A Computer Simulation System for Predicting the Effectiveness of Scale Inhibitor Injection in the Oil Fields

The fundamental theories of mass transfer and heat transfer were used and a computer simulation system was developed to predict the inorganic scaling tendency and the effectiveness of scale inhibitor injection in the oil field. The scaling tendency,the scale deposited profile from the bottom hole to the surface and the effectiveness of scale inhibitor injected can be easily predicted with the parameters of formation characteristics,the formation fluids,characteristics of scale inhibitor and construction conditions input into the system. And based on the predicted results,the economic evaluation can be made and construction plans will finally be optimized. The software is driven by a menu having good performances. It has a good interface between the computer and the operator. It is applicable to all common oil fields. its accuracy,reliability and practicality have been proven by comparison of the predicted results with the actually measured data.
