Geology art personnel can obtain slightly obtaining to the reservoir average value such as average sand mud ratio, average pore of reservoir
To the carefully information such as the kv/kh to reservoir, anisotropic.These quantitative analyses can greatly improve our understanding to reservoir.So
It is not comprehensive enough and the country's equal data of Geological Modeling of the prior art are simple, mode is single, it is difficult to be drilled well construction
And later stage exploitation provides enough supports.
The content of the invention
For above-mentioned deficiency of the prior art, the present invention proposes a kind of reservoir three-dimensional geological modeling method, realizes complete
Face, reservoir three-dimensional geological model accurately is established, reach the purpose for being easy to be probed into detail reservoir basic geological information.
The present invention is achieved through the following technical solutions：
A kind of reservoir three-dimensional geological modeling method, in a certain exploration and development block, foundation geological conditions and goal in research demand,
Implement following technical step：（a）Implement 3-d seismic exploration in earth's surface；（b）Choose position at the N with symbolical meaningses, design
Prospect pit casing programme, carry out the construction operation of N mouth prospect pits；Wherein, following technical steps are implemented to every mouthful of prospect pit（Wherein N is
Positive integer more than or equal to 5）；（c）Full well section sieve residue log work 2m drags for sand once, it is contemplated that Reservoir Section 1m drags for sand once；（d）Entirely
Well section carry out resistivity logging, acoustic logging, nutural potential logging, gamma ray log, compensated neutron log, density log,
Calliper log, the above-mentioned log of the full well section of target well is obtained, makes well log interpretation；（e）Full well section carries out imaging logging, makees

Crosshole seismic；（h）With reference to drilling engineering data and above-mentioned well log interpretation, all reservoirs are listed, and to listed all storages
Layer carries out sidewall coring, and electron-microscope scanning observation, porosity determination, rock strain experiment are carried out to all rock cores of taking-up；（i）It is comprehensive
Above-mentioned well logging and the experimental data of N mouth prospect pits are closed, using modeling software, establishes reservoir three-dimensional geological model.
It is not comprehensive enough for the equal data of Geological Modeling in the prior art are simple, mode is single, it is difficult to be applied to be drilled well
Work and later stage exploitation provide the problem of supporting enough, and the present invention proposes a kind of reservoir three-dimensional geological modeling method.In this method,
Implement earth's surface 3-d seismic exploration first in a certain exploration acreage, determine stratigraphic structure, find out favourable hydrocarbon trap, provide herein
Being selected on material has position at the N of symbolical meaningses to carry out prospect pit construction, and wherein N is the positive integer more than or equal to 5, i.e., selected has
The prospect pit well location of symbolical meaningses comprises at least each a bite well in four orientation of trap, and a bite well of trap high point.In prospect pit
In work progress, full well section sieve residue log work 2m drags for sand once, it is contemplated that Reservoir Section 1m drags for sand once, and sand is dragged for using highdensity
Pattern, to improve the precision of sieve residue log as far as possible, geological personnel is set to have understanding substantially to formation lithology.Afterwards, implement conventional
Well logging, logging mode use cable or LWD tool, and well logging project includes but is not limited to resistivity, sound wave, nature
Current potential, natural gamma, compensated neutron, density, hole diameter, the above-mentioned log of full well section is obtained, makes complete well log interpretation,
Oozed with obtaining the detailed earth bore of the well, the information such as fluid, lithology.Imaging logging is carried out to full well section again.As identification crack
Effective logging mode most directly perceived, individually carry out an imaging logging operation and be necessary, because Image Logging Data
Can protrude because crack change caused by the variation characteristic of rock acoustic impedance and resistivity, reduce by drilling engineering etc. it is artificial because
Non- crack response influences caused by element, so as to correct conventional logging technology existing deficiency in terms of crack is analyzed so that ability
Field technique personnel can also have overall understanding to the crack information in the well stratum.Afterwards, focus is arranged at shaft bottom, carried out
VSP logs well, and makes well log interpretation.VSP logs well, i.e. vertical seismic profile log, is sentenced by the reflectance signature difference of seismic wave
Lift height situation between layer, the developmental state in crack, and each series of strata absolutely, in combination with every Logging Curves, from
And confirm well stratum interrupting layer, gap and the geological layer concrete condition.VSP well loggings can also be on the basis of imaging logging
On, the degree of fracture development is drawn by the strong and weak feature of back wave, researcher is had the development degree of formation fracture
Quantitative understanding.In addition, carry out crosshole seismic between N mouth prospect pits, crosshole seismic can receive abundant wave field information, between well
The dominant frequency of seismic signal is typically the several times even more high of surface seismic, and its imaging result can clearly disclose the ground between two wells
Matter structure, linking ground seismic data interpretation and brill, the effect of interpretation of logging data can be functioned well as, establish and store up in time-space domain
The relation of layer point, face and body, for fine reservoir description generation model.Afterwards, by above-mentioned all well-log informations, in conjunction with brill
The data such as geological logging, drilling parameter change during well, all reservoirs are listed, and well is carried out to listed all reservoirs
Wall is cored, and carries out electron-microscope scanning observation, porosity determination, rock strain experiment to all rock cores of taking-up, rock core is obtained with this
The significant datas such as high-definition picture, porosity and connectivity data, stress-strain diagram.All numbers according to above-mentioned N mouths prospect pit
According to establishing reservoir three-dimensional geological model using modeling software.
Above-mentioned steps are applied to selected all prospect pits, obtain the individual well geologic section model of every mouthful of well, further according to
Early stage delineation research to the oil-gas reservoir, using modeling software, can obtain shale gas reservoir three-dimensional geological model, be achieved in complete
Face, shale gas reservoir three-dimensional geological model accurately is established, reach the mesh for being easy to be probed into detail stratum basic geological information
's.
Further, step（b）Described in imaging logging be micro-resisitivity image（FMI or EMI）.
Further, the step（f）And step（g）It is sequentially adjustable.
The present invention compared with prior art, has the following advantages and advantages：
A kind of reservoir three-dimensional geological modeling method of the present invention, by implementing 3-d seismic exploration in earth's surface, select same block
The interior N mouth prospect pits with symbolical meaningses, intensive sand, conventional logging, imaging logging, the VSP of dragging for is carried out every mouthful of prospect pit and is logged well, well
Earthquake, complete and comprehensive well log interpretation is made, then the reservoir by being drawn to well log interpretation carries out sidewall coring, to institute's coring
