| 摘 要： | 针对川东地区高陡构造高地层倾角井井眼轨迹控制难度大,并且上部自流井群泥页岩极易发生垮塌等特点,提出应用VTK(VertiTrak)垂直钻井技术防斜打快,并配合使用活度平衡防塌钻井液,以确保井眼稳定和VTK设备安全.介绍了钻井液体系的选择思路和配方的优选.天东004-X3和板东006-H1两口试验井通过应用该技术,平均机械钻速比邻井相同层位提高了57.1％以上,钻井周期缩短了6.1 d,表明VTK垂直钻井技术在高陡构造高倾角井和易斜地层能有效控制井斜,实现直井段的防斜打快、提高机械钻速,配套的活度平衡防塌钻井液具有“强抑制、平衡滤液活度、超低渗透”特性,能有效解决易塌泥页岩地层的井眼稳定问题,并成功实现化学防塌,较大幅度地降低了钻井液密度. |
| 关 键 词： | 高陡构造 井斜控制 VTK垂直钻井 防塌钻井液 活度平衡 井塌 |

| Abstract: | In the formation of high steep structure East Sichuan,challenges of hard to control well track and clay caving in top Ziliujing strata are encountered.The technology of VTK (VertiTrak) drilling technology is applied to drill vertical and fast,and the drilling fluid system of balanced activity anti-caving is used to keep borehole stable.The applications of the technologies in well Tiandong004 and well Bandong006-H 1 show that the average ROP increases by more than 57.1%,the drilling period decreases by 6.1 d... |
| Keywords: | High steep structure Well track control VTK vertical drilling Anti-caving drilling fluid Balanced activity Hole collapse |
