The Application Of Modifier On Pumping Wells

Design and development of a new anti-wax Dosing systems, applications of crude oil flow improver, to extend the wash cycle heat pumping wells. Will flow improver to a relatively stable dose of inhaled plus mouth to pump in order to ensure the realization of a stable increase in drug concentration in order to achieve "one in the end, non-hot wash, non-heating" and wax-free clearance of the double room temperature transmission purpose.By maintaining effective concentrations of anti-wax method Dosing studies to determine the appropriate increase in drug concentration to ensure the increase in drug effect.Canadian drug pipeline through the Water and antifreeze process to ensure that drug technology scene plus the feasibility and practicality, and the winter cold in Daqing circumstances to ensure normal production and the purpose of saving energy and reducing consumption.Wellhead flow through the drip ring Dosing technology research, so that annular flow can be well Dosing normal to ensure that the process will not be a special problem because the process can not be normal Dosing.Through the emulsion to be pumped into the relationship between flow resistance studies to determine the reasonable rate of drug concentration, so that the rate of drug in the pump barrel of crude oil greatly reduced the resistance, underground pump more liquid into the well, an increase of the pump is full of coefficients to improve the pump efficiency .Tests conducted on-site presentations, and adopted after a string operation, the increase in drugs before and after the oil wells to the production of petrol filling stations are compared to determine the effect of the study.Three years, 220 wells on-site tests showed that local production wells (including pumps, screw) technology-free paraffin oil flow to be relatively stable modifier to increase the dose of inhaled mouth to pump to the oil-free ground clearance and low-temperature wax the dual role of gathering and transportation, to achieve the production and saving energy and reducing consumption.
