为了解决 CB 油田油井非能量供给造成液量下降的问题，以油井实际生产动、静态资料为基础，利用油层物理实验方法，从储层水敏、速敏、应力敏感以及蜡晶沉降堵塞等角度，建立了储层伤害定量预测模型；同时引入伤害指数，建立了基于油井生产动态的储层伤害综合评价方法，将该方法与储层伤害机理相结合，可以有效确定油井储层伤害的类型及伤害程度。该方法在 CB 油田得到成功应用，说明该方法对于确定储层伤害类型、伤害程度以及油井合理生产参数具有重要意义。

To solve the problem of liquid production decline caused by non - energy supply in CB Oilfield,based on the dynamic and static data of oil wells,a quantitative formation damage prediction model was built by considering water sensitivity,speed sensitivity,stress sensitivity and wax deposition blockage. By introducing the damage factor,an integrated evaluating method of formation damage was proposed. Combined with the formation damage mechanisms,this method can be used to determinate effectively the type and degree of formation damage of oil wells. The method was successfully applied in CB Oilfield. This indicated that the method can quantitatively determinate the type and degree of formation damage and reasonable production parameters of oil wells to ensure normal production.
