摘　　要：南海东部某油田为生物礁滩灰岩油田,内部断层、裂缝发育,地层水通过裂缝、断层进入井筒,油井含水迅速上升,急需采用有效的控水、堵漏措施实现稳产。本文以A井为例,介绍了一种水平井断层控水、堵漏工艺技术,最终实现降低含水、封堵断层、提高采收率。An oilfield in the east of the South China Sea is an organic reef shoal limestone oilfield.Internal faults and fractures are developed,through which formation water enters the wellbore and the water cut in the oil well rises rapidly.Therefore,effective measures for water control and plugging are urgently needed to achieve stable production.Taking Well A as an example,this paper introduces a horizontal well fault water control and plugging technology,and finally realizes reducing water cut,leaking stoppage fault and enhancing oil recovery.
