摘要
玉北地区是中石化塔里木盆地会战的一个重要区域,二叠系和石炭系是制约玉北地区钻井提速提效的关键井段。分析了扭力冲击器在玉北地区三开井段适用性,并在玉北1区开发井和风险探井进行现场试验,与邻井相比,开发井钻速可提高191%,可节约1～6只PDC钻头。与上下邻井段相比,风险探井扭力冲击器单趟钻钻井进尺比上下邻井段提高5.42倍,钻速提高270%。最后提出扭力冲击器存在问题及改进措施,为玉北地区扭力冲击器推广应用提供技术支撑。
Adaptability of torsion impactor in Tarim Yubei area was analyzed,and field tests in development well and risk exploration well were proceeded.Comparing with adjacent well,penetration speed in development well could be enhanced by 191%,and 1~6 bits could be saved.Comparing with upper and lower adjacent layer,bit average footage in risk exploration well could be enhanced by 5.42 times,and penetration speed could be enhanced by 270%.Finally,the existent problems and innovative approaches of torsion impactor were proposed.
