吐哈盆地红连边底水油藏高效开发实践与认识

The practice and understanding of highly efficient development of Honglian edge - bottom water reservoir in Tuha Basin

针对小型块状边底水油藏特征,编制了适合油藏特点的开发方案,在开发实践中不断加深认识,合理调整,探索出低含水期控制液量、中含水期油水同采、高含水期老井侧钻、关井压锥等有效防治扣治理底水锥进的新方法,形成了小型边底水油田开发的成熟技术,实现了油田高速高效开发,为今后同类型油田的开发提供了借鉴。

A development plan is made according to the characteristics of small block edge - bottom water reservoir. New methods for preventing and treating bottom water coning are found out through deeper understanding of the development practice and rational adjustment, which are to control liquid production in low water cut period, to produce oil and water simultaneously in medium water cut period, and to drill side - track well or to shut well down to kill coning in high water cut period. These development technologies are mature for small edge - bottom water oilfield, thus realized highly efficient oilfield development and provided reference to similar oilfield.
