针对新疆油田莫北116井区第一口水平井MBHW602井水平段侏罗系三工河组,采用了保护储层无粘土有机盐钻井液,并在完井后进行储层近井壁解堵。现场应用表明,该钻井液流变性良好,高温高压滤失量小,储层保护效果好;机械钻速与设计相比大幅度提高了50%以上,产能较邻井有较大提高。该钻井液的成功应用为该地区的水平井保护储层钻完一体化提供了宝贵的经验。
Aiming at the Sangonghe Formation of Jurassic in the horizontal section of the first horizontal well in the Mobei 116 well in the Xinjiang Oilfield, the clayey organic salt drilling fluid was used to protect the reservoir and the near wall lining was removed after completion of the well . The field application shows that the drilling fluid has good rheological properties, high temperature and high pressure filtration loss, and good reservoir protection effect. The ROP is greatly improved by more than 50% compared with the design, and the productivity is greatly improved compared with the adjacent wells. The successful application of this drilling fluid has provided valuable experience in the integration of drilling and completion of horizontal well protection reservoirs in the area.
