Paraffin Removal technology；The disadvantages of the method are as follows technique input cost is high, flow chart is many and diverse, and power consumption is high.
Chemical Paraffin Removal, dominant mechanism are divided into two kinds, and one kind improving temperature, melted paraffin by chemical reaction；It is another
It is that paraffin is directly dissolved by chemical substance.The disadvantage is that being easy to produce poisonous and harmful substance, related personnel's health is influenced.
Microorganism Wax Removal And Paraffin Inhibition is that relevant microbial bacterial is injected into pit shaft, passes through the metabolism of microorganism
Function prevents wax crystal, is mainly used for wax control, but the condition different for different salinities and different temperatures and oil property
Under it is less for preferred microorganism, and be only limitted to wax control, wax removal effect be not obvious.
A kind of efficient, energy-saving and environmental protection Paraffin Removal device is studied, thus to meet current low cost exploitation needs and energy conservation
Demand is very necessary.
