In this specification one or more embodiment, after obtaining logging curve, need to choose from logging curve Pretreatment zone, the pretreatment zone include at least a part of the log.Specifically, being selected in logging curve Take sub-fraction region as pretreatment zone, with mouse click selected areas the upper left corner and the lower right corner point can automatically by This region is stored in a new matrix, is then analyzed the matrix.Selected pretreatment zone is served only for color The extraction of characteristic can be any shape, herein with no restriction, due to the more convenient selection of rectangle, be typically chosen Rectangular area.It should be noted that selected pretreatment zone includes at least a part of the log, it is, institute The pretreatment zone of choosing must include the color characteristic data of log.

S2: removal interference data, the interference data include at least grid lines data, background from the pretreatment zone Chromatic number evidence.

In this specification one or more embodiment, due to often having grid lines, background colour etc. in the logging curve of acquisition Disturbing factor, so needing to remove interference data from the pretreatment zone after choosing pretreatment zone.

In this specification one or more embodiment, in the logging curve, the color of grid lines may be bent with well logging The color of line is identical may also be different, so can be using from different when from removal interference data in the pretreatment zone Reason mode.When the color characteristic data for the grid lines for including in the interference data and the color characteristic data of the log The color characteristic data for the grid lines for including when different or in the interference data is not in the color characteristic number of the log When according in preset range, by the way that colour gamut threshold values is arranged, the grid lines is filtered.Specifically, by the way that suitable color is arranged Thresholding first filters out all light colored mesh regions, then removes dark continuous net ruling part, obtains more pure curve number According to.

When the color characteristic data for the grid lines for including in the interference data and the color characteristic number of the log According to it is identical or it is described interference data in include grid lines color characteristic data the log color characteristic data When in preset range, the data in the pretreatment zone are saved in matrix, using the first preset rules to the matrix It is handled, realizes the filtering to the grid lines, the data in the pretreatment zone include at least the face of the grid lines The color characteristic data of color characteristic data and the log.Wherein, it is described using the first preset rules to the matrix into Row processing, realizes the filtering to the grid lines, comprising: convert two values matrix for the matrix；Utilize the first preset rules Full line in the two values matrix or permutation are deleted, first preset rules include continuously occurring in the two values matrix Full line or the quantity that is all selected of permutation reach preset value, or the quantity that the full line or permutation continuously occurred is selected reaches To preset value.

Specifically, when the color characteristic data of the grid lines is identical as the color characteristic data of the log or institute When stating the color characteristic data of grid lines in the color characteristic data preset range of the log, it is, in grid The color of the line part different from extracted graph color feature has been excluded, and only remains or pole consistent with graph color feature When its close meshing, since the data in the pretreatment zone being saved in matrix at this time and are converted into two-value Matrix, and grid lines is all located at a straight line vertically or horizontally and passes through so being all located at same a row or column in a matrix Full line or permutation element are analyzed in two values matrix, selected according to the full line or permutation that continuously occur in two values matrix The case where carry out grid lines deletion.Wherein, when the full line or permutation continuously occurred in two values matrix is all selected or connected When the quantity that the continuous full line occurred or permutation are selected reaches preset value, the row and column being selected is deleted.Wherein preset value can To be arranged according to the actual situation.It should be noted that when deleting the row or column in two values matrix, the data pixels point of curve May be deleted, even if data and curves data pixels point be deleted also only can be very little a part, this part can To carry out completion by interpolation method.

It may include background pixel in the logging curve of the acquisition in this specification one or more embodiment, So needing to carry out the pretreatment zone removal of background colour data.Under normal circumstances, the background pixel of image is white Pixel can first select the region of background color, obtain the value range of a background color pixel if being not white pixel, Then this partial pixel is deleted according to the value range of background color pixel.Specifically, according to the background of the logging curve Color information determines that the background colour data, the background colour information are predetermined；According to the background colour data, from institute It states and deletes the background colour data in the data of pretreatment zone.

In this specification one or more embodiment, if there is this very regular interference of other similar grid lines Element, again may be by carrying out matrix deleting operation and is removed.

