摘要: 针对伴生气管线的清管前期准备工作中,清管器选择的恰当与否直接影响清管效果的问题,在介绍了现在常用的3种清管器-橡胶清管球、刚体式皮碗清管器、聚氨酯清管器后,从定性和定量两个方面对清管器的选择进行了研究。定性分析中考虑了运行方向、重量、耐磨性、使用范围和价格等几方面,定量分析采用HYSYS软件对各种清管器在不同清管工况下进行模拟。推荐采用清管球和聚氨酯泡沫清管器组合清管,该方式既可取到良好的清管效果,又可以降低泡沫清管器的磨损,延长其使用寿命,从而提高方案的经济性。

Abstract: The choice of pigging is especially important in the preparations in associated gas pipeline pigging because of its direct impact on pigging effect. Three kinds of common pigging are introduced, i.e., rubber pigging, steel pigging and polyurethane pigging, both qualitative and quantitative analysis of pigging choice are made. Several aspects are considered such as running direction, weight, abrasion resistance, using range and price in qualitative analysis and HYSYS is adopted to simulate in different conditions in quantitative analysis. At last, pigging and polyurethane foam pigging are both proposed for combination pigging since it has good effect and can reduce spoilage of polyurethane foam pigging and prolong lifetime, and the scheme economy is improved thereby.
