摘要:: 为进一步提高单井产量，更大程度地提高埕海22人工岛现有井口槽利用率，大港油田首次尝试“单筒双井+双分支水平井”技术。在一个井口槽钻出3～4个井眼，
增加储层钻遇率，提高泄油面积。首口试验井张海3939Z井两个分支均采用了大斜度井，通过使用硬轴自动找正、分支井眼回插固井和套管外封隔器辅助固井等技术，
顺利完成了大斜度分支井眼固井施工，实现了大港油田首口双分支井TAML 4级完井，解决了沙一、沙三段易漏失和沙三段高含气地层的固井难题，有效降低了施工风险。
单筒双井+双分支水平井技术联合可为类似井的施工提供宝贵的工程经验和相关数据。

Abstract:: To further increase the singlewell production and maximize the utilization rate of existing wellhead slots on the Chenghai 2-2

 artificial island, Dagang Oilfield attempted to apply the technology of "twinholeinmonobore + bilateral horizontal well" for the first time, that is, 3 or 4 wellbores were drilled in one

wellhead slot, in order to imrpove the drilling rate of reservoir, thereby increasing the drainage area. In the first test well, Zhanghai 3939Z, both laterals were highly deviated. Using

automatic hard shaft alignment, lateral backinsertion cementing, and external casing packerassisted cementing, the cementing of the highly deviated laterals was successfully completed.

Thus, the TAML Level4 completion of the first bilateral well in Dagang Oilfield was realized, with operation risks reduced effectively by avoiding the lost circulation in Sha 1 and Sha 3 and

other cementing problems in high gasbearing Sha 3. The technology of “twinholeinmonobore + bilateral horizontal well” can provide valuable engineering experience and relevant data for

the operation of similar wells.