S3: the color characteristic data of pixel in the pretreatment zone after obtaining removal interference data, it is special based on the color Sign data determine pixel characteristic search range.

Wherein, the color characteristic data of curve is exactly the data pixels feature of curve, is also data pixels point；Pixel characteristic Search range i.e. color feature value, are also character pixel, are the characteristic values based on a certain curve in coordinate, and what is referred to is exactly The color average that graph color is mostly in.

In this specification one or more embodiment, after removal interference data in the pretreatment zone, need pair The log for including in the pretreatment zone carries out the extraction of color feature value, that is, obtains the picture of the log Plain signature search range.Correspondingly, described determine pixel characteristic search range based on the color characteristic data, comprising: statistics The average value of the color characteristic data of pixel in the pretreatment zone obtains the pixel characteristic search range.Specifically, by Interference data are had been removed in pretreatment zone, so it is exactly that a large amount of color of log is special that pretreatment zone is remaining Data are levied, using color characteristic data as research object, its average value is counted, initial characteristic values is obtained, as log Color feature value, i.e. pixel characteristic search range provide foundation for subsequent extracted log pixel.Wherein, the institute is counted The average value of color characteristic data in pretreatment zone is stated, that is, the value of color characteristic data RGB is averaging processing, is obtained Color feature value to the characteristic value of more pervasive RGB, as the log.

It should be noted that in obtaining the pretreatment zone after removing interference data when the color characteristic data of pixel, If curve is unclear, still color characteristic number can be obtained by this method as long as the color characteristic that curve is also able to maintain it According to.If there is a plurality of log, and the color characteristic data of the color characteristic data of required curve and other curves of surrounding There is no apparent difference, it can be by the way that the color of this curve be modified with the pen of other colors, after then extracting modification The color characteristic data of curve.

S4: the pixel collection for meeting the pixel characteristic search range is obtained from the logging curve, according to institute It states pixel collection and determines the borehole log data extracted.

In this specification one or more embodiment, according to the pixel characteristic search range determined in step S3, from described The pixel collection for meeting the pixel characteristic search range is obtained in logging curve, to realize all pictures met the requirements Vegetarian refreshments is extracted from logging curve.Meet the pixel characteristic search specifically, obtaining from the logging curve The pixel collection of range, comprising: according to the pixel characteristic search range, determine the color model of pixel in log It encloses；According to the color gamut, characteristic range corresponding with the color gamut is selected；Based on the characteristic range, from described Pixel collection is obtained in logging curve.

In some embodiments, the pixel for meeting the pixel characteristic search range is being obtained from the logging curve After point set, further includes: the pixel in the pixel collection is become by corresponding position to the white area on gray level image Domain judges whether the white area is consistent with required log；As inconsistent, adjust after the color gamut adjusted Color gamut；Correspondingly, selecting spy corresponding with the color gamut after the adjusting according to the color gamut after the adjusting Levy range；Based on the characteristic range, pixel collection is obtained from the logging curve.Specifically, firstly, passing through step The pixel characteristic search range determined in S3 judges the data pixels point of log, determines pixel in log Color gamut, after determining color gamut, due to having preset each corresponding R, G, the feature value model of B characteristic value It encloses, as long as characteristic range determines that so having selected color gamut, then according to characteristic range, it is bent to traverse entire well logging The data pixels point for meeting characteristic range is remained, obtains all categories in logging curve by each pixel of line chart In the set of the point of this color characteristic range, i.e. acquisition pixel collection.Wherein, the selection of the color gamut is by setting What the function set was realized, color gamut principally falls into following region: black, red, green, blue, yellow, blueness The value of color, magenta, these color region characteristic values is different.Further, the characteristic value of color passes through three color therein Channel R, G, B are determined, wherein the value range of three chrominance channels between 0 to 255, can be led to three colors by reasonably dividing Road is greatly classified into following part:

Black: R < r+size, G < g+size, B <b+size

It is red: R>r-size, G<g+size, B<b+size

Green: R<r+size,G>g-size, B<b+size

Blue: R<r+size, G<g+size, B>b-size

Yellow: R>r-size, G<g+size, B<b+size

Cyan: R<r+size,G>g-size, B<b+size

It is pinkish red: R>r-size, G<g+size, B>b-size

Wherein, r, g, b indicate pixel characteristic search range, and the color gamut of selection is according to r, g, and the value of b determines, Size is the loose degree that color gamut is extracted for adjusting.It should be noted that general common figure can be at this Color is extracted in range, as occurred not identifying the range that oneself can manually adjust three colors until taking out curve by force.

