一种井下线缆穿越接头
By designing a downhole cable crossing connector, the cable in the inner tube is switched to the outer tube, and the pressure difference is balanced by injecting motor oil into the capsule tube. This solves the sealing and insulation problems of downhole tools under high pressure differential environment, and enables the normal operation of downhole tools and the protection of cables.

Abstract
本发明涉及井下油气管缆接头技术领域，具体是一种井下线缆穿越接头，包括转接头、转接插座和第一连接管，转接插座内部具有第二线缆通道和第二液流通道，第二线缆通道的出口连接有第二线缆密封接头组件；转接头具有第一液流通道、第一线缆通道A、第一线缆通道B和第三线缆通道；第三线缆通道内的第三线缆接线后注入电机油，第一线缆密封接头组件A、第一线缆密封接头组件B和第二线缆密封接头组件使第三线缆通道保持密封。本发明可将转移到第三线缆通道的环形空间内的动力缆、信号缆穿越出设备，实现和井下工具的连接；通过胶囊管内电机油传导压力，使得内外压差减小，保证了井下工具线缆连接部位的正常工作，同时也保证了胶囊管内线缆的绝缘性。
