Features of fluid zoning in the multideposits field and determination of the mechanism of their occurrence (on the example of kremenivsky field)
Keywords:
field, deposits, fluid zoning, reservesAbstract
The author has made conclusions analyzing the literature on the mechanism of multideposits fields formation through vertical migration of tectonic disturbances and characteristics of fluid phase in state zoning of deposits on the example of the western arch of Kremenivsky field. It is assumed that the section of the western arch of petroleum accumulation process occurred within three cycles. It is suggested that on the cut of western arch the process of oil and gas accumulation occurred in three cycles. It is suggested that based on the ratio of the phases in the deposits from the top down in the sequence, the first cycle of oil and gas is the "oldest" - differentiation of bedded fluids took place in deposits; second cycle is intermediate - differentiation processes take place in it today; the third cycle is at the stage of deposits formation, i.e the "youngest". It is concluded that there probable exist gas condensate deposits in the Upper Devonian deposits with initial reserves of over 5 billion m3 of gas.
