鱼骨状分支水平井地质设计技术

分支水平井是目前比较先进的油气藏开发手段,文章从分支水平井部署的砂体优选、精确的砂体储层预测、分支水平井的平面位置设计和轨迹优化等几个方面描述了水平分支井的地质设计技术,并提出在分支水平井钻进过程中进行实时跟踪分析,以确保分支水平井的顺利实施,从而达到高效开发油气藏的目的。

Geological design technology of fish bone-branch horizontal well

multilateral horizontal drilling is a much advanced development technology now,this paper describe this technology in following respect： optimizing the sand for deploying the multilateral horizontal well、accurate reservoir prediction、design of horizontal position and optimizing the tracking of the multilateral horizontal well.Real time tracing technology was used in the drilling of multilateral horizontal drilling to ensure the successful implement of drilling which can develop the oil and gas reservoir with high efficiency.
