Paraffin Technology Research And Its Application In Yanchang Oilfield

The view of the present status of the extension of the oil field oil well paraffin deposit in this project, by using the combined method of chemistry and physics paraffin, to solve the problem of the extension of the oil field oil well paraffin deposit. Select the appropriate chemicals, determine the amount and efficient cavitation magnetic coupling paraffin, paraffin removal agent of dissolving speed, amount of soluble wax, wax dosage and efficient sound cavitation magnetic coupling wax prevention measures after the wax as the main evaluation index such as time, in order to realize the safe, non-toxic, efficient paraffin purpose, the method has good application prospect.Through the objective of the research, according to the characteristics of extended sense oilfield crude oil chemical paraffin remover and efficient sound cavitation magnetic coupling paraffin research and main achievements of the following aspects:1.through the five production sample(each plant 20) crude oil components, infrared spectra analysis, microstructure analysis, carbon number distribution of wax and crude oil rheology and viscosity-temperature relationship test analysis: extend the oilfield waxy crude oil between 10% and 16%, related points lower, between 21 and 26 ℃;2.through the five wax precipitation of prevention and control of production and technology research, developed a composite paraffin removal agent, has the high dissolving rate and amount of soluble wax, wax can effectively prevent the precipitation of wax, paraffin rate can reach 60%;3.developed a new type of cavitation acoustic magnetic coupling paraffin, can effectively prevent the precipitation of wax.Since the implementation of the project in the field can be suitable for the extension of the oil field different wellbore conditions, waxy crude oil and paraffin construction requirements of oil well paraffin of form a complete set technology.
