STUDY ON THE MODEL OF CONTAMINANT IONS REACTION AND DIFFUSION NEAR WELLBORE

ABSTRACT
During the development of oil field, well operation fluids will inevitably invade the formation, and insoluble is produced when contaminant ions contained in operation fluids react with formation fluids, which will easily plugs the pores, consequently affecting the flow of formation fluids. It is of remarkable significance for formation damage evaluation to study the laws of contaminant ions transportation and distribution near wellbore. In this study, the characteristics of highspeed percolation and contaminant ions diffusion near wellbore are reasonably considered, and then we established the non-Darcy flow reaction-diffusion equations, from which the contaminant ions distribution and transportation will be illustrated, thereby, the effects of pollutants migration and reaction on porosity and permeability are further studied. Thus, the newly developed model can provide theoretical basis and practical reference for plug removal.
