水平井施工中电缆在进出井口补心经常会由于摩擦和拉力过大以至于使电缆拔线,切割造成电缆损伤或是绝缘不好,造成施工难度增大或是测井失败。为了解决井口电缆损伤的现状,我们通过实验和论证,制作了方补心水平井井口防磨器和圆补心水平井井口防磨器,适应井队现有的两种不同井口,施工中保护了电缆,增加电缆使用寿命、提高测井一次成功率。
Horizontal well construction of the cable in and out of the wellhead often due to friction and pulling force is too large to pull the cable, cutting cable damage or insulation is not good, resulting in increased construction difficulty or logging failure. In order to solve the current situation of the damage of the well head cable, we made a series of horizontal well wellhead anti-wear device and circular fill heart horizontal wellhead anti-wear device by experiment and demonstration to adapt to the existing two different wellheads in the well team, Cable, increase cable life, improve logging success rate.
