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.

Key words: MPD, drilling technology, measurement while drilling, bottom-hole flux
