| 摘 要： | 年增可采储量是评价油气田开发效果的重要参数。由于油气田特性在开发过程中是动态变化的,给可采储量预测带来了一定难度。文中提出采用轮廓线拟合和切线相结合的方法(即平滑切线法)预测年增可采储量,是对现有预测模型在应用方法上的一种创新,该方法适合于大型油气田中期以及中小油气田后期的开发评价,具有较高的预测精度。

| Abstract: | Annual increment of recoverable reserves is an important parameter in evaluation of oil and gas fields development result.The change of reservoir property during development process brings certain difficulty to estimation of recoverable reserves.This paper proposes using the combination of contour line fitting with tangent line(i.e.smooth tangent) to estimate annual increment of recoverable reserves.This method is an innovation in application of existing forecast model,can be applied to development evaluati... |
