垂直钻井技术能够十分有效地控制井斜,并能够提高机械钻速。在川东北、鄂西渝东地区钻井施工中,垂直钻井技术特别适用于陆相上组合易斜井段施工,不仅能够将上部井眼防斜打直,减少因井眼轨迹复杂而导致井下复杂和事故发生,还能大幅度提高机械钻速。江汉钻井首次在瑞参1井使用垂直钻井技术,该技术对瑞参1井陆相地层防斜打直和提高机械钻速都起到了良好效果,现将垂直钻井技术在该井的应用情况作分析总结。
Vertical drilling technology is very effective in controlling well inclination and can increase ROP. In the drilling of northeastern Sichuan and western Hubei and eastern Chongqing, the vertical drilling technology is especially suitable for the combination of easily inclined shaft sections on the continental facies, which can not only prevent the upper wellbore from slanting and straightening, but also reduce the complexity caused by complicated borehole trajectories. And accidents, but also greatly improve the ROP. Jianghan Drilling for the first time in Rui 1 wells using vertical drilling technology, the technology of Ruishi 1 well anti-stratification stratospheric strata and improve the penetration rate have played a good effect, now the application of vertical drilling technology in the well for analysis Summary.
