金31-平2阶梯式水平井井眼轨迹控制技术

Well Trajectory Control Techniques for the Staircase Horizontal Well Jin 31-Ping 2

摘要:

阶梯式水平井是常规水平井发展的一个方向，它具有位移更大、控油面积更广的特点，和常规水平井相比，可以同时开采不同层位的油层等。从阶梯式水平井的轨迹控制技术难点入手，以金31-平2井为例，简要介绍了该井的地质设计、井身轨道设计方案，给出了在该井施工过程中各井段井眼轨迹控制思路、方法，通过分析主要工艺技术，阐明了阶梯水平井实施的重点和配套的技术措施。

Abstract:

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 the example of well Jin 31-Ping 2, the 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.
