Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
FIG. 1A is a flow chart illustrating a method for generating a multi-button while drilling electrical imaging image according to an embodiment of the invention. As shown in fig. 1A, the method comprises the steps of:
and S101, performing time-depth conversion on the acquired time domain electric buckle data of the plurality of electric buckles to obtain depth domain electric buckle data.
Specifically, data acquired by a plurality of electric buttons of the multi-electric-button drilling electric imaging instrument is time domain electric button data, and in order to improve the generated image quality, time-depth conversion needs to be performed on the acquired time domain electric button data of the plurality of electric buttons, and the electric button data recorded by the time index is converted into the electric button data recorded by the depth index, that is, the time domain electric button data is converted into the depth domain electric button data. Specifically, the time-depth conversion method may use a method in the prior art, for example, a direct scaling method and/or a graph shift method, which is not described here. The depth domain power-clip data is power-clip data related to the measured depth.
After the depth domain electric buckle data are obtained, the electric buckle data on each depth recording point can be expanded according to the geographical north pole by combining the azimuth measurement curve and the magnetic declination information.
And step S102, for any electric buckle, carrying out grid division on the electric buckle data in the depth domain based on the depth and the azimuth interval to obtain a first grid data result corresponding to each grid of the electric buckle.
Specifically, a depth-azimuth interval two-dimensional grid is created, for any electric buckle, grid division is carried out on each depth domain electric buckle data according to the depth and azimuth interval to which the electric buckle belongs, and a first grid data result corresponding to each grid of the electric buckle can be obtained through the grid division, wherein the first grid data result reflects the number of first grid data in the grid and a specific numerical value of the first grid data. However, due to irregular motions of the multi-buckle while-drilling electric imaging instrument, such as non-uniform rotation, drill jamming and drill backing, some grids may have data, and some grids may not have data.
For convenience of understanding, a plurality of electrical buckles of the multi-electrical buckle while drilling electrical imaging instrument are respectively named as A, B, C and the like, and assuming that the multi-electrical buckle while drilling electrical imaging instrument rotates for one circle, and a single electrical buckle can complete i times of data acquisition in the circle, i azimuth intervals can be defined on each depth point. Assuming that a total of j depth points are measured in the depth measurement section, the data of the k azimuth interval of the electric buckle A at the j depth point can be represented as Ajk. Table 1 shows the first grid data results (grid blank indicates data missing) of the electric buckle a corresponding to each grid.
When the multi-electric-button electrical imaging while drilling instrument has N electric buttons, N first grid data results can be obtained after the processing according to the step.
Table 1:
| depth of field | Azimuth interval 1 | Azimuth interval 2 | Azimuth interval 3 | …… | Azimuth interval i |
| Depth 1 | A11 | A12 | A13 | …… | A1i |
| Depth 2 | A21 | A23 | …… | A2i | |
| Depth 3 | A31 | A32 | …… | A3i | |
| …… | …… | …… | …… | …… | …… |
| Depth j | Aj1 | Aj2 | Aj3 | …… | Aji |
Step S103, aiming at grids in the same depth and the same azimuth interval, grid data merging processing is carried out according to the first grid data results corresponding to the electric buckles, and second grid data results corresponding to the electric buckles on the grids are obtained.
In order to generate an image that can reflect the formation characteristics more truly by making full use of the data acquired by the plurality of electric deductions, it is necessary to merge the data of the plurality of electric deductions, that is, merge the first mesh data results of the meshes in which the plurality of electric deductions are at the same depth and in the same azimuth interval. Specifically, for grids in the same depth and in the same azimuth interval, grid data merging processing is performed according to first grid data results corresponding to the plurality of electric buckles, so that second grid data results corresponding to the plurality of electric buckles on the grids are obtained, wherein the second grid data results reflect the number of second grid data in the grids and specific numerical values of the second grid data.
Continuing with the above example, table 2 shows the second mesh data results corresponding to a plurality of electric buckles on the mesh after the mesh data merging process.
Table 2:
due to irregular movement of the multi-buckle while-drilling electric imaging instrument, the number of data falling into each grid is different, some grids may have data, and the number of data in the grids is different and some grids may have no data. It should be noted that, a single electric deduction may not have data in a certain grid, however, after the grid data merging process, since other electric deductions have data in the grid, finally, a plurality of electric deductions have data in the grid.
Therefore, after the mesh data merging process, the following process is also required:
and step S104, if the second grid data result shows that the number of the second grid data falling into the grid is not 0, determining a plurality of electric deduction grid data electrically deducted in the grid according to the second grid data.
