The automatic inflow control device (AICD) used for water control and gas recovery in gas wells as the core component of gas well intelligent layered/segmented production and water control technology is very important for the development of advanced well completion (AWC) technology in water-producing gas reservoirs. Therefore, the design of AICD to ensure that the gas flows smoothly inside it and to keep water under control to a greater extent can maximize the performance of the AICD, and the most important thing is to restrict the water in the formation from entering the wellbore. However, currently, there are very few designs and research on the AICD used for water control and gas production in the gas wells, and the performance of this type of tool and the law of gas and water flow inside it are not perfect, so more in-depth research is needed. In this paper, a new type of AICD is designed to realize the function of water control and gas flow smoothly, and the DoE of the new AICD is carried out, determining the factors that will affect the key technical indicators and the factors that may have interactive effects, using the numerical simulation method of computational fluid dynamics to carry out optimal design, conducting fluid physical property sensitivity analysis, and flow rate applicability analysis. The results show that the tool is not sensitive to the viscosity of water and gas in different gas reservoirs but is very sensitive to the density of water and gas. When the gas/water flow rate ratio is less than 4, it can exert its water control effect. In addition, the results of multiple sets of physical experiments are well consistent with the simulation results; the average deviation of single-phase water is 10.91% and the average deviation of single-phase gas is 11.85%. Computational fluid dynamics and physical experiment results show that, under these conditions, the difference in fluid flow characteristics can be fully exploited; the channel is automatically identified to produce a small gas pressure drop and a large water flow pressure drop. The research in this paper belongs to the key technology of the AWC technology of gas wells in the new water control strategy of the current and has a certain reference value to make up for the defects of drainage gas recovery technology in the water management strategy..

“…The floating ball AICD identifies fluids using the density difference of fluids, and it induces fluids into different channels; thus, water or gas control is realized . The channel AICD has special flow paths that are suitable for different fluids and can induce different fluids into different flow paths; thus, the additional pressure loss of an unexpected fluid is increased. − However, AICDs, which generate different pressure losses using density differences, cannot control water accurately because the effect of flowing fluids on movable components is not fully considered. AICDs, which generate different pressure drops based on viscosity difference, cannot control water efficiently because they do not have movable components.…”

Horizontal wells are prone to water coning and imbalanced inflow profile problems because of reservoir heterogeneity, the “heel-toe” effect, and different water avoidance heights. To solve these problems, an automatic inflow control device (AICD) technology is developed, as the traditional inflow control device (ICD) technology is frequently invalid after water breakthrough. In this study, a novel water control tool, an automatic inflow-regulating valve (AIRV), was designed to balance inflow profiles before water breakthrough and to limit water inflow after water breakthrough. With the use of a movable part, the AIRV can quickly distinguish fluids and limit the water output based on differences in fluid properties and the swirling flow principle. The water control efficiency and ability of the AIRV were simulated and optimized using computational fluid dynamics (CFD) software and verified experimentally using a water control testing system specially designed for the AIRV. We observed that (1) the total water force on the movable component of the AIRV is notably larger than that of oil because the swirling intensity of water is significantly higher than that of oil; moreover, the force directions of water and oil are opposite to each other. (2) The AIRV is sensitive to the flow rate and fluid viscosity but not to fluid density. (3) A higher water cut results in a higher AIRV pressure loss. The results of the CFD simulation and experimental test demonstrated that the AIRV has a significant water control ability and efficiency, particularly under conditions of a high production rate and high water cut. Thus, the AIRV can be used to enhance the control of water inflow before and after water breakthroughs in horizontal wells.

“…Coronado et al put forward a new concept of hybrid design development, which uses the best characteristics of restriction and friction design to improve the erosion resistance and the ability to effectively balance inflow of ICDs. Least et al proposed an independent inflow control device (AICDs) and conducted laboratory experiments. The results show that the AICD can utilize 61% more oil and gas resources than ICDs in completion design, bringing significant benefits to production enterprises and enterprises participating in completion design and modeling of new wells.…”

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.
