干加膨润土粉.作为一种迅速稳定井壁的简易方法,我们在近5年的20余口井获得成功应用。例1:旺29,钻至井深211m时严重井塌,用尽井场所有常规处理剂(CMC、SP等)调整泥浆性能无效:振动筛仍无岩屑返出,方钻杆上下活动不超过5m。最后,将井场仅有的干膨润土粉取1t经漏斗均匀加入井浆中。很 Dry bentonite powder.As an easy way to quickly stabilize the wellbore, we successfully applied it in more than 20 wells in the last 5 years. Example 1: Wang 29, drilled to a well depth of 211m, suffered a serious collapse and used all of the conventional treatment agents (CMC, SP, etc.) at the wellsite to adjust the slurry’s performance. Invalid: the vibrating screen is still free of debris and the drill pipe does not move up and down 5m. Finally, the dry well only bentonite powder 1t through the funnel evenly into the well. very
