在各种条件油藏中,水平和多分支完井是优先考虑的技术。然而,尽管它们与油藏的接触面最大,却易于向井跟部锥进。这是沿井摩擦压降和渗透率变化的结果。可引起严重腐蚀和筛管堵塞的环空流量是另一项挑战。20世纪90年代早期流入控制器(ICD)作为一种有效的工具可以解决上述问题。ICD目前应用广泛,可应用于各类井况。油田监测证明,ICD具有控制井流动剖面的能力。 Horizontal and multi-branch well complementation is a priority in various types of reservoirs. However, although they have the largest contact with the reservoir, they tend to cone into the well and heel. This is the result of changes in frictional pressure drop and permeability along the well. Annular flow, which can cause severe corrosion and blockage of the screen, is another challenge. In the early 1990s, inflow controllers (ICDs) were an effective tool to solve the above problems. The ICD is currently widely used and can be applied to various well conditions. Oilfield monitoring has demonstrated that ICDs have the ability to control well flow profiles.
