Abstract

The shape and size of formation cuttings passing through a shaker screen can provide valuable insights about any potential downhole problems. Large size cuttings or carvings may indicate the presence of an abnormal pressure zone and hole size may be enlarged which may lead to NPT events (stuck pipe, loss circulation, etc.), asset loss or HSE incidents. We proposed a new method of real-time automated analysis of cuttings in the shale shaker enabling faster reaction to mitigate risks associated with drilling operations. The solution uses a camera on the shaker screen, capturing the cuttings images and applying computer vision and convolutional neural networks algorithms to identify and classify individual cuttings shape, size and type combined with wireline data to raise alarms on specific conditions and prescribe actions to mitigate the problem. The solution showed a remarkably high confidence in identifying the cutting types and size and in detecting potential problems at their early stage enabling the drilling engineers to take the corrective actions at the onset of an event.
用于钻完井岩屑分析的机器学习/人工智能驱动计算机视觉
通过振动筛的地层岩屑的形状和大小可以为任何潜在的井下问题提供有价值的见解。大尺寸的岩屑或岩屑可能表明存在异常压力区,井眼尺寸可能会扩大,这可能导致NPT事件(卡钻、漏失等)、资产损失或HSE事件。我们提出了一种新的页岩振动筛岩屑实时自动分析方法,能够更快地做出反应,降低钻井作业相关的风险。该解决方案使用振动筛上的摄像头,捕捉岩屑图像,并应用计算机视觉和卷积神经网络算法识别和分类单个岩屑的形状、大小和类型,结合电缆数据,在特定情况下发出警报,并制定措施来缓解问题。该解决方案在识别切割类型和尺寸以及在早期发现潜在问题方面显示出非常高的可信度,使钻井工程师能够在事件发生时采取纠正措施。
