oilfield is a typical layered reservoir with a large vertical span and many
oil-bearing formations. There are significant differences in reservoir types
and fluid properties among various formations. The interlayer interference is
severe in the development process. At present, the interlayer interference
research based on dynamic monitoring data cannot meet development adjustment
needs. Combined with the field test results, through the indoor physical
simulation experiment method, dynamic inversion method, and reservoir
engineering method, this paper analyzes the main control factors and
interference mechanism of interlayer interference, studies the variation law of
interference coefficient, improves and forms the quantitative characteristic
Theory of interlayer interference in multi-layer commingled production, and
provides theoretical guidance for the total adjustment of the middle strata
division in the oilfield.
