So the new active gelled acid system is of high popularization value and good application prospect, and plays a positive role to improve the acid modification effect of the reservoir.Ībstract: Aiming at the design goal of the highest efficiency of the electric submersible pump of polymer flooding and basing on the coordination of the production system of the electric submersible pump well of polymer flooding and taking oil well productivity and parameters of electric submersible pump (displacement, lift, power) of the electric submersible pump as the design parameters, a mathematical model of the optimization design method for the production parameters of the electric submersible pump well of polymer flooding using the nodal system analysis method was established, and through the mathematical model mentioned above, the optimization design method for the production parameters of the electric submersible pump well of polymer flooding was given. Practice shows that the acid system is adaptive to different reservoirs, such as sandstone and limestone, and after fracturing by taking it, the production or injection capacity of single well is greatly improved. In addition, field test showed that the construction friction of the new acid system is 40%~60% of clear water, so it can be used for the operation with large displacement. Due to the low surface tension and the low broken plastic residue, the new active gelled acid will flowback easily after fracturing, so it has less damage to the reservoir. Compared with the conventional acid, the better performance, including the slower reaction rate, lower filtration, inducing cracks, self-redirection, enables the new acid system to realize the deeper reconstruction of reservoir, and then improve the effect of acid treatment. Abstract: In order to improve the effect of acid fracturing in reservoirs, a new active gelled acid system is developed.
