摘要：“并工厂”在石油开采中已得到广应用，特别是非常规油气资源的勘探和开发，能实现钻完并批量化和流水线施工，有效提高作业效率，降低作业成本。但由于并间距普遗较小，直井投轨迹受诸多因素影响不能完全钻直，与邻并的碰撞风险很了设计的最小并间距与纠斜点处的并斜角、水平位移以及允许的最大狗隧度等因素间的关系；提出了在直井段允许的最大狗隧度和水平住移的限制条件下对井斜的控制要求。以X平台的式并为例，说明了如何限制丛式并直并段的井斜和水平位移，以及当硅撞风险出现时如何采取纠斜控制措施防硅，

Abstraet: The ‘well plant' mode has been widely used in oil exploitation, especially in the exploration and development of uncon-ventional oil and gas resources. With this mode, batch drilling and completion can be achieved in an operation line, so that operation efficiency is improved and operation cost is reduced. When this mode is applied, however, the well spacing is generally small, and the vertical section can not be maintained adequately due to many factors, leading to high risks of collision between wells. In this paper, it is proposed that vertical section should be drilled with both inclination and horizontal displacement strictly controlled in order to ensure the safety of well drilling in the 'well plant' mode. The relationships between the designed minimum well spacing and the inclination and horizontal displacement at the straightening point or the maximum allowable dogleg severity were discussed, and the control require aaeds eoo pe aaaas aop aoe ne o esn a apn aod se oe o a cluster well on X-Pad was taken as an example to illustrate how to control the inclination and horizontal displacement of vertical section of cluster well and what straightening measures to be taken when any collision may occur.
Key words: drilling; well plant; vertical section; hole trajectory; anti-collision
