疏松砂岩储层出砂机理和保护措施——以太平油田和尚店油田为例

Mechanism and protective measures of sand production in loose sandstone reservoirs-taking Taiping and Shangdian oilfield as examples

从岩石微观结构出发,以疏松砂岩储层的生产实践为基础,分析了出砂机理,对钻井到试采阶段引起油层出砂的因素进行了探讨;列举了各类入井液在疏松砂岩储层中引起的伤害类型;提出了不同类型出砂储层的保护措施。

Based on analysis of rock microstructure and the production practice of loose sandstone reservoir, sand production mechanism is analyzed, and the factors on sand production of oilbearing formations from the drilling to the productivity test period are discussed. The types of damage caused by each type of injected fluid in loose sandstone reservoir are listed. Protective measures for different types of sand production formations are suggested.
