摘要: 川中大安寨油藏为典型的低孔、低渗复杂裂缝性油藏,具有严重的非均质性,其独特的地质与开发特征,使常规的油藏工程方法难以开展或不能取得满意的效果。裂缝系统地质储量的早期预测一直是急待解决的问题。为此,提出了油藏影响函数法,建立了通用影响函数模型,并采用线性规划法求解其数值解。利用该方法可快速、准确地预测裂缝系统弹性容量、地质储量等,为滚动勘探开发提供了决策技术依据,为深化裂缝系统的油藏工程研究提供了新的途径。

Abstract: Da-An-Zai reservoir is a typical oil reservoir with low porosity, low permeability and serious heterogeneity, it has unique characteristic of geology and exploitation. So the conventional method of reservoir engineering can not be used or satisfactory results gained. But the calculation of reserve in fracture
system is an urgent task all alone. This paper presents a method of reservoir influence function, a model of general RIF is developed, linear programming approach used to solve it numerically.The elastic volume capacity and reserve of fracture system etc.Using the IRF method are calculated. This approach can provide decisive and technological basis for progressive exploration and development, and give new way for the deepening research of reservoir engineering for fracture system.

Key words: fracture reservoir, geologic reserve, prediction, mathematical model, influence function
