Experimental Study and Model Evaluation on Continuous Liquid Removal in Horizontal Gas Well
摘要
Abstract
The continuous fluid removal of the horizontal gas well is more difficult than that of the vertical wells. To study the problem of the continuous fluid removal of the horizontal gas well,we have simulated the gas-liquid two phase flow of the horizontal gas well with the visual gas-liquid conduit flow experimental device. This device is made up of vertical tubes, which is six meter high,horizontal tubes at ten meters,inclined tubes at six meters long. Through experiments,we found that, among the vertical,horizontal and inclined tubes,the capability of liquid-carrying of inclined tubes is the worst. So,the critical liquid-carrying velocity of the inclined tubes can be used as the velocity of horizontal gas well. Droplet and film model of the inclined tubes are now widely accepted. We observed the phenomena of liquid-carrying and test the critical liquid-carrying velocity in different inclined angles,which are from 28° to 72° The experiments show that liquid in the inclined tubes is carried by film form,not droplet form. From the mechanism analysis,the film model is more reasonable. Contrast the test values with the calculated values of film and droplet model,we can also find that film model is more reasonable.关键词
