Abstract:In the production process of heavy oil reservoirs dominated by horizontal well Stimulated Reservoir Volume (SRV) fracturing, as the oil field enters the middle and late stage of development, the sand production of oil Wells becomes increasingly serious, which will seriously affect the normal production of oil fields. Therefore, the sand and gravel transport rules during the steam stimulation of SRV fracturing in horizontal Wells have been studied in depth, which provides theoretical support for dealing with the problem of sand production in oil Wells. CFD simulation was used to study the influence of fracture pressure, inlet flow, inclination Angle and number of fractures on the formation of sand bed in horizontal Wells during steam stimulation of SRV fracturing. According to the simulation results, as the fracture pressure increases, the solid phase volume fraction first decreases and then increases, and the wellbore sand production is the minimum when the fracture pressure is 8MPa. The volume fraction of solid phase decreases with the increase of inlet flow. Under the same conditions, the smaller the well inclination Angle, the larger the solid phase volume fraction. The solid phase volume fraction decreases with the increase of the number of fracture lines.
