摘要:石油(工业血液)是世界消费量最大的基础经济资源并且处于产业链顶端,石油价格的波动,将导致相关基础资源整体价格的飙升(蝴蝶效应),形成商品价格的上涨,导致通货膨胀,引发经济和金融危机,甚至引发能源战争。油气资源已经成为影响我国现代化建设全局和国家安全的重要战略资源。石油是不可再生资源,随着近来的不断开采,其储量越来越少,因此,需大力发展新的开采方式,提高原油的开采率。
水平井技术是20世纪80年代石油界迅速发展并日益完善的一项综合配套技术,其根本目标是提高油气产量和提高油气采收率。水平井是指在底下某一深度的地层中沿水平方向钻出一段水平井眼的工艺过程。水平井钻井技术是指在定向钻井技术的基础上发展起来的。自20世纪80年代到90年代初,水平井技术在世界范围内得到迅速发展和完善,并被称之为石油工业的第二次革命。

Abstract: The Design Of ICD About Heterogeneous Reservoirs Horizontal Wells. This paper describes the equipment, function, and benefits of the innovative multilateral well completion installed in the Wytch Farm M-15 well operated by BP Amoco. This completion enables production from two different sections of an oil reservoir. Effectively, it is a multilateral well equipped with advanced completion functions much like two wells but without doubling the construction expense. This advanced completion included three hydraulic wire line-retrievable flow control devices and an electric submersible pump (ESP). In addition, down hole electronic instruments provide monitoring of pressure, temperature, and flow. With the inflow-control valves successfully operating in this well, we further optimized production, including commingled production from both laterals. This completion set several firsts: one for the long length of its extended reach and another for the first surface controlled flow device installed below an electric submersible pump (ESP). The team estimated that flow control would allow recovery of an additional 1 million bbl [158 900 m3] of oil that otherwise would not have been economically recoverable.
