摘　　要：方正区块是大庆油田的易斜区块之一,蕴含较大的资源潜力,是大庆油田重要的资源接替区。由于此区块地质构造复杂、地层倾角大、岩性变化大、岩石可钻性级值高以及钻井方式单一、技术措施不完善等因素的存在,井斜问题十分突出,机械钻速较低,严重制约了勘探开发步伐的加快以及钻井技术的快速发展。通过在方23井进行液动旋冲工具,有效提高了机械钻速,保证了井身质量,达到了优快钻井的目的。Fangzheng block is one of the easily inclined blocks in Daqing oilfield, which contains great resource potential and is an important resource replacement area in Daqing oilfield. Because the geological structure of this block is complex, there are many factors, such as large dip angle, large lithology variation, High rock drillability and single drilling mode, imperfect technical measures and so on, the problem of well deviation is very prominent,and the speed of mechanical drilling is low, which seriously restricts the speed of exploration and development and the rapid development of drilling technology. By using hydraulic torque impactor in the Fang 23 well, the mechanical drilling speed is effectively improved, the quality of the well body is ensured, and the aim of the excellent and fast drilling is achieved.
