On Well Pattern Modifications of a Bottom Water Reservoir in Tahe

塔河某区块强底水油藏在开发后期,面临油井含水高、上升快、油产量递减快等问题。为此采取井网调整措施来提高产量和采收率。首先计算井网的控制程度,采用数值模拟方法确定剩余油的分布,通过方案预测选择出最佳井网,为该区块油藏井网调整提供了依据。

A strong bottom water reservoir in the late period of development in Tahe faces the problems such as high water cut in oil wells, the rapid rising of water cut, the serious depletion of oil production and so on. So a series of measures are taken to enhance the oil production, and the well pattern modification is one of the key measures to improve the well production. In this article, the control degree of the well pattern is calculated and the residual oil distribution is determined by numerical simulation. At last, the optimal well pattern is found, which can set up a basis for the actual pattern modifications.
