Method for Field Evaluation of Drag Reduction Effect of Natural Gas Drag Reduction Agent
摘要
Abstract
The appropriate use of natural gas DRA can effectively reduce the energy consumption during long-distance trans-portation and improve the capacity of the pipeline. Scientific evaluation of the drag reduction effect is the key to the appropriate use of natural gas DRA in the field. However,there exist some limitations in the drag reduction effect evaluation methods currently used in the field production,thus these evaluation methods cannot meet the need of the pipeline transportation. With consideration of the drag reduction mechanism and the requirements of pipeline transportation,we analyzed and improved the three evaluation methods used at home and abroad,and proposed two new evaluation methods. After comparing the five methods according to the fuzzy comprehensive evaluation theory,we identified the combination of gas transmission efficiency coefficient evaluation and hydraulic friction coefficient evaluation as the most appropriate evaluation method. Based on the research results,we developed a natural gas pipeline DRA drag reduction evaluation software. The test results of the software from the application to a gas pipeline not only agreed well with the actual situation,but also met the need of both the technical officers and the production managers. The software is approved by the field staff as it was simple and easy to use.关键词
