Abstract: A vapor blow through avoidance method, process and system for oil producing wells developed based on an innovative theory of vapor blow through pump. The system consists of casing gas remover, dynamic fluid level detector and downhole pump. Process includes adjusting casing gas remover and or pump rate based on result of comparison of the detected dynamic fluid level with the pre-set target dynamic fluid level; therefore, it prevents vapor in annular space blowing through pump and optimizes the well production. The avoidance system applies to single or group and horizontal or vertical wells.
