新型双插式井下电缆穿越器结构及其在渤海油田的应用

The Structure of A New Type of Double Plug-in Downhole Cable Penetrator and Its Application in Bohai Oilfield

渤海油田多数生产井采用下入电潜泵的方式进行生产,其井下机组电缆需要穿越过电缆封隔器及油管挂到达地面供电系统。现有井下电缆穿越器或密封性差,或现场连接操作复杂,费时费力。本文介绍了一种新型双插式井下电缆穿越器。该电缆穿越器可以有效提高单项作业时效60%,节省生产时间,降低工期成本,有助于实现渤海油气田的提质增效,具有广阔的应用前景。

Most production wells in Bohai Oilfield use electric submersible pumps for production.The cables of the downhole units need to pass through the cable packer and tubing hangers to reach the surface power supply system.The existing downhole cable penetrators have poor sealing performance,or complicated on-site connection operations,which are time-consuming and labor-intensive.this article introduces a new type of dual plug-in underground cable penetrator.Field operations have shown that the cable penetrator can effectively improve the time efficiency of a single operation by 60%,save production time and reduce construction period The cost will help to improve the quality and efficiency of the Bohai oil and gas fields,and has broad application prospects.
