- 摘要:
- 分析了传统的清管球(器)收球工艺流程及其存在的主要问题,如过球指示器不能准确反映清管球是否通过、清管球达到时间计算不准确、常规三通挡条不能承受较大压力等,在此基础上提出了双挡条三通的收球工艺流程方案,并进行了实验模拟验证。新收球工艺流程能解决原存在问题,可避免收球过程中的卡球事故发生,为海底管道和陆上长输管道的收球流程设计提供了有益的借鉴。
The traditional process of receiving pig and its main shortages, such as pig pass indicator mal-function, inexact pig arriving time calculation and breakage of steel blocking bars in T-valve under largepressure were analyzed. Therefore, a new process design of two T-valves with steel bars in pipeline was developed,and the simulation experiment was performed. This process design can solve the original problems and avoideffectively the pig blockage incident. The optimized design provides a reference for pig receiving process design of subsea pipeline and land long-distance pipeline.2010,2(2): 26-27 收稿日期:2009-4-22分类号:TE973.6作者简介:王玉(1975 -),男,辽宁昌图人,工程师,1998年毕业于中国石油大学(北京)石油工程专业,从事海上油田的生产管理工作.参考文献:
