| Abstract: | According to the characteristics of the coalbed methane development, we developed a solution of flow-concentration and non-flow-concentration measurement. We designed and produced the piezoresistive pressure sensor, the flowcapacity watercut meter and the differential pressure sensor. Through the gas-water two-phase-flow experimental study,we investigated the response rules of the sensors and then devised a new interpretation method under the gas-water twophase-flow condition. Our research proved the feasibility of the above measuring method and sensing technology forthe coalbed methane production profile. |
