海上油田水平井控水技术研究与应用——以Wen19-1N-C1H井为例

Research and Application of Horizontal Well Water Control Technology in Offshore Oil Field——Well Wen19-1N-C1H

南海西部油田大部分油井含水已超过60%,以Wen19-1N-C1H井为例,在油藏驱动类型、含水上升规律、出水层段预测及控水效果评价等油藏研究的基础上,通过对目前不同控水方式的对比分析,充分利用了该井的裸眼管外封隔器,采用简易、经济的中心管控水工艺,取得了良好的增油降水效果。Wen19-1N-C1H井控水的成功,对新井在完井阶段管柱设计及后期高含水油井控水,提供了良好的借鉴意义。

The water content in most oil wells in the west of the south China sea is more than 60%. Taking the well of Wenl9-1N-C1H as an example, the paper studies the reservoir drive type, the law of water cut rise, out of the water layer prediction, and the evaluation of the effect of water con- trol, etc. By contrastive analysis of the different ways of water control, the paper makes full use of the open hole packer, uses simple and easy mechanical water control technology, has obtained the good effect of oil increase precipitation. The success of well Wenl9-1 N-C1H water control provides a good reference for new wells in the late stage of completion string design and high water cut oil well water control.
