| 摘 要： | 青海油田柴达木盆地的尕斯库勒地区属于山前高陡构造易斜地层,长期以来在钻进上部地层时,由于地层自然造斜效应的影响,井斜问题十分严重。在该区块试验中,带液力推力器的井下钻具组合在明显提高机械钻速的同时,使井斜也得到一定程度的控制。而且,钻头在破岩过程中减振效果明显,保护了钻具,延长了钻头使用寿命,缩短了钻井周期,为该区块钻井防斜打快技术的发展提供了新的思路。

| Abstract: | Gaskule Region of Qinghai Oilfield in Qaidam Basin belongs to the steep structure with easy ramp strata.For a long time, the drilling of the region is in the upper part of strata.Due to the effect of natural deviating, well deviation problem is very serious.With hydraulic thruster BHA trial in the region, it is shown that it markedly improved ROP while well deviation is controlled to a certain degree.Meanwhile, the drill bit in the process of breaking rock has obvious damping effect, which has protected the... |
