高含水后期双河油田开发地质工作方向

双河油田已全面进入高含水后期开发,急需明确高含水后期开发地质工作内容和方向。回顾了双河油田开发地质工作历程,指出了开发地质工作必须紧密围绕认识开采对象而展开。总结了高含水后期双河油田开采的剩余潜力特征,从而提出了细分薄单层,在成片水淹区内找出众多含剩余油小片;加强基础研究,深化剩余油三维特征认识;推动精细油藏描述的计算机化进程,尽快投放矿场应用;积极探索剩余油挖潜方法,提高老油田水驱采收率的开发地质工作方向。只有按油田生产的规律开展各项基础工作,才能保持老油田生产能力。

Direction of geologic study in late stage of development with high water cut in Shuanghe oilfield

Shuanghe oilfield has been in late stage of development with high water cut, therefore, it is highly urgent to determine the direction of geological study. This paper reviews the history of study of development geology, points out that development geological study must focuses on the producing targets, and summarizes the distribution characteristics of the remaining oil. The following geologic studies should be carried out in the future:identifying small layers with remaining oil in watered out region through fine division of thin single layers; understanding the 3D characteristics of the remaining oil through strengthening fundamental research; speeding up computerization of fine reservoir characterization and putting them into field application as soon as possible; activelystudying on ways to tap the remaining production potentials to enhance waterflooding recovery factor of the mature oilfield. The production capacity of mature oilfields can be maintained only when all the fundamental works are to be carried out according to the law of oilfield production.
