摘要
小尺寸双心巴拉斯钻头是139.7mm套管开窗侧钻作业的较理想选择。初步分析了中原油田用这种钻头钻4口小眼井的参数优选、扩眼效果、自然增斜及钻头磨损情况,同时探讨了139.7mm套管开窗侧钻井的井眼轨迹控制、机械钻速及固井质量等问题。
It is a better selection to use small bicenter Ballas bits in sidetracking through φ139.7mm casing with windows.The optimum parameter,reaming effect,natural deflection and bit abrasive during drilling in 4 slimholes with the bits are preliminary analyzed.In the meantime,the problems such as well trajectory control,rate of penetration and cementing quality are also discussed.
