摘要
双电泵完井方式是应对高产油井分层开采井筒举升的有效方法。针对插入式丢手封隔器和过电缆封隔器,分别论述了单油管、双油管及同心油管等不同双电泵分层完井管柱结构的优缺点,明确了双电泵分层完井施工要点。过电缆封隔器同心管双电泵分层完井工艺将为海上高产深井的开发提供有力的技术支持。
The well completion technology of dual-ESP is an effective method to cope with the wellbore lifting in high production wells. For plug-releasing packer and through-cable packer, the paper respectively discusses the advantages and disadvantages of the single pipe, double pipe and concentric tubing completion pipe string structure. It clarified the key points in dual-ESP completion construction. The stratified completion technology of dual-ESP with the concentric tube of through-cable packer will provide a powerful technical support for the development of the high yield deep well at sea.
