Summary In this paper, an improved characterization of three-phase flow under high-pressure-air-injection (HPAI) conditions was achieved on the basis of experimental results and numerical reservoir simulation. A three-phase coreflood experiment was conducted at reservoir conditions, using 37°API stock-tank oil, an 84% nitrogen and 16% carbon dioxide flue-gas mixture, and 3% potassium chloride brine. The aim of the test was to evaluate the effects that the highly liquid-saturated front produced by the thermal reactions has on the mobility of each phase. Departing from connate-water saturation and reservoir pressure and temperature, sequential injection of water, gas, and oil was carried out, followed by a final gasflood to residual liquid saturation. Other two- and three-phase tests performed on this rock specimen were published elsewhere (Niz-Velásquez et al. 2009). Numerical history matching was employed to determine oil/water and liquid/gas relative permeability (kr) curves for both imbibition and drainage cases. A combustion-tube (CT) test was simulated using conventional kr curves and a set that included hysteresis. The degree of hysteresis observed during the coreflood test was maintained for the CT simulation. History matching of the coreflood showed that kr to the gas phase is much smaller during liquid reimbibition than during drainage. The use of gas-phase hysteresis for the CT test allows for a better matching of liquid volumes and pressure drop. Analysis of the simulated data suggests that the reduction in gas-phase mobility encourages an early increase in the oil rate, which is more consistent with experimental data than what is predicted by a model with conventional kr. The analysis also reveals that water distilled below the saturated steam temperature plays an important role in the increase of liquid saturation and oil mobilization. The improved characterization of relative permeability considering gas-phase hysteresis for simulating HPAI enhances the predictive capability of available commercial simulators, providing a more certain method to evaluate the technical and economical feasibility of a project. The ability to predict an early increase in oil rate, consistent with experimental observations, results in improved economics for the project.

Abstract Subsea minerals exist in the deep water within Japanese exclusive economic zone. However, the development of subsea minerals is not commercialized. The Air-lift pump is the promising method for subsea minerals transport. It is significant to estimate the amount of lifting ore when the conditions of submergence ratio and supplying air volume are changed. The estimation of the amount of lifting ore needs the void fraction in three phase flow and friction loss in pipe. Therefore, the empirical methods to estimate the void fraction and friction loss in mainly vertical pipe were proposed in the previous studies. However, the lifting system for subsea minerals has not only vertical pipe but inclined pipe. There are few works for flow assurance on three phase flow in inclined pipe. Then we conducted the scale model experiment to investigate void fraction and friction loss. The experiment was conducted in the conditions of the five kinds of inclination angles. We used the glass beads as solid particles in the experiment. The glass beads were 4mm in diameter and 2553kg/m3 in density. The internal diameter of pipe was 26mm. We applied the empirical method for vertical or horizontal pipe proposed in previous researches to the present experimental condition. Then we compared the experimental results with the calculated ones on void fraction and friction loss. As the results, the calculated results were in good agreement with the experimental ones. Therefore, it was suggested that the void fraction and friction loss in the inclined pipe could be calculated by the empirical method based on the experiment on the vertical or horizontal pipe.

Flow velocity measurement was an important research of oil-gas-water three-phase flow parameter measurements. In order to satisfy the increasing demands for flow detection technology, the paper presented a gas-liquid phase flow velocity measurement method which was based on energy demodulation algorithm combing with time delay estimation technology. First, a gas-liquid phase separation method of oil-gas-water three-phase flow based on energy demodulation algorithm and blind signal separation technology was proposed. The separation of oil-gas-water three-phase signals which were sampled by conductance sensor performed well, so the gas-phase signal and the liquid-phase signal were obtained. Second, we used the time delay estimation technology to get the delay time of gas-phase signals and liquid-phase signals, respectively, and the gas-phase velocity and the liquid-phase velocity were derived. At last, the experiment was performed at oil-gas-water three-phase flow loop, and the results indicated that the measurement errors met the need of velocity measurement. So it provided a feasible method for gas-liquid phase velocity measurement of the oil-gas-water three-phase flow.
