Mathematical modeling of processes in the near-wellbore zone during thermo-chemical gas impact

Authors: A.N. Ivanov, M.A. Fedoseev, E.N. Grishenko (Research and Engineering Institute, Vietsovpetro JV, the Socialist Republic Vietnam, Vung Tau), E.M. Koltsova (D. Mendeleev University of Chemical Technology of Russia, RF, Moscow)

Key words: thermo-chemical gas impact, mathematical modeling, dynamic compositional modeling, methods of oil production intensification

Methods of oil production intensification are considered. On the example of low-rate well of Lower Miocene of White Tiger oilfield an analysis of the results of numerical modeling carried out for the selection of the optimum parameters for safe and efficient termo-chemical gas impact on bottomhole zone using solid fuel charge based on ammonium perchlorate, a rationale for the choice of optimal charge provided. The method of study of optimal parameters for thermo-chemical gas impact on bottomhole zone is shown; recommendations for real well are given.
