DRAG REDUCING AGENTGS FOR MULTIPHASE FLOW |
摘要 |
<p>A process for using high molecular weight, anionic, hydrophilic polymers without formation of deleterious emulsions to facilitate flow in multiphase pipelines containing both oil and water (e.g., oil/water, oil/water/gas, oil/water/solids, and oil/water/gas/solids) such as are used for oil or gas production, gathering, and transmission; hydrotransport of oilsand or heavy oil slurries is described. Specific examples of suitable drag reducing polymers include anionic, hydrophilic polyacrylamides having a molecular weight of greater than 1 megadalton.</p> |
