Flow Performance Test and Evaluation Method for ZZS Sand Control Screen
Conventional sand control methods are easy to encounter sand plug by reservoir sand under complex production conditions, thereby significantly reducing its flow performance. For this reason, a fold-type(ZZS)sand control screen is developed.