In this specification one or more embodiment, size is the loose degree that color is extracted for adjusting, and size is got over Big value range is bigger, and the pixel of acquirement is more, and interference pixel is fewer；Opposite, the smaller value range of size is smaller, takes The pixel obtained is fewer, and it is more to obtain interference pixel.Specifically, acquired pixel collection can be become by corresponding position White area on gray level image simultaneously sees whether that it is big can to readjust color gamut if not being for the curve for desired taking-up It is small until suitable.Thus suitable data pixels point can be obtained by adjusting color gamut.

In this specification one or more embodiment, meets the pixel characteristic being obtained from the logging curve and search It, may be because before determining the borehole log data extracted according to the pixel collection after the pixel collection of rope range For by curve be made of dotted line, will appear a large amount of breakpoint area when being depicted as curve using the pixel collection of acquisition Domain will lead to the data extracted in this way and no longer link up, empty portions occurs.In order to obtain more accurate data, reach by The data visualization effect of acquisition, it is necessary to selectively be given up pixel in the pixel collection of acquisition and completion. Wherein, completion these do not have data pixels point position be mainly pass through connection null value position upper and lower ends point coordinate, then The completion of data pixels point is carried out using interpolation method.What embodiment utilized in this specification is Lagrange's interpolation, that is, It is linked up according to the curved portion before and after null value.It is further possible to carry out data pixels point using other interpolation methods Completion, this specification is without limitation.

In this specification one or more embodiment, is obtained from the logging curve and meet the pixel characteristic search After the pixel collection of range, before the borehole log data that extraction is determined according to the pixel collection, comprising: extract institute It states the pixel coordinate of every a line in pixel collection and averages, obtain the pixel coordinate under the coordinate；Obtain institute The starting pixels point coordinate and end pixels point coordinate for stating log described in pixel collection, delete the starting pixels point The pixel after pixel and end pixels point coordinate before coordinate；According to upper and lower pixel coordinate, interpolation is utilized Method carries out pixel completion to null value position.Specifically, firstly, extracting the pixel coordinate of every a line in the pixel collection And average, it finds and most suitable under the coordinate takes a position, i.e. pixel coordinate；Secondly, obtaining the pixel point set The starting pixels point coordinate and end pixels point coordinate of log described in conjunction, will be before starting pixels point coordinate and the picture of end Give up part after vegetarian refreshments coordinate；Then, the position for finding null value, according to the pixel coordinate pair of endpoint location before and after null value Null value position carries out interpolation, realizes the completion of pixel.It should be noted that if curve is very thick, in the same depth of needs On will appear multiple continuous pixels, at this moment only need to take midpoint therein to represent the data at this, that is to say, that Data will appear multi-group data under same coordinate, it is only necessary to retain one group closest to true value, so every a line refers to Be same level direction pixel, be to have taken average value as true under the coordinate pixel of same a line herein Real value.Under normal circumstances, under coordinate it is most suitable take to select position and refer to arithmetic average acquisition is carried out to institute capture vegetarian refreshments coordinate Value, be also possible to other way acquisition value, this specification to this with no restriction.

In this specification one or more embodiment, the borehole log data extracted is determined according to the pixel collection Afterwards, further includes: the borehole log data is depicted as line chart；Whether compare the line chart in the default mistake of the log In poor range, such as in the default error range, data value is converted according to equal proportion by the borehole log data and is protected It deposits.Wherein, equal proportion conversion is the coordinate for borehole log data being converted to the actual physics unit of data coordinates axis, the number It can be saved in table, can also be saved data value by other preserving types, herein with no restriction according to value.
