摘要: 为了快速检测钻井过程中的井筒压力和温度分布,从而对井涌、井漏和钻具磨损等各类井下故障进行判断和预测,进行了微芯片示踪器研究攻关。采用微型化采集技术、高效电源管理技术和高温高压封装技术,设计研制了小尺寸、低功耗井下数据采集系统——微芯片示踪器样机。该示踪器连续投放到循环的钻井液中,可以快速采集井筒中的压力和温度数据,获得井筒温度、压力分布剖面。微芯片示踪器原理样机直径只有20 mm,地面测试表明,该样机可连续采集到养护釜中100 ℃以下的温度变化,以及20 MPa以下的压力变化。这表明,利用微芯片示踪器可以采集到井筒中的压力和温度数据,建立井筒压力和温度分布剖面。Abstract: The microchip-tracer technique was developed to quickly test temperature and pressure over the entire borehole while drilling,so as to identify and predict downhole complicated conditions,such as kick,lost circulation,drilling string worn and so on.The prototype tracer is small in size and low in power consumption by adopting micro-system of data acquisition,power supply and management,high temperature and pressure resistant package.It can be continuously put into circulating drilling fluids for real-time measurement of temperature and pressure over the entire borehole.The size of tracer is only 20 mm in diameter,and it can detect temperature and pressure below 100 ℃ and 20 MPa in ground test.The research shows that the tracer is a very important tool to detect engineering parameters,and plot the curves for these parameters.
