中原油田钻井四公司在文明寨油田钻成了 3口拔套侧钻井 ,与 139.7mm套管开窗侧钻井相比 ,很好地解决了小尺寸钻头机械钻速低和小井眼固井质量差两大难题 ,开辟了油气井大修新途径。文中详细叙述了拔套侧钻工艺技术 ,对今后进一步开展拔套侧钻施工具有一定的指导意义。 Zhongyuan Oilfield Drilling Company 4 drilled 3 pull-out sets of side-drilled wells in Wenmingzhai Oilfield. Compared with the 139.7mm casing open-side drilling, the well of the small-sized drill bit solved well and the poor quality of well-well cementing Two major problems opened up a new way for overhauling oil and gas wells. The paper described in detail the sidetracking technology, which has some guiding significance for the further development of sidetracking in the future.
