that poor oil displacement efficiency of the surfactant-containing oil displacement agent under the high temperature and high salinity, high usage concentration, and the corrosion and scale depositing of stratum and oil well caused by the presence of alkali in the ternary combination flooding in the prior art. The high efficiency anti-magnesium ions oil displacement agent comprises the following components by mass percent: (1) 0.01-5.0% of N,N-dual fat acyl diamine dimethyl propionic acid polyoxyethylene ether disulfonate; (2) 0.01-3.0% of polymer; (3) 92.0-99.98% of injected water; wherein a molecule general formula in the component (1) is: in the formula, R1 is C9-C17 alkyl, R2 is C2-C6 alkyl, n is an adduct number of an ethoxy group EO, the data range is any integer in 2-7; M is selected from any one metal ion of potassium, sodium or lithium; a polymer is selected from one or two of ultrahigh molecular weight anionic polyacrylamide, modified polyacrylamide or xanthan gum; and oil field injected water is selected for water. The technical scheme better solves the problems, and can be applied to the production of tertiary oil recovery in oil fields. |
