摘要
利用绥中36-1油田G区块油藏冷冻取心岩样,研究了疏松砂岩油藏在无应力和有应力条件下微细粒运移的特征。结果表明,疏松砂岩油藏冷冻取心岩样的流速敏感性评价实验结果不能反映油层岩石微细粒运移的真实特征。疏松砂岩油藏开采过程中,油层压力下降和采油速度的增加以及岩石结构的破坏,是造成油层岩石微细粒运移和油井出砂的主要原因。
Micro fine migration in unconsolidated sandstone reservoir under conditions of stress and stress-free is studied by using cold coring samples from such reservoirs in Block G of Suizhong36-1 Oilfield.The result indicates that the flow velocity sensitivity of these samples can not reflect the real feature of micro fine migration.Reservoir pressure decline,the increase of recovery rate and the damage of rock structure are main reasons of micro fine migration and sand production during oil recovery process of such reservoirs.
