TP4CH超深侧钻水平井钻探技术

摘要

In order to recover productivity and improve the production of reserve of old well TP4,a casing window side-tracking well,TP4CH,was drilling in Φ244.5mm casing of TP4.This paper introduces the relevant methods such as well profile planning,forging and mil%为恢复老井TP4井的生产,提高储量动用程度,在TP4井的Φ244.5mm套管内开窗侧钻TP4CH井。针对TP4CH开窗侧钻水平井超深、高温给钻井施工带来的困难,介绍了该井钻井过程中井身剖面设计、锻铣、井身轨迹控制、钻井液、安全钻井配套技术等方面所采取的措施。TP4CH井的成功实施,对同类井的钻井设计、施工具有一定的指导和借鉴意义。
