Contradiction or when cannot achieve, it will be understood that the combination of this technical solution is not present, also not the present invention claims protection scope
Within.
The embodiment of the invention provides a kind of Reservoir Parameter Models construction methods of advantage seepage flow section for identification, referring to figure
1, this method comprises:
101, it according to natural gamma ray logging value, obtains nature gamma-phase and the shale of reservoir is obtained in conjunction with formation capacity to value
Content；According to interval transit time value, porosity is obtained；According to lithology factor, formation water resistivity, formation resistivity and the hole

102, the shale content of the reservoir, porosity, water saturation, rock permeability and pore throat radius, common structure
At the Reservoir Parameter Models.
Wherein, the rock permeability is fixed constant for any one rock.
On the basis of the above embodiments, the reservoir parameter of the seepage flow section of advantage for identification provided in the embodiment of the present invention
Model building method, it is described according to natural gamma ray logging value, it obtains nature gamma-phase and reservoir is obtained in conjunction with formation capacity to value
Shale content, comprising:
Wherein, V' is natural gamma relative value；GR is natural gamma ray logging value；GRminFor natural gamma minimum value；GRmax
For natural gamma maximum value；VshFor the shale content of reservoir；C is formation capacity.For old stratum, c=2, the Tertiary Period
Layer c=3.7 still takes c=3.7, finds out accurate V even if research area belongs to Cretaceous period argillaceous sandstone stratumsh.Shale content
VshIt is an important formation parameter, especially when evaluating muddy ore.Shale content, which can not only be sent out, reflects lithology,
It can reflect many situations on stratum, such as effecive porosity, permeability, water saturation parameter.If stratum contains shale, or
It is more or it is few overwhelming majority well logging can all be had an impact, when evaluating many situations of reservoir, will use shale content this
A parameter.It is difficult only accurately to evaluate stratum shale content using a kind of logging method during comprehensive log interpretation, this is
Because of many different factor collective effects of shale content.
On the basis of the above embodiments, the reservoir parameter of the seepage flow section of advantage for identification provided in the embodiment of the present invention

Layer explains that standing in the breach for task is exactly accurately to determine the parameter.Our warps of porosity calculation are close frequently with interval transit time, lithology
One or several combination in degree, compensated neutron log curve.But due to only studying block in the case where acoustic logging
Therefore porosity logging method can only establish the empirical relation formula of core analysis porosity and interval transit time and density data.
The porosity of reservoir is sought with this.
On the basis of the above embodiments, the reservoir parameter of the seepage flow section of advantage for identification provided in the embodiment of the present invention

Formation resistivity；M is rock cementation factor.The determination of water saturation is the another item background task for evaluating reservoir.Many moneys
Material all can provide relevant information to reservoir saturation degree, but from the point of view of current research real current situation, it is most popular to be
Saturation degree is evaluated with rock-electric test and resistivity.For clean sandstone water layer, when changing porosity, 100%
Aqueous sandstone resistivity RoWith formation water resistivity RwRatio Ro/RwFor a constant, F is known as formation factor, it and porosity close
System indicates are as follows:
SwCalculating be to pass through R firsttWith pure water layer R under the conditions of identical porosityoRatio I, it be referred to as resistance increase
Rate, then I=b/Sn W, then can useIt is calculated.
On the basis of the above embodiments, the reservoir parameter of the seepage flow section of advantage for identification provided in the embodiment of the present invention
Model building method, it is described according to mercury saturation degree, pore radius is obtained in conjunction with rock permeability and obtains pore throat radius, is wrapped
It includes: if the mercury saturation degree reaches 50%, obtaining corresponding pore radius；The pore radius, with the rock permeability
Rate is directly proportional, and the rock permeability is directly proportional to the pore throat radius.Rock permeability is the object of describing reservoir Penetration Signature
Parameter is managed, many problems of reservoir are had important practical significance.In general, reservoir has connectivity hole, such as hole
Gap, solution cavity, capillary and crack etc. are that have infiltrative necessary condition.Permeability can measure under laboratory, and fluid is allowed to pass through
Standard rock sample measures its permeability.To under the fluid and rocky condition being independent of each other, the form of rock is not by the shadow of other factors
It rings, then the permeability and fluid properties that homogeneous fluid is measured are not related, only related to rock matrix characteristic.Therefore for one
Determining rock sample, its permeability are a constants.What common well-log information all can directly not be associated with permeability,
The Penetration Signature of reservoir is obtained using the fit correlation between permeability and porosity, median grain diameter indirectly under normal circumstances.
For the acquisition of pore throat radius, formation pore possesses sufficiently complex structure, and pore throat radius and its distribution also respectively have
Difference.General equivalent pore radius (Rer), pore constriction radius and pore radius intermediate value (R50) etc. be describe pore throat situation ginseng
Number.Equivalent pore radius is the parameter for describing pore character, assumes that hinder with practical rock sample with identical seepage flow under normal circumstances
The equivalent rock sample of power；The pore radius intermediate value that capillary pressure curve obtains is surveyed using pressure mercury, establishes accumulation mercury saturation degree and hole
Corresponding relationship between gap radius, the corresponding pore radius value when mercury saturation degree reaches 50%.Pore throat radius, rock seep
When reservoir is flooded, three shows to be positively correlated for saturating rate, pore radius.Relationship in relation to pore throat radius and rock permeability can
With referring to fig. 2.It include: maximum pore throat radius and permeability theory relation curve 201, maximum pore throat radius and permeability in Fig. 2
Actual relationship discrete value 202, average pore throat radius and permeability theory relation curve 203, average pore throat radius and permeability are real
Border relationship discrete value 204, pore throat radius intermediate value and permeability theory relation curve 205 and pore throat radius intermediate value and permeability are practical
Relationship discrete value 206.As seen from Figure 2, either theoretical value or discrete value, maximum pore throat radius, average pore throat radius and
Pore throat radius intermediate value, it is proportional with permeability.
