Why precision is low in view of existing reservoir numerical simulation for inventor, is primarily due to carrying out numerical reservoir mould
The when of plan, do not take into full account, at different times, the oil reservoir of areal is carried out the Flooding Characteristics acquired in drilling well, oil reservoir
The rising rule of oil-water interfaces and the distribution characteristics of remaining oil.Meanwhile, along with oil field development enters high water cut rate, owing to injecting
Washing away for a long time of water, oil reservoir easily forms macropore, and oil-water seepage produces considerable influence, but, existing numerical simulation
Method does not consider the macropore impact on oil reservoir, thus causes reservoir numerical simulation precision relatively low.
Based on this, inventor is in view of during carrying out reservoir numerical simulation, it is possible to use above-mentioned various features is joined
Count and combine the method that the static nature parameter of drilling well carries out reservoir numerical simulation jointly.Specifically, in embodiments of the present invention,
Propose a kind of numerical reservoir and determine method and apparatus, as it is shown in figure 1, may comprise steps of:
Step 101: in acquisition work area, drilling well is in the static parameter of different times；

Well track, geological layering data, log analysis data, different times perforating parameter, drilling and coring delivery data and core observation data.
But actual realization when, it is also possible to according to practical situation and need to select other type of static parameter,
This is not construed as limiting by the application.
Step 102: set up the initial geological model of oil reservoir according to described static parameter；
Geologic modeling refers to entering geology, well logging, geophysical information and various explanation results or conceptual model
On the basis of the comprehensive analysis of row, utilize the 3-D quantitative stochastic model that computer graphics techniques generates.
The earthquake model of oil reservoir be the type of oil-gas reservoir, geometric shape, scale, oil reservoir internal structure, reservoir parameter and
The high level overview of fluid distrbution.It is the basis of reservoir comprehensive evaluation, is also simultaneously the important foundation of reservoir numerical simulation and opens

Beginning geological model.This is not construed as limiting by the application.
Step 103: described initial geological model is carried out history matching, obtains the initial history fitting result of oil reservoir；
In the present embodiment, the reliability of geological model can be improved by revising initial geological model obtained above,
Thus realize the history matching to geological model.
Step 104: oil reservoir is at the characteristic parameter of different times according in the described work area of described static parameter acquisition, wherein,
Described characteristic parameter includes at least one of: reservoir characteristic parameter, seepage flow characteristics parameter, Flooding Characteristics parameter, oil reservoir profit
Rule, remaining oil distribution characteristic parameter and macropore characteristic parameter is risen on interface；
In the present embodiment, after obtaining the static parameter of drilling well, oil reservoir can be obtained when difference according to following steps
The characteristic parameter of phase:
S4-1: according to the drilling and coring delivery data in static parameter, determine oil reservoir in the reservoir characteristic parameter of different times and
Seepage flow characteristics parameter；
Generally, in the reservoir characteristic parameter of different times, oil reservoir may include that porosity, permeability, reservoir are non-
Homogeneity etc.；Oil reservoir may include that relative permeability, capillary pressure curve, displacement of reservoir oil effect in the seepage flow characteristics parameter of different times
Rate, wettability etc..
Oil reservoir characteristic parameter and the seepage flow characteristics parameter of different times are the most different.In the present embodiment, with somewhere
Oil reservoir illustrates as a example by different times porosity and permeability, and certainly, the present embodiment is intended merely to the application is better described,
It is not intended as the restriction to the application.
It is illustrated in figure 2 somewhere reservoir pore degree schematic diagram under different times difference water flooding degree, as shown in Figure 3
For somewhere Reservoir Permeability schematic diagram under different times difference water flooding degree.Oil reservoir different times water flooding degree not
With, in this example, oil reservoir is divided at the water flooding degree of different times: non-water logging, weak water logging, middle water logging and strong water logging this
Four kinds of situations, the porosity of oil reservoir corresponding from Fig. 2 and Fig. 3 it can be seen that in the case of these four respectively and infiltration
Rate is the most different.
S4-2: according to the core observation data in static parameter and log analysis data, determines that described oil reservoir is in difference
The Flooding Characteristics parameter in period, reservoir oil water termination rise rule, remaining oil distribution characteristic parameter and macropore characteristic parameter.
In the present embodiment, can be according to the core observation data in static parameter, log analysis data and according to shape
Become the geologic feature of macropore, analyze whether somewhere exists macropore.Such as: the display of tracer data injects water along certain side
To quickly advancing by leaps and bounds, then may form macropore at this；A certain layer Liquid output is found when measuring production profile or intake profile
Or water absorption is far longer than other layer of position, then it is likely to be formed macropore at this；Rock core in somewhere finds that a certain layer is the thinnest
Pine, reservoir properties is fine, and water logging is relatively strong, and this layer of position is washed the most weak up and down, then there may be macropore at this.Determining
After somewhere exists macropore, the macropore characteristic parameter in somewhere can be obtained, can include but not limited to following at least it
One: water (flow) direction in macropore distributing position, macropore, porosity, permeability, relative permeability and capillary pressure curve.

Unique method.Such as many conventional method oil reservoirs to be supposed are circular uniform dielectric, as the most more complex in oil reservoir geometry,
And be nonisotropic medium, then solve extremely difficult, even cannot solve.And for numerical simulation for oil-gas reservoir, calculate form multiple
Miscellaneous heterogeneous reservoir is almost the same with the Homogeneous Reservoir workload calculating simple shape.Therefore reservoir numerical simulation can solve
The certainly indeterminable problem of other method.The problem that can solve for other method, can faster, more with method for numerical simulation
Save, more convenient, solve more reliably, and increase other analyze method credibility.

Contrast with macropore characteristic parameter.If comparing result differs greatly, and the mathematical model used is accurate, then it may be said that
Static parameter used by bright history matching does not meets the practical situation of oil reservoir.At this point it is possible to according to static parameter and reservoir characteristic
Parameter, seepage flow characteristics parameter, Flooding Characteristics parameter, reservoir oil water termination rise rule, remaining oil distribution characteristic parameter and macropore
The relation of road characteristic parameter, makes corresponding amendment, then by amended static parameter again to the static parameter used
Secondary carrying out calculates and contrasts.If the most variant, the most again modify, until result of calculation is suitable with measured result
Close, reach the range of error allowed.Specifically, may comprise steps of:
S5-1: initial history fitting result and characteristic parameter are contrasted, obtains comparing result；
S5-2: numerical reservoir is adjusted according to comparing result, the numerical reservoir after being adjusted.
Owing to, during carrying out history matching, analog parameter quantity is the most, adjustable scope is the biggest, and actual
The kind of Reservoir Data and limited amount, be not enough to uniquely determine the model parameter of reservoir modeling.In order to avoid or reduce repair
Change the randomness of parameter, when geological model is carried out history matching, it may be determined that the adjustable extent of geological model parameter, thus
The adjustment that can ensure that analog parameter is in scope rational, acceptable.Generally can by collect and analyze all can
The adjustable extent of reservoir modeling parameter is determined with the data utilized.

± 25%；Oil-water interfaces combine different times drilling and coring delivery result of study and are adjusted, by result precision control, on its basis
Upper adjustable extent is ± 10%.
Also do not have a kind of general method currently for historical simulation, conventional way is repeatedly to revise parameter by experience
Carry out tentative calculation.After determining the parameter carrying out history matching, can according to the analog parameter of selected input geological model with
Carry out the significance level of the parameter of history matching, one of them or several parameter are adjusted, such that it is able to shorten
