摘要
针对在海上区块测试时RD循环阀无法打开、环空压力突降为零、RD取样器取样失败、选阀线密封失封、油套连通等问题,介绍了测试过程中的经验教训,制定改进措施,保证DST作业井顺利进行。
To problems of that the RD circulating valve cannot be opened,the annulus pressure is suddenly to zero,RD sampler is failed to collect sample,elected valve is loss of seal,and tubing and casing is connecting during the well testing process in sea blocks,lessons are introduced in paper and improved measures are made to ensure the DST operating smoothly.
