大數據的變革已經悄然滲入人們的生活，石油行業一些先進的公司也嘗試著使用大數據分析，結合移動互聯網和物聯網技術，大力發展“智能油田”，更精準的判斷井位，降低鉆井事故率，降低勘探、集輸、煉化和銷售各板塊的成本，非常規油氣的勘探也越來越精準，另外，對公司日?；顒舆M行大數據技術的深入挖掘，公司可以高效預測未來真實的情況?？傊?，大數據已經成為油氣行業未來的發展趨勢。
貝克休斯SureFIELD?全球遠程數采裝置及通信工具用于采集并傳輸井場傳感器及地面控制器的實時數據，能夠實現從任意連接地點對井的連續遠程監測。此裝置是貝克生產決策服務（PDS）產品組合的一部分，設計用于未安裝監測系統的井或者用于已安裝SCADA系統的井，旨在增強井下儀器儀表的數據回收。SureFIELD全球遠程數采裝置配有衛星通信解調器的控制器，能夠通過衛星按照預設時間間隔上傳數據，或者按需進行不間斷傳輸。
系統安裝就位后，操作人員便能夠瀏覽實時生產數據，其中包括電潛泵工作參數、分布式溫度傳感系統參數、永久式壓力/溫度計及流量計參數等。此裝置同時能夠對油氣井生產裝置進行安全、雙向的控制，從而實現增產目的。
SureFIELD全球裝置來自于貝克休斯極具可靠性的SureFIELD產品組合，該組合的關鍵組成還包括SureFIELD DataHub SCADA系統以及Vision 網絡應用程序，主要用于數據瀏覽、趨勢跟蹤及報警。通過SureFIELD DataHub裝置收集的數據經過處理、緩沖和壓縮后，由SureFIELD全球通信裝置發送，最終呈現在臺式機或筆記本上的Vision用戶界面上。相較于先前的系統，最新一代SureFIELD全球裝置能夠匹配更高帶寬，重新采用NEMA4標準外殼包裝，以對抗惡劣作業環境。

應用案例1
一名操作員通過SureFIELD全球裝置接收到實時反饋，得知一個偏遠井的電潛泵由于電機過熱沒有排量，且有損壞風險。憑借SureFIELD通信裝置，操作員工遠程關井，避免了電潛泵的進一步損壞。
應用案例2
另一個實例是操作員的井站安裝了SureFIELD全球系統與貝克休斯智能井系統（IWS）。一口偏遠井的SureFIELD井下傳感器檢測到水侵。操作員利用SureFIELD全球通信功能遠程調整閥門設置并且在水進入處理設施前使其得到控制，省卻了派人員到現場調整閥門的過程。
當前，油氣田開發已進入數字油田階段，數字油田的應用領域不斷擴大，技術持續發展，應用情景日趨廣泛。據介紹，通過應用智能井、綜合生產模型、監控系統和生產優化等技術，數字油田可以有效地減少井數及非生產時間，提高設備利用率及油井動態響應程度，優化地面開發及物流管理，最終達到增加產量、降低運營成本、提高生產效率和安全性等效果。從統計數據看，數字油田的應用通?？梢允共墒章侍岣?~6個百分點，使產量提高2%~8%。
The Baker Hughes SureFIELD? Global remote data acquisition device and communication tool gathers and transmits real-time data from sensors and surface controllers at the wellsite, enabling continuous, remote well-monitoring from any connected location. The device is a part of our Production Decision Services (PDS) portfolio, and it can be used in wells without existing monitoring systems, or in wells with existing SCADA systems to enhance data recovery from downhole instrumentation. The SureFIELD Global device integrates a controller with a satellite modem, allowing it to report data via satellite at preconfigured time intervals, or on demand 24/7.
?When the system is in place, operators gain access to real-time production data including feedback from electric submersible pumps (ESPs), distributed temperature sensing (DTS), permanent pressure/temperature gauges, and flow meters. The device also can be used to increase production by enabling secure, two-way remote control of production devices at the well.
?Two examples may help to illustrate how the SureFIELD Global device can work in the field:
An operator received real-time feedback from the SureFIELD Global device that their ESP at a remote wellsite was near a no-flow condition with an overheated motor, and was in danger of failure. Using the SureFIELD Global communication device, the operator remotely stopped the well and saved the ESP from a critical failure.
In another example, an operator had a SureFIELD Global system installed along with a Baker Hughes intelligent well system (IWS). SureFIELD downhole sensors at the operator’s remote well began to detect and communicate a water breakthrough event. Instead of sending personnel out to the well to adjust the valve, the operator used the SureFIELD Global communication function to remotely change the valve setting and control the water before it reached the processing facility.
The SureFIELD Global device is part of the reliable Baker Hughes SureFIELD portfolio. Other key components of the portfolio are the SureFIELD DataHub SCADA system and the Vision web-based monitoring system for data viewing, trending, and alarming. Data gathered by the SureFIELD DataHub device is processed, buffered, compressed, and then transmitted by the SureFIELD Global communication device. The data are then displayed using the Vision user interface on a PC or laptop. This latest generation SureFIELD Global device has higher available bandwidth than previous systems, and it is repackaged in a NEMA 4 enclosure for protection against harsh environments.
