Abstract

The invention provides an oil reservoir numerical simulation method and apparatus based on high water-cut period monitoring data constraints. The oil reservoir numerical simulation method includes acquiring the data of a production well, an injection well and an oil reservoir, and determining the dynamic parameters and static parameters of the wells and the oil reservoir; generating water logging three dimensional characteristics at different time based on the logging interpretation data in the static parameters; generating the residual oil distribution rules at different time based on the inspection well coring data in the dynamic parameters; establishing a geological model based on the static parameters of the oil reservoir, and initializing the geological model based on the original formation pressure distribution or the relation of pressure and depth, and rock and fluid properties; historically matching the initialized geological model to generate a history matching result; and historically matching the oil reservoir numerical simulation based on the water logging three dimensional characteristics, the residual oil distribution rules, and the history matching result. The oil reservoir with different water logging and residual oil distribution characteristics at the high water-cut stage is numerically simulated in high precision.

Description

technical field [0001] The invention relates to oil reservoir numerical simulation technology, in particular to an oil reservoir numerical simulation method and device based on monitoring data constraints in high water-cut periods. Background technique [0002] After decades of development, most oilfields in my country have successively entered high water-cut and ultra-high water-cut periods. According to the data statistics of water cut and recoverable reserves recovery degree of each oilfield, except Changqing Oilfield whose water cut is lower than 60%, the other oilfields are all above 70%, and are in the development period of high water cut and ultra-high water cut. Excavating the development potential of old oilfields is an arduous task for petroleum workers, and the distribution of remaining oil is very complicated. Reservoir numerical simulation is the most scientific and practical technical means to find the distribution of remaining oil. In the past ten years, with...
