【摘要】：马深1井是部署在四川盆地的一口超深井,存在井身质量控制困难、钻井提速难度大、喷漏风险并存、钻井液和水泥浆性能维护难度大、固井质量难以保证等钻井技术难点。为此,根据该井所钻遇地层的特点,充分考虑预探井风险,在保证钻井安全的前提下,兼顾井身质量、效率、经济等因素,将井身结构设计为导管+五开井身结构,设计采用氯化钾聚胺磺化防塌钻井液和胶乳防气窜固井水泥浆,并在实钻中采用气体和泡沫钻井技术、"螺杆+PDC钻头"复合钻井技术、"涡轮钻具+孕镶金刚石钻头"钻井技术及"旋冲工具+PDC钻头"钻井技术等提速技术。该井钻井过程顺利,提速效果明显,表明该井的钻井工程设计合理,所采用的提速技术针对性强,可以解决该井存在的钻井技术难点。
[Abstract]:The horse 1 deep wells in the Sichuan basin is the deployment of a super deep well, difficult wellbore quality control, drilling difficulty, spray leakage risks, drilling fluid and cement slurry cementing maintenance is difficult, it is difficult to guarantee the quality and other drilling technical difficulties. Therefore, according to the characteristics of well drilled stratum, fully considering the pre drilling risk, under the premise of ensuring drilling safety, efficiency, well quality, economic and other factors, the well structure design for five + catheter well structure design using potassium chloride, poly amine sulfonation anti sloughing drilling fluid and solid mud latex anti gas channeling wells, and the gas and foam drilling in the drilling technology, "+PDC screw drill composite drilling technology, the drilling technology of turbodrill + impregnated diamond bit" and "spin tool +PDC drill drilling technology. The drilling speed smoothly, speed effect is obvious, the well drilling The engineering design is reasonable and the speed raising technology is more pertinent, it can solve the drilling technical difficulties in the well.
