| Abstract: | A stationary mathematical model describing the time-integrated effect on an oil-saturated reservoir during drilling is considered. Calculated results are compared with the solution of the problem in an exact nonstationary formulation. The formation of an invaded zone in straight borehole drilling in water-and oil-saturated reservoirs is studied by numerical modeling. __________ Translated from Prikladnaya Mekhanika i Tekhnicheskaya Fizika, Vol. 49, No. 2, pp. 113–122, March–April, 2008. |
