摘要: 水平井在提高油气井产能方面具有明显优势,但受油藏非均质性影响,在边底水油藏或水驱油藏的开发过程中水平井出水情况较为常见,给油田高效开发带来巨大挑战。因此,有效的找水和堵水技术是改善水平井开发效果的重要手段之一。针对水平井出水识别难的问题,全面总结了动态验证、机械找水、测井找水和示踪剂找水等水平井找水方法的特点和现场应用情况,并对水平井找水、堵水方法存在的问题及发展方向进行了分析。该研究可为高含水低效水平井找水和堵水工作提供借鉴。

Abstract: Horizontal wells have obvious advantages in increasing the productioncapacity of oil and gas wells, but influenced by the non-homogeneity of the reservoir, the water breakthrough from horizontal wells is more common during the development of edge and bottom water reservoirs or water drive reservoirs, which brings great challenges to the efficient development of oil fields. Therefore, effective water detection and water plugging technology is one of the important means to improve the development effect of horizontal wells. To address the problem of difficult water breakthrough identification in horizontal wells, the characteristics and field applications of horizontal well water detection methods such as dynamic verification, mechanical water detection, water detection by logging and water detection with tracers were comprehensively summarized, and the problems and development directions of horizontal well water detection and water plugging methods were analyzed. This study can provide a reference for water detection and water plugging in high water-bearing inefficient horizontal wells.
