摘要
从岩石力学原理出发,结合稠油出砂冷采过程中的动态特征,研究了等温条件下疏松砂岩体积应变率随累积产油量和累积出砂量的变化规律,建立了出砂冷采过程中储层孔隙度的预测模型。该模型可以定量预测稠油出砂冷采过程中储层孔隙度的变化规律,从而为出砂冷采过程中其他规律的研究奠定了基础。
Based on rock mechanical principles and the performance of heavy-oil cold production, the change of volume change rate of the unconsolidated sand has been studied along with cumulative oil production and cumulative sand production under isothermal condition. A porosity prediction model is built to quantitatively predict the average porosity change of the unconsolidated reservoirs during cold production. It laid the foundation for the study of other trends during the cold production.
