A method of calculating productivity for gravel packed well; 砾石充填防砂井产能预测方法 2. 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。 3. 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。 补充资料：砾石填充液 分子式：CAS号：性质：砾石填充作业中，用来携带砾石或砂粒并将其运送到井下预定位置的液体。这种液体要求具有一定的黏度，不含有可能伤害地层及砾石层渗透率的物质，能较快降解，使砾石柱在井下能保持最佳的填充密度和过滤能力。 说明：补充资料仅用于学习参考，请勿用于其它任何用途。 参考词条 ©2011 dictall.com
