Key words: reservoir, effective pressure, deformations, core sample, the development of deposits.

According to the results of analysis of main geodynamic parameters (rock, breakdown, formation pressures, oil and fluid production rates) were calculated the compensation factors of rock pressure, deformation loss, productive capacity for over 23 oil fields, 29 accumulations and more than 600 oil wells in Rechitsko-Vishanskaya area of Pripyat foredeep. The classification of accumulations by stress - strain state was developed for the whole period of well operation. Constant monitoring of changes in stress - strain state of complex structure reservoirs during drilling process, testing, deployment, developing and production of oil will allow us to manage these processes in a timely manner and increase oil recovery.
