摘要
针对稠油井测试工艺存在的问题 ,对稠油井测试工艺进行了改进和完善 ,认为用液氮可以控制压差。测试选APR工具 ,测试管串不下检漏压力计 ,割缝筛管改为打孔筛管 ,可以提高稠油在管串中的流动速度 ,提高参数计算准确率。改进后的工艺在现场应用中取得较好成效。
To problems of testing in heavy oil wells,the improvement and completion of testing technology have been conducted by hydraulic nitrogen to control pressure difference.By the way of selecting APR testing tools,without using monitoring gauge and changing slotted pipe to perforated one,flowing velocity of heavy oil in strings can be raised and calculating accuracy of parameters has been upgraded.The developed technology had a good effect in field applications.
