Loose sandstone and long-term water flooding oil wells will cause a large amount of sand production in oil wells. In order to prevent sand production, on the one hand, correctly choose cementing and completion methods according to oil layer and oil well conditions, then make reasonable production measures and control production pressure difference; On the other hand, according to the requirements of the oil layer and the production process, the corresponding sand control technology is adopted to ensure the normal production of the oil well.
