摘　　要：井身结构设计不仅关系到安全钻井,而且对钻井提质增效有着特别重要的意义。通过分析柴达木盆地生储地质特点和典型复杂深井案例,突破以必封点和双压力剖面为基础的传统井身结构设计理念,以井身结构设计与实现设计的统一为问题导向,创新提出井身结构多向融合设计方法思路,对技术与管理的融合、钻前与钻中钻后全寿命周期的融合、地质与工程的融合、井身结构与钻井工艺的融合进行相关分解,使井身结构配套设计进一步细化完善。The design of well structure is not only related to safe drilling,but also of great significance to improve drilling quality and ef⁃ficiency.By analyzing the geological characteristics of source and reservoir in Qaidam Basin and typical complex deep well cases,breaking through the traditional wellbore design concept based on the"must seal point"and"double pressure profile",taking the unifi⁃cation of well structure design and realization design as the orientation,the multi-directional integration design method of well struc⁃ture is proposed,and the design of well structure is decomposed in order to achieve the integration of technology and management,the integration of pre-drilling,in-drilling and post-drilling,the integration of geology and engineering and the integration of well structure and drilling technology and to further refine and improve the matching design of well structure.
