| 中文摘要:我公司首次由地质岩芯钻探进入石油钻探领域，在敦化1、2井的失败中吸取经验教训，研制出了钾盐-聚合物钻井液，并在吉林伊通、农安2个矿区约2375 m的钻探施工中，孔壁稳定，孔内无事故，钻进效率显著提高的情况下，岩芯采取率均达98％以上。我公司在吉林壳牌公司油页岩勘探中主要存在泥岩、砂岩、页岩、粘土岩这四种类型的地层，且层位厚薄不均，各岩层互换频繁（0~1000 m换层58次之多），均为较软的、水敏性强的地层，要想顺利钻进，泥浆的性能是成败的关键。 |

| Abstract:Our company undertakes one oil shale exploration project of the Shell Companies in Jilin; this is the first time to get in the oildrilling filed from geologic core drilling for our company.The main rocks in this mining area are mudstone, sandstone, shale and clay rock. They are uneven thickness, changing frequently, soft and strong water senstivity. The key for successfully drilling is mud system and performance. After failed drilling No.1 and No.2 well of Dunhua, we developed a potassium salt / polymer drilling fluid, and applied to the Jilin Yitong, Nonga mining area and finished about 2375 meters. In the process of drilling, the well wall is stability, no drilling burying accident. We got higher drilling efficiency and better engineering quality. |
