在研究油井出砂机理的基础上,根据液-固多相渗流条件,应用库仑-摩尔破坏准则和达西公式,导出了关于疏松砂岩油藏不同产液量下油井出砂量预测的数学模型.以盘二油田为例,进行了出砂预测,与实测含砂比相比,平均误差小于0.0052%.实例应用表明所给的数学模型是可行的. |

On the basis of studying the mechanism of sand production, a mathematic model is derived for predicting the well sand production under different liquid producing capacities in unconsolidated sandstone reservoirs, by using Cou-lomb-Mohr failure criterion and Darcy's law according to the theory of multiphase liquid-solid filtration. The sand production is predicted by taking Pan 2 Oilfield for example. The result is correlated with measured sand production ratio with average error less than 0. 0052%. The application of example shows that the mathematic model is feasible. |
