威德福推出Victus智能控压钻井系统,这是一个工业4.0解决方案,应用智能控制、设备自动化等领先的技术。基于7600多次的MPD操作经验,Victus能够使钻井承包商无论在深水、潜水或是陆地上都能实现无与伦比的安全性和经济性。

通过将数十年的知识和全球数千口井的数据整合到一个先进的系统中,Victus开创了MPD的新时代。它集成了钻机设备,用于机器与机器之间的通信,实时分析井下条件,并从中心位置快速自动响应。它采用了一种经过时间检验的独家算法模型,精确地保持井底压力,以增强一次井控屏障。Victus还包括一个用于浮动钻井船的新型MPD立管自动化系统,将钻井平台的上升和下降时间降到以前无法达到的水平。一体化、紧凑、智能立管设计,安装时间从2天减少到不到20分钟。

Victus是一项突破,它将人类智能与机器通信结合起来,将MPD推向了新的高度。客户可以自信地继续钻井,就好像他们随时都有近乎无限的泥浆重量可供选择。他们可以减少钻井时间,消除大多数钻井危险,只有在必要时才使用防喷器。”

顺利钻进

该技术通过整合钻机设备,实现了机器间的互通、井况的实时分析、快速的自动响应,从而精确维持井底压力。无论你是在深水、浅水还是陆上部署Victus,任何时候你都可以顺利的钻进。
埃及近海某井,数小时内循环排出2次溢流;
沙特阿拉伯陆上某井,节省2万桶泥浆;
巴西深水某井,总井深钻至20000英尺;
美国深水某井,节省了1800多万美元。

战胜挑战

Victus智能MPD拥有一套可靠的系统,可以检测、控制、循环排出溢流。该系统使用的算法模型久经考验,已利用全球作业者数十年数千口井的数据进行了校准。因此,你可以避免钻进作业风险,并且仅在绝对必要时才会使用防喷器。

除了这些安全优势外,Victus还可以降低建井成本。更快的机械钻速(ROP)、更低的钻井液费用、更短的钻井作业时长、更优化的井身结构,可显著降低成本。

高精度作业

作为MPD作业的“大脑”,其智能控制系统可在动态井况下,提供快速、精确的压力控制。该系统利用先进的水力模型,可精准估测井底压力,并在数秒内确定出所需的井口回压。

先进的水力模型通过考虑流体与地层温度、流体压缩性、井眼岩屑的影响,精确确定出实时井底压力。智能控制算法可在不到一秒的时间内,向MPD设备发送自动命令,从而对井下条件做出快速响应。

PLC系统可轻松集成在钻机的任何位置,提供可靠的基础设施与网络安全。简化的用户界面可帮助您专注于关键参数,并可及时发送意外事件警报。基于状态监控与跟踪MPD设备性能,实现主动维护。自动生成可靠的报告,如每日总结或作业后分析,用以进一步优化钻性能。通过单一用户界面进行远程控制,可实现机器臂安装立管、完全关闭AID、锁定与解锁RCD、导流流体。从钻井设计到实时作业与作业后报告,确保了数据的一致性。

海上快速安装

用于海上与深水作业的自动化MPD立管是智能MPD系统的“心脏”。其集成、紧凑、智能的设计,可将安装时间缩短至20分钟内,从而将系统的安装与拆卸时间缩短80%以上,且决不会影响MPD作业。

连接中枢将海底控制脐带缆与放喷管线集成到一个易于连接的组件中。机械臂将连接中枢连接至无需手动操作的流速滑阀上,从而避免了月池中的手动作业。

智能旋转控制设备(RCD)技术可实现预测性维护与早期泄漏检测。

在安装连接中枢与MPD作业期间,水下监控系统能够提供可视化监控,从而减少对水下机器人的需求。
单个水下控制脐带缆可提供高性能光纤电缆,从而实现快速可靠的数据传输。

专为顶级性能而设计

除了最先进的MPD歧管外,该设备还拥有缓冲管汇、减压阀、打捞爪以及流体萃取系统。

MPD歧管可根据作业与客户需求进行完全定制。该歧管最多可控制四个节流阀,以增加冗余度,从而实现持续钻进。

当发生堵塞事故时,采用智能控制系统可远程进行节流阀的切换。

科里奥利流量计可以安装在节流阀的上游,以便在含气量较高的返出泥浆中,更准确的测量临界流速。

每个上游节流段都可以配备相应的流量计,以便持续作业。

利用智能控制系统可远程操控电动或液压阀。

优化设计,通过减少整个系统的压耗,使作业性能最大化。

打捞爪可以集成到MPD歧管,以减少占地面积,避免手动操作。

流体萃取系统可连续提取泥浆样品,用于气体成分分析与油藏描述,且不会中断作业。

DRILL WITHOUT DEFEAT
Victus ? intelligent MPD gives you the confidence to beat your drilling challenges.

For every well you drill, you have every reason to use managed pressure drilling (MPD). The proven gains make it difficult to justify drilling without it. Based on five decades of MPD leadership, Victus helps you to achieve all your drilling objectives with unmatched safety and cost savings.

It precisely maintains bottomhole pressure by integrating rig equipment for machine-to-machine communication, real-time analysis of downhole conditions, and rapid automated responses from a central location. At all times—whether you deploy Victus in deep water, in shallow water, or on land—you can drill without defeat.

OFFSHORE EGYPT CIRCULATED OUT 2 INFLUXES IN HOURS
ONSHORE SAUDI ARABIA SAVED 20,000 BARRELS OF MUD
DEEPWATER BRAZIL REACHED 20,000-FT TD
DEEPWATER US SAVED OVER $18 MILLION

VICTORY OVER YOUR CHALLENGES

Victus intelligent MPD includes a proven system that detects, controls, and circulates out influxes. The system uses a time-tested algorithmic model calibrated with decades of data in thousands of wells for worldwide operators. As a result, you can eliminate drilling hazards and use your blowout preventer only when absolutely necessary.

Alongside these safety benefits, Victus enables you to reduce well construction costs. Faster rates of penetration (ROP), reduced drilling fluid expenses, fewer rig days, and optimized well architecture add up to significant cost savings.

ACCURACY IN ACTION
INTELLIGENT CONTROL SYSTEM

As the brains behind the MPD operation, our intelligent control system provides fast, precise pressure control in dynamic well conditions. Using an advanced hydraulics model, the system precisely estimates bottomhole pressure and determines the required amount of backpressure to apply from the surface within seconds.
