摘要:
连续管在水平井施工作业时,特别是长水平段、超长水平段、井眼轨迹弯曲、上翘井,常因自身螺旋锁定,出现不能到达目标深度、钻磨钻压难以加载等问题,严重影响施工进度和施工质量。为解决连续管下入自锁的问题,对标国外水力振荡器,对定转子的线形进行了优化,自主开发研制了一种水力振荡器。室内测试结果表明,该水力振荡器的压降为2~5.4 MPa,达到了设计要求。该水力振荡器在威X井进行了现场对比试验,各项指标满足设计和使用要求,降低了井下管柱在前进中的摩擦阻力和扭矩,有效传递了钻压,增加了连续管的下入深度。在川渝地区现场使用249井次,效果显著,能有效缩短施工周期,提高施工质量。该水力振荡器实现了国产化,打破了国外技术垄断,缩短了供货周期,节约了成本。
Abstract:
During construction of coiled tubing in horizontal wells, especially in wells with long horizontal section, ultra long horizontal section, curved wellbore trajectory and upturned wells, problems such as unable to reach the target depth and difficult loading of drilling bit pressure etc. often occur due to its own spiral locking, which seriously affects the construction progress and construction quality. In order to solve the problem of coiled tubing running in self?ocking, a hydraulic oscillator is independently developed by benchmarking with foreign hydraulic oscillators and optimizing the alignment of stator and rotor. The indoor test results show that the pressure drop of the hydraulic oscillator is between 2~5.4 MPa, which meets the design requirements. The hydraulic oscillator has carried out field comparative test in well Wei X, and all indexes meet the design and application requirements, reduce the friction resistance and torque of downhole string, effectively transfer the bit pressure and increase the running depth of coiled tubing. The field application of hydraulic oscillator 249 wells has remarkable effect in Sichuan and Chongqing, which can effectively shorten the construction period and improve the construction quality. The hydraulic oscillator has realized localization, broken technical monopoly of foreign companies, shortened supply cycle and saved costs.
