水平侧支井暴露出大量的产油储集岩 ,有利于一定的油藏应用。但是 ,在水驱非均质碳酸盐油藏中 ,它却可能是一个主要的风险成分。长侧支段增加了将不希望有的地质条件暴露出来的可能性。高产水率可以导致低产油率和过高升举成本。一种将可多次坐封的膨胀跨式双封隔器和一台喷射泵结合起来的新型工具 ,可以控制垂直井和水平井中水的产出 Horizontal side branch wells exposed a large number of oil-producing reservoir rocks, is conducive to a certain reservoir applications. However, it can be a major risk component in water-flooded heterogeneous carbonate reservoirs. The long leg segments increase the possibility of exposing unwanted geological conditions. High yields can result in low oil rates and excessive lifting costs. A new type of tool that combines a multi-stage, enclosed strapping double packer with a jet pump to control water production in both vertical and horizontal wells
