摘要
为进一步提高中深井、硬地层钻井速度,大港油田在段六拨、孔南等4个区块8口井的部分井段应用了自激振荡式冲击钻井工具进行钻井试验。现场施工表明,该工具性能稳定,质量可靠,应用井段机械钻速提高了14.2%-132.63%。这表明应用自激振荡式冲击钻井工具基本能够满足提高钻井速度的要求,但为了充分发挥该工具的提速性能,应分析该工具的最佳适用条件。
In order to further improve the drilling speed in hard formation of medium deep wells in Da- gang Oilfield,the self-oscillation impact drilling tool was used in 8 wells in 4 blocks including Duanliubo, Kongnan 4, etc. The test results show that the tool, stable in performance, and reliable in quality, increased the ROP by 14.20%- 132.63%. This showed that the application of the self-oscillation impact drilling tool could basically meet the requirement of improving ROP,but in order to take full advantage of the tool, the best applicable conditions of the tool should be further investigated.
