| 摘 要： | 柴达木盆地油砂山油田地质构造复杂，地层孔缝发育、压力系数低，常规泥浆钻井过程中漏失频繁、钻井周期长，严重制约了勘探开发效益。针对该地区钻井难点，进行了4口井充气钻井试验。试验结果表明，充气钻井能有效解决油砂山油田漏失地层钻井问题，并提高机械钻速，与常规泥浆钻井技术相比，平均节约堵漏时间6.32 d，漏失量减少54.5%，机械钻速提高1.1倍。试验的成功，对该区块优快钻井技术的研究和推广应用具有指导意义。

| Abstract: | Youshashan oilfield is located at Qaidam basin, the complex geological structure, formation cracks development, low pressure coefficients, frequent leakage and long drilling cycle have seriously restricted the exploration and development benefits in conventional mud drilling. In view of these difficulties, aerated drilling tests are carried out in 4 wells, the results show that the aerated drilling can effectively solve the drilling problems in the leakage formation of Youshashan oilfield and improve the POP; compared with conventional mud drilling technology, the average plugging time is reduced by 6.32 days, the leakage loss is reduced by 54.5% and the ROP is increased by 1.1 times. The success of the tests are of guiding significance for the research and application in optimized and fast drilling technology in this block. |
