摘要
The problems possibly occurred in the coal bed methane (CBM) well measurement are analyzed. An extrinsic Fabry Perot (F-P) interferometer (EFPI) is used as a new direction of liquid surface measurement in coal bed methane well. A liquid surface measuring system on the EFPI is developed to fundamentally solve the difficult problems of the accurate level in the coal bed methane well. The relative error of optical cavity length is 1.48% and resolution is 1 μm in the measuring system, which is obviously more effective than the traditional measuring technologies.
