Effect evaluation of positive ion amoebae particle profile control agent after polymer flooded reservoir

The results show that the programming with C51in VPPAW controlling system has better readability,structure and realization of algorithm than with assembler language,and can fully meet the needs of equipment system.

According to the trend of VPPAW equipment, a design scheme is introduced in which the welding machine is supplemented with double power sources, the main circuit being a inverter and the control system adopts singlechip technology instead of traditional analog technology.
