射孔段 meaning in English
perforated interval
perforation interval
Examples
- The forward calculation shown that when providing current through whole casing pipe , the electrical potential on surface is mainly effected by shallow resistivity anomaly , whereas when providing current only at gun perforation position , the electrical potential is on surface mainly effected by corresponding resistivity of gun perforation position
正演结果表明：在全井套管供电时，地表观测电位主要受浅层电阻率不均匀性的影响；在射孔段供电时，地表观测电位主要反映射孔段的电阻率分布。
