Oil-soluble DRA Development and Application
To solve the single tube gathering process paraffin oil viscosity reduction shaft and gathering the problem of high back pressure.Technical application of crude oil pour point depressant,mixed ester,benzene,ethylene oxide such as octylphenol ether compound by an oil-soluble DRA.Dosage in the 50~100mg/l to meet the water when the wellbore is less than 25% of the wax viscosity and single-tube process requirements gathering,can be compared to the multi-port wells,monitoring data before and after dosing showed that the crude oil after dosing freezing point decreased 5.6 ℃,the average rate of 87.4% viscosity reduction,the average rate of 91.5% paraffin.Pipeline wellhead back pressure reduced by 20 to 30 percentage points.
