Abstract

Using Daqing natural sand packed tubular model, the length is 20 cm, 50 cm and 100 cm, and the permeability was (343~482)ž10-3 m2, the injection rate is 1m/d and the experiment temperature is 45 , by the experiment of dynamic adsorption, studying the interfacial tension changes and viscosity changes of the produced liquid after weak alkali-mahogany sulfonate-polymer flood and absorb to the sand packed tubular model with oil or without oil. Experimental results show that: The mahogany sulfonate ternary system, under the condition of sand packed tubular model without oil, the adsorption makes the front of surfactant to migrate in the way of piston-like movement. When the residual oil exists or flows through a smaller distance (0.2 m), the adsorption makes the front of surfactant to migrate in the way of the non-piston-like movement; When the injection volume of the mahogany sulfonate ternary system reaches to 5.1~8.0 PV, the interfacial tension of produced liquid reaches to the ultra-low value, the quantity of dynamic saturated adsorption of mahogany sulfonate ternary system is 3.41~5.13 mg/g; In the sand packed tubular model, after the injection PV of the mahogany sulfonate ternary system reaches to the 1, the produced liquid flows stably in the outlet and contains polymer with a certain viscosity.
