| 摘 要： | 在常规钻井和欠平衡钻井的基础上发展起来的控压钻井（MPD）技术已经在国内外一些地区的实际应用中取得了良好效果。介绍的井下流量测量装置采用节流压差法，接在近钻头处，能够随钻监测井下环空流量，并通过随钻测量技术（MWD）把数据及时传至地面进行分析处理，可以及早发现溢流或井漏等井下复杂情况。该技术与现有控压钻井系统结合，能够显著提高系统的控制精度和可靠性，从而提高钻井的安全性及降低钻井成本，为安全可靠地进行控压钻井提供保障。

| Abstract: | With the development of drilling technique，a new technique called managed pressure drilling (MPD) has been developed on the basis of conventional overbalance drilling and UBD abroad in the past few years.This technique has already been applied in some oil fields home and abroad up to now and this technique has a good performance.But as a new technique，MPD still has some problems in theory and hardware to solve.This paper introduces a new bottom-hole flow meter which can measure the annular flux while drilling and monitor overflow and circulation loss as early as possible.Applying the device to MPD can improve the accuracy and reliability of the system obviously，thereby enhance the safety of drilling and reduce the cost. |
