在油田的不断开发中 ,老井井况问题日益突出 ,直接影响了油田的持续稳产。部分老井受断层影响 ,钻遇油层少 ,或主力油层水淹 ,严重影响了老井开发效益。为了提高老井的利用率 ,减少投资 ,将小井眼开窗侧钻技术应用于—文东文中油田。经送斜、固斜 ,在 139.7mm套管上开窗。采用套管悬挂器 ,由窗口处下 10 1.6mm套管完成。该项技术应用的成功 ,不仅解决了无法修复的老井再利用问题 ,同时也增加了可采储量 ,成为断块油田开发后期稳产的一种有效手段。
In the continuous development of the oilfield, the well condition of the old wells has become increasingly prominent, which has a direct impact on the sustained and stable production of the oilfield. Part of the old wells affected by the fault, drilling fewer oil reservoirs, or the main reservoir flooding, seriously affected the development of old wells benefit. In order to improve the utilization rate of old wells and reduce investment, the application of Slim Hole Side Window Drilling Technology - Wen Dongwenzhong Oilfield. The oblique, solid oblique, 139.7mm casing on the window. Using a casing hanger, complete with a 10 1.6mm casing at the window. The successful application of this technology has not only solved the problem of re-utilization of old wells that can not be repaired, but also increased the recoverable reserves, making it an effective means for stable production in the late block oilfields.
