本文针对低渗透油田目前存在现井网对砂体控制程度较低,现井网注采难度大,注水压力上升速度快,单井注入量低,低产井比例大的问题,分析全油田的细分注水现状,确定细分注水界限,总结细分注水效果,同时对低产井成因进行基础分析,同时针对不同类型开展了精细措施调整和措施效果分析,提高单井产量高,改善了油层吸水状况,含水上升得到一定控制,改善了开发效果。
In this paper, we present the existing problems in the low permeability oilfield, such as the low control of the sand body, the difficulty of well injection and withdrawal, the rapid rise of water injection pressure, the low single well injection and the large proportion of low production wells. The status of sub-injection of water, determine sub-injection boundaries, summed up sub-injection effect, at the same time on the causes of low-production wells were analyzed at the same time for different types of fine measures to adjust and measure the effect of analysis to improve single-well output and improve water absorption , A certain rise in water control, improve development effectiveness.
