“…In addition to using profile control method to control the injection amount of displacement agent in high‐permeability oil layer, relevant research shows that the injection amount can be controlled by using flow control device in the process of oil field production, because the pressure of solution (Bernoulli's law) changes when the fluid flows through the flow control device, thus controlling the injection amount of fluid . In the oil industry, tools of adjusting fluid pressure to control fluid flow effect are mostly applied to drilling technology, oil and gas exploitation, offshore work, and oil and gas transportation . For downhole operation and production, some scholars have studied a flow control device which can realize the completion of horizontal wells, prevent early water and gas breakthrough, and improve the oil recovery.…”

In order to solve the problem of reservoir heterogeneity in the process of oil displacement, Daqing oilfield has proposed a partial pressure injection technology (using partial pressure tools). The partial pressure tool can improve the overall oil displacement effect by reducing the pressure of the displacement agent and adjusting the injection amount of the displacement agent in the high‐permeability oil layer. In order to study the effect of the partial pressure tool on the polymer solution, the flow characteristics of the polymer solution in the partial pressure tool were studied by finite element analysis, and the results of the numerical simulation were compared and verified by laboratory experiments. Then, the optimal structural parameters of the partial pressure tool were selected by orthogonal experiments. Finally, field tests were carried out to verify the effectiveness of the partial pressure tool. The results show that when the flow rate is 10 m3/d, the pressure drop of the polymer solution reaches 6.08 × 105 Pa and the viscosity loss rate reaches 6.69%, while the physical parameters of the solution change periodically under the action of the partial pressure tool. At a low flow rate, the results of the laboratory experiment and numerical simulation fit well, and the optimal structural parameters of the partial pressure tool are selected. Field tests show that the oil recovery is increased by 2.54% after using partial pressure tools. The research results are of great significance to the study of resolving interlayer conflicts and enhancing oil recovery.
