随着水平井钻井技术的发展和完善,水平井技术已成为稠油油藏、边底水油藏与薄层油藏开发的重要技术。但水平井生产过程中出水问题已成为制约水平井采油的关键难题。文章调研分析了目前常用的水平井堵剂及堵水工艺,其中聚合物冻胶是其中最常用的堵剂之一,并分析对比各种堵水剂的优缺点,指出了水平井堵水工艺中存在的问题及发展方向。
With the development and improvement of horizontal well drilling technology, horizontal well technology has become an important technology for the development of heavy oil reservoirs, edge water reservoirs and thin-layer reservoirs. However, the issue of water production in horizontal well production has become a key problem restricting horizontal well production. The article investigates and analyzes the commonly used horizontal well plugging agent and water blocking technology, of which polymer gel is one of the most commonly used plugging agent, and analyzes the advantages and disadvantages of various plugging agent, points out the horizontal well plugging technology In the existing problems and development direction.
