目前，在俄罗斯开发新油区时发现高含蜡油田的机会越来越多。石蜡通常以液态存在于石油中、在油藏开发过程中一旦改变地层的温压条件，它就以固态析出。地层石油的相态变化对石油在地层和近井底带的渗流肯有负面影响。石油在油井套管中运移时，析出的固态石蜡在管壁和泵装置上沉淀下来。这些因素导致了原油产量的下降. At present, there are more and more opportunities for discovering high waxy oil fields in the development of new oil fields in Russia. Paraffin wax is usually present in oil in the liquid state. Once the temperature and pressure conditions of the formation are changed during the development of the reservoir, paraffin is precipitated in a solid state. The phase change of the stratum oil has a negative impact on the oil seepage in the strata and the near-wellbore. As the oil migrates through the well casing, the precipitated solid paraffin deposits on the pipe wall and in the pump unit. These factors led to the decline in crude oil production.
