新型连续管侧钻装备可行性研究

Feasibility study on one new coiled tubing sidetracking equipment

连续管侧钻技术凭借其一系列优势在国外得到了广泛的应用,但国内至今没有大规模推广。通过对比分析国内外连续管侧钻装备进展,发现国内与国外的差距还非常大。为早日实现国内连续管侧钻工艺的规模化应用,需要研发配套更适合我国国情的连续管侧钻装备。长城钻探井下作业公司技术团队经过对连续管侧钻装备关键部件的优化设计后提出了一种“1+1+1”三模块组合方案,即:连续管设备模块+液压举升机模块+辅助设备模块。该方案将三个单独的模块有效的统一起来,既能联合作业,也能够单独作业。具有占地小、价格低、安装组合快、操作简单、工序转换时间短等优势。通过与常规修井机和裸眼连续管钻机的比较,可知:液压举升复合连续管钻机在生产时效、作业成本等方面均优势明显,具有较大的推广价值。但该装备配套方案尚未付诸实施,还需要进一步的研究和试验。

By comparing and analyzing the development of coiled tubing sidetracking equipment at home and abroad, it is found that the gap between home and abroad is still very large. In order to achieve the large-scale application of coiled tubing sidetracking technology in our country, it is necessary to develop the support equipment which suits the situation of our country. The technical team of the Great Wall Drilling Company proposed a "1+1+1" three-module combination scheme after optimizing the key components of coiled tubing sidetracking equipment, namely: coiled tubing equipment module + hydraulic lifting machine module + auxiliary equipment module. The scheme will effectively unify the three separate modules, which can not only work together, but also work alone. It has the advantages of small area, low price, quick installation, simple operation and short process conversion time. Compared with conventional workover rig and open-hole coiled tubing rig, it can be seen that hydraulic lifting composite coiled tubing rig has obvious advantages in production time, operation cost and other aspects, and has great popularization value. However, the equipment package has not yet been put into practice, and further research and tests are needed.
