文章就美国康诺可公司CDR_(102)减阻剂在铁大线熊岳一复县段的试验工作及鞍山等输油站的实际应用情况作了如下的总结:介绍了CDR_(102)减阻剂的物理性能、减阻机理,同时也指出介质的流动状态、粘度、流体温度、含蜡量、含水量以及介质被剪切、节流等情况对CDR_(102)减阻剂减阻性能的影响。文中,还对减阻剂注入点的选择、注入流程、注入形式、注入设备、试验步骤及方法等方面作了较详细的介绍。文章最后,对试验参数、减阻效果(摩阻下降情况、增输效果的数据及有关曲线等)、减阻率和增输率的计算等方面作了重点的分析和解释。另外,将鞍山等输油站进行的生产性注入给予了评估:CDR_(102)减阻剂的减阻、增输的效果虽然较好,但由于其价格昂贵,因此,它仅作为短时间处理个别卡脖子段的应急才有其优越性。鉴于我国原油多为高凝高粘的状况,指出对化学添加剂的研究和技术开发是必要的。
The article summarizes the experimental work of Connaught Corning CDR_ (102) DRA in the Xiong Yue-Fu County section of Tie Daban and the practical application of Anshan gas station as follows: The introduction of CDR_ (102) The physical properties and drag reducing mechanism of the dragging agent are also pointed out. The drag reduction performance of the CDR 102 drag reducer is also pointed out, such as the flow state, viscosity, fluid temperature, wax content, water content and medium cutting, Impact. In the article, we also introduce the drag point injection point selection, injection flow, injection form, injection equipment, test procedures and methods in detail. Finally, the article analyzes and explains the test parameters, the drag reducing effect (the decrease of friction drag, the data of increasing transmission effect and related curves), the drag reduction rate and the calculation of transmission rate. In addition, the productive injection at Anshan oil station was evaluated: CDR_ (102) drag reduction drag reduction effect, although the increase is good, but because of its high price, so it only as a short treatment Individual card neck section of the emergency has its advantages. In view of the fact that crude oil in our country is mostly hypercoagulable and highly viscous, it is pointed out that it is necessary to research and develop chemical additives.
