扭矩环在国内海上油田的首次应用
|
摘要
Φ177. 8 mm尾管作业风险高,早已是钻井行业公认的难题,直到近几年旋转下尾管技术逐渐趋于成熟,才使尾管下入的成功率得到较大提高。而普通套管扣抗扭强度难以满足旋转下尾管作业要求,若使用高扭矩套管则费用昂贵,大幅度增加作业成本。介绍了扭矩环的结构特点、工作原理及使用优势,并在实验室验证了扭矩环多项参数的合理性。为节省成本,首次在国内海上油田引入了扭矩环,且在垦利某油田三口大位移井作业中得到了成功应用。扭矩环不仅解决了常规套管扣无法满足旋转下尾管技术的问题,而且节省近60%的套管成本,为现场安全、高效完成作业提供了有力保障,也为渤海油田的降本增效开发做出了贡献,具有良好的应用前景,值得进一步推广应用。
The high risk of RIH Φ 177. 8 mm liner has long been recognized as a difficult problem in the drilling industry. Until recent years,the development of rotating liner running technology improves the success rate of RIH to target depth. However,the torsion strength of common casing thread cannot meet the requirements of rotating liner while RIH operation. If high torque resistant casing is used,the operation cost will be greatly increased. This paper introduces the structure,working principle and advantages of torque ring,and verifies the rationality of several parameters of torque ring in the laboratory. To save operating costs,the torque ring is introduced into the domestic offshore oilfield for the first time,and has been successfully applied to three extended-reach wells in Kenli oilfield,which achieved satisfying results. The torque ring not only solves the problem that common casing thread cannot meet requirements of rotating liner while RIH operation,but also saves nearly 60 % of the casing costs,and provides a powerful guarantee for the safe and efficient operation on site,which contributes to reduce the cost and improve the benefit for Bohai oilfield. It has a good application prospect and deserves further promotion.
