Description
Technical field
The present invention relates to kind of a method for drafting for oil reservoir middle small layer tomography, belong to oil exploration technology field.
Background technology
Develop during synthetic geology research and meticulous pool description, to (or the microscopic structure of substratum sand body top surface structural map
Figure) making is more demanding, and the situation demands that oil field is deeply taped the latent power.This requires vast geology researcher in real work
In, drawing the corresponding geological map related with substratum must carry out using substratum structural map as base map.And tomography is substratum construction
The parent map element of figure.In practice, structure interpretation can not possibly be provided often by relative configurations interpretation software index bed tracer technique
The structural map of a substratum and the plane fault line based on substratum.Common version index bed is generally very few, probably there is 2-5,
And a set of oil-bearing series substratum number can reach more than 100.
So being derived based on known structure interpretation tomography layer position, unknown substratum position of fault is of crucial importance, and oil field is opened at present
Send out in geological research industry, draw the tomography of purpose substratum (middle substratum) by contrasting bedding fault up and down by hand more, not only
It is time-consuming and not accurate enough.
The content of the invention
In view of the above defects of the prior art, the present invention provides a kind of drafting side of oil reservoir middle small layer tomography
Method, can effectively draw the tomography of purpose substratum (middle substratum), improve the derivation precision of tomography drafting.
The present invention is achieved by the following technical solution：A kind of method for drafting of oil reservoir middle small layer tomography, specific step
It is rapid as follows：
Step 1：The digitlization of known plane fault line；
Step 2：Known digitized fault line is numbered, and marks tomography upper lower burrs fault line type；
Step 3：Upper stratigraphic horizon spatial data between tomography, lower tomography and unknown tomography known to calculating；
Step 4：Unknown layer data is derived, by software programming, derives unknown layer data in batches.Derive
Tomography is digitized for being used in other softwares.
Step 1 can be：Structure interpretation personnel are by the scanned copy of papery graph come structure interpretation layer position fault line.
Step 1 can also be：The numeral that structure interpretation personnel are made up of the N number of point of plane derived from relevant explanation software
Change line.
The method for drafting of oil reservoir middle small layer tomography of the present invention plane fault line will digitize always, and mark is numbered to it
Type is noted, the spatial data of tomography and unknown tomography up and down is further calculated, so as to derive unknown tomography by software programming
Data, so as to effectively draw the tomography of purpose substratum (middle substratum), improve the efficiency of tomography drafting and derive precision.
Brief description of the drawings
Fig. 1 is the flow chart of the method for drafting of oil reservoir middle small layer tomography described in the embodiment of the present invention；
Fig. 2 is the instance graph of the drafting of oil reservoir middle small layer tomography described in the embodiment of the present invention；
In figure, 1,7 sand group bottom surface tomography of shop hypomere, 2,9 sand group bottom surface tomography of shop hypomere, 3,8 groups of bottom surface tomographies of shop hypomere.
Embodiment
Below by non-limiting embodiment and with reference to attached drawing, the present invention is further illustrated：
As shown in Figure 1, an embodiment of the present invention provides a kind of method for drafting of oil reservoir middle small layer tomography, specific steps are such as
Under：
Step 1：The digitlization of known plane fault line；
Step 2：Known digitized fault line is numbered, and marks tomography upper lower burrs fault line type, it is convenient
The processing of programming mass；
Step 3：Upper stratigraphic horizon spatial data between tomography, lower tomography and unknown tomography known to calculating；
Step 4：Unknown layer data is derived, by software programming, derives unknown layer data in batches.Derive
Tomography is digitized for being used in other softwares.
Step 1 can be：Structure interpretation personnel are by the scanned copy of papery graph come structure interpretation layer position fault line.
Step 1 can also be：The numeral that structure interpretation personnel are made up of the N number of point of plane derived from relevant explanation software
Change line.
Specifically, as shown in Fig. 2, by taking 205 pieces of shop hypomere 7-9 sand group (N1g27-9) tomography translations of causeway oil field stake as an example：
1st, 9 sand group bottom surface tomography of known 7 sand group bottom surface tomography of shop hypomere and shop hypomere；
2nd, tomography is numbered：Same fault numbering is consistent and the starting point of trend is consistent；
3rd, according to geology achievement in research, determine that 205 pieces of shop hypomere 7-9 sand groups formation thicknesses of stake are 80m；
4th, 7 sand group of shop hypomere to 8 sand group formation thickness of shop hypomere is 30m, derives 8 sand group bottom surface tomography such as Fig. 1 of shop hypomere
It is shown.
The foregoing is merely the embodiment of the present invention, it is not intended to limit the invention, for this area
For technical staff, the invention may be variously modified and varied.That is made within the spirit and principles of the invention is any
Modification, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
