Device.
Background technique
Reservoir heterogeneity refers to the inhomogeneity inside reservoir, is mainly shown as the side such as reservoir lithology, physical property, oiliness
The anisotropy in face, it is the main reason for influencing remaining oil distribution；According to the longitudinal microcosmic Petrographic Features variation of reservoir
Rule is divided into positive rhythm, the anti-rhythm and compound rhythm reservoir.
Positive rhythm reservoir is the common trait of various fluvial deposit sand bodies, from the coarse to fine from sandstone bottom to top granularity,
Permeability is lower by height；Due to the difference of river deposition, the permeability grade of many Fining upwards sands changes very greatly, thus
The difference for leading to oil saturation is a kind of highly undesirable oil reservoir；Anti- rhythm oil reservoir reflection depositional environment hydrodynamic condition by
It is weak that strong rule variation, highest permeable formation is at the top of sand body, and lithology, physical property are gradually deteriorated from top to bottom, density is gradually increased,
Apparent resistivity reduces, and due to the difference of deposition, the permeability grade of many coarsening upwards sands changes very greatly, so as to cause containing
The difference of oily saturation degree is also a kind of highly undesirable oil reservoir；Compound rhythm oil reservoir is positive and negative two kinds of cadence types
Combination, internal lithology, physical property, electrical property feature and rule of waterflooding are controlled by top and the bottom cadence type respectively, in oil-field flooding
It in development process, shows as that middle part is advanced by leaps and bounds or more uniform waterline promotes type, is mostly middle and high water logging in the middle part of the rhythm；In the rhythm
Top and bottom are low, non-water logging.
Exploitation experiment is the basis of oil-gas field development, can not only be calculated for the reserves of oil-gas reservoir, development plan establishment, oil
The work such as hiding numerical simulation provide basic oil deposit parameter, additionally it is possible to solve the problems, such as many providers encountered in oil reservoir development
