摘　　要：针对华北油田勘探开发过程中存在的井身结构复杂、施工难度大等问题,采用快速钻井液技术在华北油田宁古10井、鄚39井进行了现场提高机械钻速试验。结果表明,快速钻井剂与现场所用钻井液体系具有良好的配伍性,对钻井液常规性能及流变性没有影响,有效解决了中上部地层易发生井壁垮塌等问题,使机械钻速显著提高,宁古10井试验井段对应的机械钻速相对上部井段提高了18.4%,鄚39井提高了19%。In light of the problem that there exist complex casing program and difficult operation in the process of exploration and development in Huabei Oilfield, the field experiment was conducted in Ninggu Well 10 and Mao Well 39 of Huabei Oilfield to improve the penetration rate by adopting the quick drilling fluid technology. The result shows that the quick drilling agent has a good compatibility with the field applied drilling fluid system and it has no effect on the normal performance and rheological property of drilling fluid, thus effectively solving the problem that the well wall tends to collapse in the upper and middle formations and improving the penetration rate remarkably. The penetration rate in the testing well section of Ninggu Well 10 was improved by 18.4%,compared with the upper well section; as for Mao Well 39, the speed was improved by 19%.
