一种开发无隔板底水油藏的新方法

在无隔板底水油藏开发过程中,许多油井面临着底水锥进速度快、临界产量低、无水采油期短等生产技术难题。借鉴前人研究思路,基于开发底水油藏的隔板理论和双层完井排液压锥技术,对无(天然)隔板底水油藏的开发模式进行了探讨。提出了一种人为注入堵剂(人工隔板)与排水压锥技术相结合的有效开发无隔板底水油藏的新方法,对于科学、高效、合理开发底水油藏具有一定的现实意义。

A New Method for Development of Bottom-Water Reservoir Without Natural Barrier

During development of bottom-water reservoir without natural barrier, many oil wells are faced with difficulties such as fast bottom-water coning, low critical yield and short water-free oil production period, etc. Based on previous researches, partition theory and the dual completion bottom-water coning control technology, the development model for the bottom-water reservoir without natural barrier is discussed. And a method for effective development of such a reservoir by plugging agent injection (artificial partition) and drainage bottom-water coning control is proposed for the purpose of scientific, efficient and rational development of such a reservoir.
