Annulus fluid level measurement is one of the important processes in CBM production,and the depth of the fluid level should be frequently and continuously supervised.The paper introduces a new method that can continuously supervise the fluid level variation of the CBM well,as well as the situation of field application and the result of continuous comparison test with underground electronic pressure gauge.The new method can guarantee the accuracy of the fluid level variation,and reach the testing precision as the pressure gauge.It can be one of the candidate plans for fluid level continuous supervision of CBM well.
