摘要
本文介绍了分形理论在储层构造裂缝评价中的应用,提出了计算分形维数的网格覆盖法。以沈阳油田边台潜山岩心为例,分析了应用分数维D值定量描述储层裂缝复杂程度的可行性和可信度。该方法可用于深入研究和预测储层构造裂缝,以提高低渗透及特殊储层油气采收率。
This paper presents the application of fractal theory to the evaluation of structural fractures in reservoirs and puts forward a grid-coverage method to calculate the fractal dimension. Taking the cores from bumed hills of Shenyang oil field as an example, the authors analyzed the feasibility and reliability of using the fractal dimension D value to quantitatively describe the complexity of reservoir fractures, which provides a practical and applicable method for quantitatively describing, predicting and further studying the structural fractures of reservoirs as well as enhancing the recovery factor of oil and gas in low permeability and unconventional reservoirs.
