據世界石油2020年8月5日休斯敦報道，全球最大油田服務公司之一的美國哈里伯頓公司日前推出了Cerebro Force鉆頭傳感器，這是一種史無前例地從鉆頭上獲取重量、扭矩和彎曲測量數據的技術，這種技術可以提高對井下環境的了解，優化鉆頭設計以及提高鉆井效率。

Cerebro Force鉆頭傳感器建立在哈里伯頓公司成功的鉆頭振動傳感平臺的基礎上，利用井下數據減少或消除由鉆頭設計、井底鉆具組合和鉆井參數選擇引起的地面測量不確定性和低效率。通過在客戶界面設計(DatCI)過程，哈里伯頓公司的鉆頭專家區域網絡與運營商合作，為盆地特定應用定制鉆頭，并將使用來自Cerebro Force鉆頭傳感器的數據，為高效、精確的鉆井提供新的設計和優化參數。

哈里伯頓公司說：“實現鉆井性能要求有效地將能量轉化為巖屑。Cerebro Force鉆頭傳感器可以提供直接測量，幫助運營商優化鉆速，從而降低井建設成本。我們很高興能在我們的產品投資組合中增加唯一一款能夠精確測量應變和壓力的鉆頭傳感器。”

哈里伯頓公司說，這種技術適用于固定刀具鉆頭，并與傳統的電機和旋轉導向驅動系統兼容。

位于德克薩斯州西部的一家運營商最近使用了Cerebro Force鉆頭傳感器在鉆取井的曲線部分時提高了定向控制。Cerebro Force鉆頭傳感器的數據發現了幾個限制性能的問題，而哈里伯頓公司為此專門開發了一個緩解方案，該方案將優化鉆井實踐和底部鉆具組合設計并減少38%的鉆取曲線部分所需的時間。

Halliburton introduces Cerebro Force drill bit sensors

Halliburton introduced Cerebro Force in-bit sensors, a first-of-its-kind technology that captures weight, torque and bending measurements directly from the bit to improve understanding of downhole environments, optimize bit design and increase drilling efficiency.

Built on Halliburton’s successful in-bit vibration sensing platform, Cerebro Force utilizes downhole data to reduce or eliminate surface measurement uncertainty and inefficiencies caused by bit design, bottomhole assembly and drilling parameter selection. Through the Design at the Customer Interface (DatCI) process, Halliburton’s local network of drill bit experts, collaborate with operators to customize bits for basin-specific applications, and will use data from Cerebro Force to inform new designs and optimize parameters for efficient and precise drilling.

“Achieving drilling performance requires efficiently converting energy into rock cutting. Cerebro Force in-bit sensors provide direct measurements to help operators optimize their rate of penetration to reduce well construction costs,” said David Loveless, vice president of Drill Bits and Services. “We are excited to add the only in-bit sensor that accurately measures strain and pressure to our portfolio of products.”

The technology is available on fixed cutter drill bits and is compatible with conventional motor and rotary steerable drive systems.

An operator in West Texas recently deployed Cerebro Force to improve directional control while drilling the curve portion of its wells. Cerebro Force data identified several issues that limited performance, and Halliburton developed a mitigation plan that optimized drilling practices and BHA design. This reduced the time to drill the curve section by 38 percent.
