The flow rate, perforation radius and shotdensity are the key parameters influencing the pressure drop across gravel pack.
分析结果还表明,油井产量以及射孔孔径和孔密度是影响砾石层压降的重要因素。
2
Discusses the importance and design scheme of perforating charges with large diameter and perforating guns with high shotdensity;
描述了大孔径射孔弹和高孔密射孔枪系统的设计;
3
The shot diameter, shotdensity and shot phasing related to the collapsing strength coefficient are analyzed, and the result is helpful to the perforation optimum design.
