Technology for eccentric quantitative early separate injection in deep deviated wells;

深斜井偏心定量早期分注技术

The well A4 of Pinghu oil and gas field is a high deviated and deep well with total depth of 3113 m and maximum inclination of 59°.

在第一次套铣作业失败后,对套铣工艺参数影响因素进行了分析,在此基础上选择合理的钻压、转速、排量和泵压等套铣工艺参数,对A4井永久式封隔器重新套铣获得成功,解决了大斜度深井处理丢手管柱的技术难题,也为今后类似作业提供了经验。
