摘要
Staircase horizontal well is one way of horizontal well development, it has longer section and more control area, and it also can simultaneously mine different oil layers. Starting from the difficulties in well trajectory control and taking well Jin 31-Ping 2 as an example, this paper introduced the geological design and well trajectory design schemes with the well trajectory control idea and methods. By the analysis on the key technology, the implementation focus and the supporting technical measures for staircase horizontal well were described.
