摘要
通过对油页岩热物理性质和电物理性质的分析,构建了一个三维数值模型进行油页岩的演化模拟。根据数值模拟模型得到的结果,对油页岩在高压环境下的热重曲线、导数热重曲线、饱和水相相对渗透率、饱和油相相对渗透率等性质进行了分析。结果表明,高压环境下,油页岩的电阻率通常比常压环境更低,此外分析结果还得出,饱和水相相对渗透率与含水饱和度、含水饱和度均呈现负相关,而饱和油相相对渗透率与含水饱和度和饱和气油相相对渗透率与液相饱和度均呈现正相关。高压环境是油页岩储层中的常见条件,研究高压下油页岩的物理性质可以更好地理解储层中的孔隙结构、渗透性、孔隙度等特性。这对于确定储层贮藏能力、预测产量和优化开采方案具有重要意义。
A three-dimensional numerical model was constructed to simulate the evolution of oil shale by analyzing the thermal and electrical properties of oil shale.Based on the results obtained from the numerical simulation model,the thermal gravimetric curve,derivative thermal gravimetric curve,saturated water phase relative permeability,saturated oil phase relative permeability and other properties of oil shale under high-pressure environment were analyzed.The results indicate that in high-pressure environments,the resistivity of oil shale is usually lower than that in atmospheric pressure environments.In addition,the analysis results also show that the relative permeability of saturated water phase is negatively correlated with water saturation and water saturation,while the relative permeability of saturated oil phase is positively correlated with water saturation and saturated gas oil phase is positively correlated with liquid saturation.High pressure environment is a common condition in oil shale reservoirs.Studying the physical properties of oil shale under high pressure can better understand the pore structure,permeability,porosity and other characteristics in the reservoir.This is of great significance for determining reservoir storage capacity,predicting production,and optimizing mining plans.
