Abstract

Blowout preventer (BOP) is critical equipment during the exploration of O&G fields. It keeps the sealing between the well and the external environment and supports the blowouts from the well keeping the drilling safe. Current technology has been challenged to improve reliability, availability and safety specially when exploring new wells on deep and ultra-deep water. In the end, the development of new technologies applied for the BOP targets the overall cost reduction of the well lifecycle. The current weight and size of the BOPs are rulers for the size of the drilling platforms. The deeper the well, the higher the pressure and the bigger and heavier the equipment. This lead to the need of new platforms to operate in such range and increase of the exploration cost. Not to mention the problems with long hydraulic lines. New technologies should target reliability, weight and size reduction of BOPs. Current BOPs are a jigsaw of redundant equipment that might not make sense for future technology to be developed. However, only tested, proofed and reliable technology can be used in the final equipment. Nevertheless, radical changes in the current design of BOP will also trigger modifications on standards/regulations and procedures.
新一代防喷器发展面临的挑战
防喷器(BOP)是油气勘探中的关键设备。它保持了井与外部环境之间的密封,并支持井喷,确保钻井安全。目前的技术面临着提高可靠性、可用性和安全性的挑战,特别是在深水和超深水勘探新井时。最后,开发应用于防喷器的新技术的目标是降低油井生命周期的总体成本。目前防喷器的重量和尺寸是钻井平台尺寸的标尺。井越深,压力越高,设备越大、越重。这导致需要在这样的范围内运行新的平台,并增加了勘探成本。更不用说长液压管线的问题了。新技术的目标应该是降低防喷器的可靠性、重量和尺寸。目前的防喷器是一个冗余设备的拼图,对于未来的技术开发可能没有意义。然而,只有经过测试、验证和可靠的技术才能在最终设备中使用。然而,当前防喷器设计的根本变化也将引发标准/法规和程序的修改。
