A method of calculating productivity for gravel packed well;
砾石充填防砂井产能预测方法
There exist many factors influencing the productivity in gravel packed and sand controlled wells, its correlation is complex, a precision and practical model for prediction is hard to be established by using conventional theory.
影响砾石充填防砂井产能的因素很多,关系非常复杂,常规理论方法难以建立准确、适用的预测模型。
Based on what had been done previously in the aspect of pressure losses across perforation and gravel pack, the paper presents a new formula to calculate the pressure losses across perforation and gravel pack,and calculates the skin factor through the introduced popular equation of radial flow.
在以往对砾石充填井压降分析的基础上,给出了一种以普通径向流方程为基础计算井筒附近收敛流动和射孔-砾石充填段的压降,再根据完善井与非完善井压降之间的关系,求出表皮系数的方法。
