FN2ST是苏丹的第一口小井眼侧钻井,由长城钻探提供侧钻开窗、定向和扩孔完井技术一整套服务。小井眼侧钻井由于环空间隙小,尾管不居中,固井顶替效率低,造成水泥环薄而影响固井质量。具有自主知识产权的长城侧钻扩孔完井技术已在国内应用数千口井次,有效地解决了上述技术难题,节约了大量成本,积累了丰富的施工经验。而在苏丹6区施工尚属首次,该井的作业成功彰显了长城侧钻井技术服务的实力,同时开拓了小井眼侧钻市场,具有广阔的应用前景。
FN2ST is Sudan’s first slimhole hole-side drilling provided by Great Wall Drilling with a complete set of sidetracking and windowing, directional and reaming completion technologies. Because of the small annulus clearance, the tail pipe is not centered, the cementing displacement efficiency is low, causing the cement ring to be thin and affecting the cementing quality. With the independent intellectual property rights, the Great Wall Drilling Reaming Technology has been applied thousands of times in the country, effectively solving the above technical problems, saving a lot of costs and has accumulated rich experience in construction. For the first time in Sudan, construction in Zone 6 is the first time that the well’s operation successfully demonstrated the strength of the Great Wall Side Drilling Technology Service and at the same time opened up the market for the slim hole drilling and has broad application prospects.
