The unitization normal vector of each measurement point on well logging projection track.
By the unitization purpose of vector it is to determine any position log data that fathoms to realize in the embodiment of the present application
Display normal vector, and meet reach the effect that normal vector is seamlessly transitted between well flex point.
Wherein, the unitization vector of each orbit segment of determination can be：
The vector of the orbit segment can be determined according to the corner position at orbit segment two ends, it is then that the vector of the orbit segment is single
Positionization, so that the unitization vector of fixed track section.It is described it is unitization vector for example can according to formula：
WithIt is determined that each orbit segment
Unitization vector；
Wherein, aiFor the unitization vectorial abscissa of i-th of orbit segment；biFor the unitization vectorial of i-th orbit segment
Ordinate；xiAnd xi+1The abscissa of i-th and i+1 flex point respectively on well logging projection track；yiAnd yi+1Respectively log well
Project the ordinate of i-th and i+1 flex point on track.As shown in fig. 6, having (x on a well logging projection track1, y1)、(x2,
y2) and (x3, y3) three flex points.The vector of so first orbit segment is (x2-x1, y2-y1).It is then corresponding, after its is unitization
Vector is (a can be used1, b1) represent.Therefore, log well
The unitization normal vector for projecting first orbit segment on track is (- b1, a1).Based on identical method, each track can be asked for
The unitization vector of section.
Wherein, the unitization vector of each orbit segment of the basis determines each measurement point on the well logging projection track
Unitization normal vector, is specifically as follows：
For each orbit segment, first according to formula a=a1(1-rj)+a2rjAnd b=b1(1-rj)+b2rjDetermine the well logging
Project the normal vector of each measurement point on track.Then the unitization well logging projects the normal direction of each measurement point on track again
Amount, obtain each measurement point on the well logging projection track unitization normal vector (refer to unitization vector approach above,
It will not be repeated here).
Wherein, a and b are respectively the abscissa and ordinate of the normal vector of j-th of measurement point on well logging projection track；a1With
a2The abscissa of first flex point and second flex point respectively in the orbit segment；b1And b2Respectively first in the orbit segment
The ordinate of flex point and second flex point；rjFor the coefficient of j-th of measurement point in the orbit segment, and rj=B/A, wherein, B is jth
Individual measurement point is to the length of first flex point, and A is the length between first flex point and second flex point.
Secondly, the unitization normal vector of each measurement point and the water of correspondence log data on track are projected according to the well logging
Flat offset, determines the log data point display location of each measurement point correspondence log data on the well logging projection track.
It is described according to the unitization normal vector of each measurement point on the well logging projection track and right in the embodiment of the present application
The horizontal offset of log data is answered, the log data of each measurement point correspondence log data on the well logging projection track is determined
Point display location, can include：
According to formula x=xgui+ a'w and y=ygui+ b'w determines that each measurement point correspondence is surveyed on the well logging projection track
The log data point display location of well data；
Wherein, x and y are respectively the abscissa and ordinate of the log data point of the corresponding log data of each measurement point；xgui
And yguiThe abscissa and ordinate of the unitization normal vector of respectively each measurement point；W is each measurement point correspondence log data
Horizontal offset.
Finally, log data is drawn according to the log data point display location.
S103, the dip direction for determining each measurement point on the well logging projection track, and according to the ground of each measurement point
Layer tendency draws corresponding log analysis data.
In the embodiment of the present application, log analysis data can include hierarchical information.Wherein, it is described to determine the well logging projection
Each measurement point and seismic reflection are special on the dip direction of each measurement point on track, such as the projection track that can be logged well according to
The determination dip direction levied, then dip direction display layering.As shown in Figure 7, it is assumed that the point at layer position two ends is piont1,
Point2, angle of inclination angle=atan2 (point2._y-point1._y, point2._x-point1._x)；In drawing
When draw out geological layering using the angle.
In one exemplary embodiment of the application, it can obtain as shown in Figure 9 cutd open in earthquake after completing the procedure
