| 中文摘要:玛页1井是新疆油田股份公司在准噶尔盆地西部隆起乌夏断裂带部署的一口风险探井，目的是探索风城组页岩油和常规高孔火山岩油藏的勘探潜力，全井设计取心275 m，实际取心445 m，该井具有取心井段长、致密泥岩地层取心效率低、裂隙发育段易堵心等特点。针对该区域地层特点及玛页1井长井段取心面临的技术难点，通过应用KT216型钻具长筒取心技术，配套井底动力高转速驱动金刚石钻进工艺，与邻井相比，玛页1井长井段取心钻进综合效率提高1.79倍，连续取心长度445 m，单回次取心长度41.97 m，创该区域历史最高纪录，可为后续该区域长井段连续取心实施提供参考和借鉴。 |

| Abstract:Well Maye-1 is a venture exploration well deployed in the Wuxia fault zone of the Western uplift of Junggar Basin by Xinjiang Oilfield Company Limited. The purpose is to explore the prospecting potential of shale oil and conventional high porosity volcanic rock oil reservoirs in Fengcheng Formation. The designed coring length of the whole well was 275m with the actual coring length of 445m. The well is characterized with long coring interval， low coring efficiency in tight mudstone formation， easy core jamming in fracture developed sections， etc. In view of the formation characteristics in the area and the technical difficulties faced by the long coring interval of Well Maye-1， the long barrel core drilling process with the KT216 tool was applied in combination with diamond drilling at high RPM driven by bottom hole power. Compared with adjacent wells， Well Maye-1 had an increase of 1.79 times in comprehensive drilling efficiency over the long coring interval with the continuous coring length of 445m and the coring length per run of 41.97m， setting the record in the history of the area. It can provide reference for the subsequent implementation of continuous coring over long well sections in the area. |
