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储集层渗透率随产油量与产砂量的变化规律,建立了出砂冷采过程中储集层渗透率预测模型。该模型可以定量预测出砂冷采过程中储集层平均渗透率变化规律,从而为出砂冷采过程中产量变化规律研究奠定了基础。

Abstract: Based on rock mechanical principles, integrated with the performance of heavy-oil cold production, the permeability changes of unconsolidated sandstone reservoirs with oil production rate and sand production rate are studied under the isothermal conditions. The quantitative permeability prediction model is developed for the heavy-oil cold production. This provides a basis for study of variation of oil production rate during cold production with sand control.

Key words: heavy oil reservoir, sand control, cold production, permeability, prediction
