| 中文摘要:近年来，随着油气勘探开发的深入，大斜度井、水平井的增多，定向井及水平井位移越来越长，遇阻通井现象频频发生，完钻电测一次成功率低，影响了建井周期。本文通过对川西、川东北等地区部分定向井及水平井完井电测遇阻原因分析，从钻井液角度出发，提出“强抑制-交联-固壁”技术、高效润滑段塞技术等相应对策提高电测一次成功率。现场应用表明，这些钻井液技术对策为提高完井电测一次成功率、解决电测遇阻问题提供了新的思路。 |

| Abstract:With the development of oil and gas exploration and the increase of highly deviated wells and horizontal wells in recent years, the displacement is getting longer and longer for directional well and horizontal well, drifting for blocking is frequent, low one-time success ratio of completion logging affects well construction period. Though the analysis on the causes of blocking in completion logging in some directional and horizontal wells of west and northeast Sichuan, the countermeasures of “strong inhibition-cross linking-wall consolidation” and high-efficient lubrication slug technologies are put forward mainly for drilling fluid to improve one-time success ratio of completion logging. Field application shows that these technical countermeasures offer a new way to solve the blocking in logging. |
