Discussion on the influencing factors of directional well's drilling rate and the measures of increasing it<br>Zhao Hong bin<br>(crew sp281, Kuwait, Yellow River Drilling Company, Sinopec Shengli Petroleum Engineering Company)<br>Abstract: in the drilling construction of directional wells, only by ensuring the drilling speed up to the standard can we lay a solid foundation for the drilling work. However, in the actual drilling construction, it is inevitable to encounter unreasonable drilling speed, which will make the construction be greatly affected, resulting in reduced production efficiency and higher production costs. It is of great significance to strengthen the work of improving the drilling speed of directional wells. In addition, different areas have different landform and geological conditions, which also brings great challenges to directional well drilling construction, and requires higher drilling speed. No matter from that point of view, it is particularly important to strengthen its improvement.<br>[Key words] directional well; drilling construction; drilling speed; influencing factors; speed raising Countermeasures<br>
