钻进式井壁取心器在目的层位处先撑开推靠臂将仪器紧贴井壁,然后金刚石空心钻头在马达的带动下高速旋转垂直钻入井壁来获取岩心。胜利油田自2006年引进FCT型钻进式井壁取心器,在直井中取得了较好的应用效果,但在斜井中由于易产生电缆吸附及钻头伸出位置未能贴紧井壁,造成取心收获率大大降低。本文通过对仪器推靠方式及工艺等改进来提高钻进式井壁取心器在斜井中的取心收获率,以适应油田勘探开发的需要。 Drilling sidewall borescope at the destination level at the first prop to open the arm pushed the instrument close to the wall, and then hollow diamond drill driven by the motor at high speed vertical drilling into the wall to get the core. Since 2006, Shengli Oilfield has introduced FCT-type drilled wall core take-off, which has achieved good results in vertical wells. However, due to the problems of easy cable adsorption and bit extension, Coring harvest rate greatly reduced. In this paper, we improve the coring rate of drilling borehole goggles in inclined shafts through the improvement of the way of pushing the instrument and the process to adapt to the needs of oilfield exploration and development.
