Mathematical Model and Numerical Simulation Considering Thermo-Hydraulic-Mechanics of Steam Stimulation
Based on seepage mechanics, solid mechanics and heat transfer theory, a mathematical model considering thermo-hydraulics-mechanics coupling of steam huff and puff was established, the multi-physics software was employed to solve the coupled model. Steam stimulation with single well was simulated, the simulation results, such as the seepage field, temperature and stress field of the process were gained. According to the analysis of the simulation results, some conclusions are drawn as follows: as the deformation of the rock is taken into account, in a cycle of steam soaking, the oil rate decline for a period of time, then it increase a little, later it decline, and the trend of decrease is slowed; the deformation of the rock plays an important role in the production of steam stimulation, it cant be neglected.
