Study On Thermal Recovery Technology In Jiang JQ Thickened Oil Pool

The steam soak and steam flooding is the effective model for the development of the igneouss fractured thickened oil pool at home and abroad.They all make the high temperature steam pour into the layer in the underground.The steam soak is the technology which pour a finite amount steam into the oil well.Then close the well for a time.After the thermal energy of the steam spread into the layer.The oil well will be opened.Steam flooding is one of the major methods for producing heavy oil.It pour the steam into one oil well or many wells.And it can heat the more viscosity thickened oil for viscosity reducer.Then in the fact of the steam distillation.Displacing the oil into the near well to produce oil.The porosity and permeability of JQ thickened oil pool is higher.To study the steam soak and steam flooding technology in JQ thickened oil pool is very important.The steam soak technology application to JQ thickened oil pool.We can come to a dicision that the steam soak technology can increase the well production rate.And the heat connected level is improved.But the heat loss can reduce steam quality,and the well interference,the oil layer take in the steam is not equal,which are all problem.We need to resolve by raise the steam injection rate and reduce the steam injection time,and they also need the combined steam soak stratification and layer selectionsteam injection technology.which are made to improve the effect of the steam soak.The steam flooding technology application to JQ thickened oil pool.We can come to adicision that it takes a important effect on improving the oil production.But the oil well containing water rise too fast,and the steam channeling is a big problem.We need select the better high temperature broke down fluid and judge the layer if exist the big holes or not,and confirm the dosage of the broke down fluid.All these can effectively relieve the contradictions of plane,interlayer and inherent layers,and improve the effects of oil field exploitation by steam drive process.
