摘　　要：针对牛心坨潜山油藏在直井注采开发方式下存在水窜严重、采收率低的问题,在储层分布研究基础上,开展储层分类综合评价,综合运用油藏工程、数值模拟等技术手段,确定利用水平井重新构建油藏注采系统的二次开发思路,纵向上分段部署水平井,实现油藏立体开发。目前先导试验取得较好效果,油井产量是周围直井的2.5倍,水平注水井吸水指数是直井的4.3倍。In view of the problems of quick water breakthrough,low recovery ratio by using vertical wells to develop in Niuxintuo buried hill reservoir,based on the evaluation of reservoir stratas,geology system is reconstructed.With the method of reservoir engineering and numerical simulation,water flooding system by horizontal wells is determined.Horizontal wells in different depth can achieve oil development in scope.At present 2 horizontal wells are implemented in the trial development.Oil production of horizontal wells is two and half times that of vertical wells.Injectivity coefficient of injecting horizontal well is as far as 4.3 that of vertical wells.The result is referenced by other buried hill reservoir.
