The improvement of condensate properties by two methods

chemical dosing and oil dilution was investigated. The results show that BASF coagulant has the best coagulation reduction effect when chemically dosed

with the coagulation reduction range up to 12℃

and the best dosing amount is about 90ppm; the oil phase of liquid hydrocarbon separator can reduce the coagulation point of highly coagulated and viscous condensate to 0℃ with the dosing ratio of 20% in the blending experiment

and the reduction range reaches 100%. The comprehensive comparison suggests that oil dilution can synergistically solve the changes caused by condensate production reduction

and is more suitable for solving the problems caused by the deterioration of condensate physical parameters.
