针对常规电桥投送器外径较大、无法在套管变形井中实施下电桥工艺的问题，研制了多功能电桥投送器。该工具的外径、长度比常规电桥投送器分别小6mm和452mm，通过能力强，能保证电桥顺利下井；同时集投送电桥与打水泥塞功能于一体，在下完电桥后用原管柱打水泥塞，减少了作业工序。32口井的现场试验表明，该工具既能满足内通径大于108mm套管变形井下电桥的需要，又能解决常规电桥投送器无法打水泥塞的问题，施工成功率为100%。

The conventional electric bridge drop-in tool cannot carry out lowering electric bridge in casing deformation wells since its outside diameter is relatively large, a multifunction electric bridge drop-in tool is developed. The OD and length of the new tool are respectively 6mm and 452mm less than that of the conventional bridge drop-in tool, ensuring smooth lowering of the bridge. The multifunctional tool can also accomplish cementing plug with the original pipe string after dropping the bridge. Tests on 32 wells shows that the multifunctional electric bridge drop-in tool can meet the need of lowering bridge and cementing plug in casing deformation wells with an ID of over 108mm.
