| 摘 要： | 对Daleel油田作业5区三分支水平井DL-59井井下复杂情况分析,室内测定了引起复杂情况的Nahr Umr泥页岩地层的矿物组分和粘土矿物含量,优选了适应在该泥页岩地层215.9 mm造斜井段的钻井液配方中的各种处理剂,最后研制出钻井液配方,通过DL-73井应用后,取得了良好的防塌效果.

| Abstract: | This paper analyzes the complicated downhole conditions of well DL-59, a horizontal well with three laterals,in Block 5 of Daleel Oilfield.The mineral composition and clay mineral content of Nahr Umr mud shale formation,which is the cause of the complicated conditions,are measured in-house.Treating agents in drilling fluid formula are optimized for the 215.9 mm build-up interval in the mud shale formation.The application in well DL-73 has shown good anti-sloughing effect. |
