查询词典 flow property

On the basis of introducing the working principle and characters of newly made Gas Holdup Tool, the usage of GHT in detecting the gas well production performance is analyzed. Methods are provided for analyzing fluid property, flow status and judging water carriage in gas wells by integrating the logging data obtained from traditional densimeter and the new GHT. Based on the characters of different depth in water carried gas wells, a model is established for interpreting the water-carried gas wells.
