高15-19井“上喷下漏”井段的处理方法

Treatment Method of “Upper Blowout and Lower Loss” Section in Well Gao 15-19

摘要:

高15-19井主要表现在上部的高压力溢流层与下部低压力的漏失层压力极为相近，压力窗口小；通过采取一系列的技术措施，最终在安全的前提下完成了本井的施工任务，并在“上喷下漏”长裸眼井段施工的处理方面积累了一定的经验。

Abstract:

In well gao15-19, the pressure was very similar in upper overflow layer with high pressure and lower leakage layer with low pressure, and the pressure window was small; construction was completed by applying a series of technical measures, and the experience was accumulated for such a long open hole.
