[0013] Table 1
[0014]
[0015] Apply the present invention to test the thin oil treatment station sludge of a certain operation area in Xinjiang oilfield: take by weighing sodium dodecylbenzenesulfonate 5g, sodium dodecanoate 5g, Span (60) 8g, sodium hydroxide 10g, water 72g . First add sodium dodecylbenzenesulfonate and sodium dodecanoate into the reaction kettle, add water and stir for 10 minutes, control the temperature at 50°C, then add sodium hydroxide, stir for 5 minutes, then add Span (60), continue stirring After 10 minutes, an environment-friendly treatment agent for oily sludge in oilfields can be prepared. Then mix 50g of washing agent with 100ml of 50°C hot water, then add 0.5ml of washing agent, stir for 10 minutes at a speed of 300 rpm, and let it stand for 1 hour. The s...
