ExxonMobil Upstream Research has made two moves to further develop its Internal Shunt Alternate Path(ISAPT) well completion technology.
埃克森美孚上游研究公司已经进行了两次攻关活动，进一步发展自己的Internal Shunt Alternate Path(ISAPT)内部替补流动路径完井技术。
Advances in controllable open-hole completions continue to be a focus area for ExxonMobil, as many deep-water-developments utilize open-hole completions to maximize reservoir deliverability.
可控裸眼井完井技术的进步继续成为埃克森美孚公司关注的重点领域，这是因为在许多的深水开发井中只有利用裸眼井完井技术才能够使得储层产能最大化。
ExxonMobil continues to pioneer completion technologies that increase control and reliability in the open-hole environment, without increasing operational complexity. ISAPT sand control screens and ISAPT packers provide the additional flexibility required to develop challenging reservoirs.
埃克森美孚公司继续倡导先进的完井技术，增加在裸眼井环境中的控制和可靠性，而不增加作业的复杂性。ISAPT内部替补流动路径完井技术防砂筛管和ISAPT封隔器也使得开发具有挑战性油藏进行完井作业变得更加灵活。
ExxonMobil has awarded Schlumberger a license for the ISAPT sand screen and has awarded Weatherford a license for the ISAPT packer for open-hole completions.
埃克森美孚已授予了斯伦贝谢公司在裸眼井完井中使用ISAPT防砂筛管的许可证和授予威德福公司使用ISAPT内部替补流动路径完井技术封隔器的许可证。
ExxonMobil said the ISAPT screens increase well reliability in sand-prone reservoirs. The system provides internal alternate flow paths called “shunt tubes” in the down-hole tool to effectively gravel pack producing horizons. The shunt tubes enable gravel packing even if sand prematurely blocks the well annulus.
埃克森美孚公司表示ISAPT筛管能够增加在易出砂储层进行完井作业的可靠性。该系统提供了被称为“分流管”的内部交替流动路径的井下工具，能够在生产层段范围内进行有效的砾石充填。分流管能够保证砾石充填作业，即使是在砂子过早堵塞了油井环空的情况下。
The open-hole packer for the ISAPT system can extend gravel packing capabilities to more than 5,000 ft (1,524 m) while reducing installation time, ExxonMobil said. The packers are designed for use with ISAPT screen to isolate multiple water-bearing zones in a production well during gravel packing of sand-prone reservoirs.
埃克森美孚表示ISAPT内部替补流动路径完井技术系统的裸眼封隔器可以提高砾石充填能力至超过5000英尺(1524米)，同时减少安装时间。该封隔器是设计与ISAPT内部替补流动路径完井技术筛管共同使用，隔离多个含水生产层易出砂储层生产井的砾石充填过程中。
