摘　　要：随着海洋油气资源的不断采出,导致地层能量逐渐亏空,部分井区开始进入了高产水阶段,无法实现油井自喷采油。因此,人工举升工艺逐渐获得完井工程师的青睐。然而,由于海上油田常年面临着地质条件复杂、平台空间狭窄、极端环境多样等诸多挑战,单一的人工举升无法适应于各类油井。基于工艺的复杂性与可行性,采用等级加权法明确了电潜泵采油为最佳的举升工艺,应用数值模拟对优选出的举升工艺进行参数优化设计,同时对压力、含水率、渗透率等参数进行敏感性分析。结果表明:泵功率随油藏压力、含水率和油藏渗透率的升高基本呈线性增长趋势,泵效在相同油藏压力下随油藏压力、含水率和油藏渗透率的升高,其衰竭速度加快。With the continuous production of offshore oil and gas resources,the formation energy is gradually depleted,and some well areas begin to enter the stage of high production water,and can not realize the oil production of wells.Therefore,artificial lift technology is gradually gaining favor among completion engineers.However,because offshore oilfields are faced with many challenges such as complex geological conditions,narrow platform space and diverse extreme environments,a single artificial lift cannot be adapted to all kinds of wells.Based on the complexity and feasibility of the process,the grade weighting method was used to determine the optimal lifting process for electric submersible pump production.Numerical simulation was used to optimize the parameters of the optimized lifting process,and sensitivity analysis was carried out on the parameters such as pressure,water content and permeability.The results show that the pump power increases linearly with the increase of reservoir pressure,water cut and reservoir permeability,and the pump efficiency increases rapidly with the increase of reservoir pressure,water cut and reservoir permeability.
