NOV（國民油井華高）的Tolteq TruVertical是一種簡單可靠的垂直監控系統，可以獲得重要的測量信息，包括井斜角、方位角以及工具面方向。在作業中如果與NOV的Tool Tracker系統集成，可獲取工具歷史日志以及環境數據。固件更新可確保工具在全壽命周期內持續改進。TruVertical工具還具有可擴展性，用戶可添加伽馬以獲得更多井下信息。該工具堅固的設計，使其可承受井下嚴重的沖擊與振動。
相比于傳統工具，Tolteq TruVertical的特點與優勢鮮明，包括：1提供重要的信息，如井斜角、方位角、工具面、井深、電池電壓、地層傾角、重力、磁場、溫度、沖擊以及振動；2與Tool Tracker系統集成，可獲取記錄的工具歷史以及環境數據；3可添加伽馬射線測量工具，以獲得更多井下信息；4可承受井下嚴重的沖擊與振動；5能夠適應未來的固件更新，可確保工具處于最新狀態。
最近，NOV公司與印度一家油氣公司合作，成功應用了其Tolteq系列新的作業工具–TruVertical?？蛻粢蟊O測并定向鉆進一口垂直井，控制井斜在4度以內，該井先前由于地質因素干擾，井眼偏離了設計軌跡。之前嘗試了多種常規方法，例如安裝扶正器、控制轉速、控制鉆壓，都不起作用。
該開發商選擇了NOV的TruVertical無人系統作為解決方案，只需定向井工程師，縮小了井隊作業人員規模。結合TruVertical工具與7/8 5.0 Vector鉆進馬達，能夠將井眼從1071米處的5.85度導向至完鉆井深（1194米）的3.74度，同時保持垂直井眼至目標層位。
轉向工具產品經理Ozzy Silva指出：“我們很高興看到Tolteq系列產品的持續成功。TruVertical工具與垂直監測標準工具截然不同，因為它被設計為無人系統。這意味著我們可以減少現場人員數量，提高安全性并降低成本?！?/span>
TruVertical工具是一套簡單、可靠的垂直方向監測系統，可提供重要的定向信息，包括井斜角、方位角與工具面方向。在鉆直井或簡單定向井時，該系統的智能用戶界面設計、簡易的裝配以及簡捷的操作流程，可最大限度幫助作業者擺脫對服務商的依賴。

We recently achieved success with a major operator in India with our Tolteq? TruVertical? tool. The client needed to monitor and directionally steer a vertical well to less than 4° where previous wells had deviated due to geological disturbances. Conventional methods such as stabilizer placement, controlled RPM, and WOB parameters had previously proven unsuccessful. The client selected our TruVertical unmanned system as a solution, reducing the crew size to only the required directional driller. The TruVertical tool was paired with our 7/8 5.0 Vector? drilling motor, allowing the client to steer the well back towards vertical from 5.85° at 1071 m to 3.74° at total depth (1194 m) while maintaining a vertical well profile and successfully reaching the target zone.
?“We’re excited to see the continued success of our Tolteq product line,” noted Ozzy Silva, product line manager for drift tools. “The TruVertical tool is notably different from typical vertical monitoring tools because it’s designed to operate as an unmanned system. That means we can reduce the amount of people at the rigsite, improving safety and reducing costs.”
?The TruVertical? tool is a simple and reliable vertical monitoring system that provides access to valuable directional information, including incli-nation, azimuth, and toolface. The intelligent user interface design, simple rig up, and easy operating procedure helps the operator minimize the dependency on the service provider for vertical or simple directional wells. Visit our TruVertical tool product page to learn more about how you can reduce your operating costs when drilling vertical or low-angle well sections.
?Description
The Tolteq? TruVertical? tool is a simple and reliable vertical monitoring system that provides access to valuable survey information, including incli-nation, azimuth, and toolface. Integration with the Tool Tracker? system allows access to logged tool history and environmental data. Firmware updates ensure continuous improvement throughout the life cycle of the tool. The TruVertical ?tool is expand-able, allowing the user to add gamma for additional visibility, and the rugged design withstands the shock and vibration of harsh downhole environments.
?Features/Benefits
- Provides access to valuable information, including: inclination, azimuth, toolface, depth, battery voltage, dip angle, gravity, magnetic field, temperature, shock, and vibration
- Integrates with Tool Tracker to access logged tool history and environmental data
- The ability to add gamma enables additional visibility
- Handles the shock and vibration of harsh downhole environments
- Future firmware updates ensure the tool is kept up-to-date
