Abstract: 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.

Key words: bottom-water reservoir, plugging agent, water coning, oil well
