Abstract

The invention belongs to the technical field of water treatment, and particularly relates to a sterilizing stripper dedicated for oilfield injection water and a preparation method thereof. The sterilizing stripper dedicated for the oilfield injection water is characterized by compounding the following materials in percentage by weight: 15 to 35 percent of tetrakis hydroxymetyl phosphonium sulfuric, 10 to 35 percent of dodecyl dimethyl benzyl ammonium chloride, 0.5 to 1.0 percent of sodium dioctylsulfosuccinate, and the balance of deionized water. The preparation method comprises the followingsteps: adding the deionized water into a reaction kettle; and adding the tetrakis hydroxymetyl phosphonium sulfuric, the dodecyl dimethyl benzyl ammonium chloride and the sodium dioctylsulfosuccinate, and stirring for 40 to 50 minutes at normal temperature. By the method, the stripping performance of the sterilizing stripper and the killing performance to bacteria, particularly sulfate reducing bacteria, are improved; the sterilizing stripper has strong sterilization capability, good penetration and remarkable stripping effect; and the preparation process is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a special bactericidal stripping agent for oilfield reinjection water and a preparation method thereof. Background technique [0002] Oil field injection water contains high oil pollution, suspended solids and sulfides, high COD, complex composition, poor water quality, serious bacterial reproduction and slime growth, many sulfate-reducing bacteria, and great harm. Currently used bactericidal stripping agents have unsatisfactory stripping effects, and the killing rate of sulfate-reducing bacteria is on the low side. For this reason, our company has carried out a series of research and experiments on the actual situation of oilfield reinjection water, developed and mass-produced a special stripping fungicide suitable for oilfield reinjection water with good effect. Contents of the invention [0003] The technical problem to be solved by the present invention...
