摘要
西南地区的川西坳陷中江鼻状构、高庙子构造井,地层裂缝发育,普遍存在井壁失稳现象,极易产生掉块。同时,长二开裸眼段更加恶化了井壁失稳,井眼条件恶劣,缆测井十分困难。本文通过4口井电缆测井施工实例,总结分析了该地区电缆施工的阻卡原因和适用仪器组合。
Zhongjiang nose structure and Gaomiaozi structure well in Western Sichuan depression in Southwest China,The formation fracture is developed,and the wellbore instability is common,which is easy to produce block fall.At the same time,the open hole section of chang’erkai worsens the wellbore instability,the borehole conditions are bad and the wireline logging is very difficult.This paper summarizes and analyzes the causes of blocking and the combination of suitable instruments in cable logging in four wells.
