海上薄油层多分支水平井钻井技术分析

Analysis of Drilling Technology for Multi-branch Horizontal Wells in Thin Oil Layers At Sea

石油对社会的发展有着不可替代的作用,但是对于海上的薄油层而言,其储量较为分散,因此要通过钻井技术来提高能源利用率。针对当前海上薄油层的开采,常采用多分支水平井钻井技术,但是在具体的作业中有技术难题。基于此,从海上薄油层多分支水平井钻井技术的难点入手,着重分析了海上薄油层多分支水平井钻井的技术控制要点。

Oil has an irreplaceable role in the development of society.However,for thin oil layers at sea,its reserves are relatively scattered.Therefore,drilling technology is needed to improve energy ef?ciency.For the current exploitation of thin oil layers at sea,multi-branch horizontal well drilling technology is often used,but there are technical problems in speci?c operations.Based on this,this paper starts from the dif?culties of multi-branch horizontal well drilling technology in offshore thin oil layers,and focuses on the technical control points of multi-branch horizontal well drilling in thin oil layers at sea.
