Simulating method of special oil sludge in oil field

The invention provides a simulating method of special oil sludge in oil field. The simulating method comprises the steps of preparing simulating mineralized water in the oil filed, adding oil-displacing polymer used for the oil field to prepare a polymer solution, and conducting degradation and shearing treatment on the polymer solution; adding crude oil subjected to field dehydration in the oil field and rocks and minerals in the oil filed into the polymer solution being subjected to the degradation and the shearing; adding an inorganic cationic type flocculating agent and an organic cationic type flocculating agent into mixed liquid of oil, water and minerals respectively; putting a sticky flocculant layer aqueous solution into a high temperature oven and a minitype electric dehydrator successively to be subjected to treatment so as to obtain the simulated special oil sludge. According to the simulating method of the special oil sludge in the oil field, simulations of oil sludge of different types and the special oil sludge in the oil filed under different treatment conditions are achieved, the simulating method is simple and reliable, the treatment conditions are flexible, and the simulating method can be used for applicability evaluations of all kinds of oil sludge treatment technologies and analysis of the cause and prevention and treatment of the special oil sludge in the oil filed.
