Abstract

A method for preventing formation of a slug flow regime of a gas-liquid mixture in a non-linear wellbore or a pipeline comprises determining at least one most probable place of fluid slugs development in the wellbore or the pipeline by mathematical simulation based on expected values of the gas-liquid mixture flow and known geometry of the wellbore or the pipeline and mounting a device, in the determined place of fluid slug development, that converts the stratified gas-liquid mixture flow into a dispersed flow.

Claims

exact text as granted — not AI-modified

1 . A method for preventing formation of a slug flow regime of a gas-liquid mixture in a non-linear wellbore or pipeline, the method comprising:
 determining at least one most probable place of fluid slugs formation in the non-linear wellbore or pipeline by mathematical simulation based on expected values of the gas-liquid mixture flow and known geometry of the wellbore or the pipeline, and   mounting a device, in the determined place of fluid slug development, that converts a stratified gas-liquid mixture flow into a dispersed flow.   
     
     
         2 . The method of  claim 1 , wherein a vortex-type device is used as the device that converts the stratified gas-liquid mixture flow into the dispersed flow. 
     
     
         3 . The method of  claim 1 , wherein a twisted-tube bundle device is used as the device that converts the stratified gas-liquid mixture flow into the dispersed flow. 
     
     
         4 . The method of  claim 1 , wherein a mixer-type device is used as the device that converts the stratified gas-liquid mixture flow into the dispersed flow. 
     
     
         5 . The method of  claim 1 , wherein a rotating brush type device is used as the device that converts the stratified gas-liquid mixture flow into the dispersed flow.