For the case that the second grid data exists in the grid, the electric deduction grid data of the plurality of electric deductions on the grid can be determined according to the second grid data, and when the number of the second grid data is different, the electric deduction grid data of the plurality of electric deductions on the grid are determined in different manners:
if the second grid data result shows that the quantity of the second grid data falling into the grid is a first numerical value, determining the second grid data as a plurality of electric deduction grid data electrically deducted in the grid;
if the second grid data result shows that the number of the second grid data falling into the grid is a second numerical value, calculating the average value of the second grid data, and determining the average value as a plurality of electric deduction grid data electrically deducted in the grid;
if the second grid data result shows that the number of the second grid data falling into the grid is a third numerical value, calculating the difference between the second grid data and other second grid data aiming at any second grid data; determining a plurality of electric deduction grid data electrically deducted from the grid according to the differences, for example, determining a plurality of electric deduction grid data electrically deducted from the second grid data with the smallest differences;
if the second grid data result of the grid indicates that the number of the second grid data falling into the grid is larger than a third numerical value, calculating the difference between the second grid data and other second grid data aiming at any second grid data, screening the second grid data according to the difference, and determining a plurality of electric deduction grid data electrically deducted from the grid based on the screened second grid data and corresponding weights; wherein the first value is less than the second value, and the second value is less than the third value.
Specifically, if the second grid data result indicates that the number of the second grid data falling into the grid is 1, determining the second grid data as a plurality of electric deduction grid data electrically deducted from the grid;
if the second grid data result shows that the number of the second grid data falling into the grid is 2, calculating the average value of the 2 second grid data, and determining the calculated average value as a plurality of electric deduction grid data electrically deducted in the grid;
if the second grid data result indicates that the number of the second grid data falling into the grid is 3, assuming that 3 second grid data are a, b, and c, calculating the difference between each second grid data and the other two second grid data, defining da as the difference between the a data and the b, c data, defining db as the difference between the b data and the a, c data, and defining dc as the difference between the c data and the a, b data, wherein the difference can be calculated by referring to the following formula:
da＝(|a–b|+|a–c|)/2
db＝(|b–a|+|b–c|)/2
dc＝(|c–a|+|c–b|)/2
then, determining a plurality of electric deduction grid data electrically deducted from the grid according to the differences, for example, determining a plurality of electric deduction grid data electrically deducted from the second grid data with the smallest difference, and for the differences da, db and dc, if da is the smallest, determining the second grid data a as the plurality of electric deduction grid data electrically deducted from the grid; determining the second mesh data b as a plurality of electrically deducted mesh data electrically deducted at the mesh if db is minimum; if dc is minimum, the second mesh data c is determined as a plurality of electrically deducted mesh data electrically deducted at the mesh.
If the second mesh data result indicates that the number of the second mesh data falling within the mesh is greater than or equal to 4, the following process may be performed:
assuming that the number of the second mesh DATA falling within the mesh is N, the second mesh DATA falling within the mesh are defined as DATA, respectively1,DATA2,…,DATANDefining the difference between the ith second grid data and other second grid data as DiThen D can be calculated by the following formulai：
Di＝(DATAi-DATA1)2+(DATAi-DATA2)2+…+(DATAi-DATAN)2/N
The difference between any one second grid data and the other second grid data is calculated and is denoted as D1,D2,…,DN。
To D1,D2,…,DNPerforming a sorting process, for example, ascending or descending, and filtering out the second grid DATA with a larger difference in a preset ratio, for example, filtering out 10% or 20% of the second grid DATA with a larger difference than the remaining second grid DATA, assuming that the remaining second grid DATA is DATAa,DATAb,…,DATAMThen, the weight of each of the remaining second mesh data may be calculated by a method in which the weight of each of the second mesh data is defined as Ca,Cb,…,CMThe weight calculation formula is as follows:
Ca＝1-DATAa/(DATAa+DATAb+…+DATAM)
Cb＝1-DATAb/(DATAa+DATAb+…+DATAM)
CM＝1-DATAM/(DATAa+DATAb+…+DATAM)
finally, a plurality of electric deduction grid data of electric deduction on the grid can be determined according to the following formula
DATAa*Ca+DATAb*Cb+…+DATAM*CM
Optionally, second grid data with a large difference in a preset ratio can be filtered out, an average value of the remaining second grid data is calculated, and the average value is determined as a plurality of electric deduction grid data electrically deducted in the grid.
Step S105, if the second grid data result shows that the number of the second grid data falling into the grid is 0, determining a plurality of electric deduction grid data electrically deducted from the grid according to the second grid data corresponding to other grids in the first preset direction.
In order to avoid the problem of local image loss, data supplementation needs to be performed on the grid under the condition that second grid data do not exist in the grid, and specifically, according to second grid data corresponding to other grids in the first preset direction, a plurality of electric deduction grid data electrically deducted to the grid are determined. The first predetermined direction may be above, below, left and/or right, or may be other directions, such as above-left, above-right, etc.
According to the second grid data corresponding to other grids in the first preset direction, determining a plurality of electric deduction grid data electrically deducted from the grid is further realized by the following method:
if the second grid data result shows that the number of the second grid data falling into the grid is 0, searching and searching the grid with the number of the second grid data falling into the grid not being 0 in a plurality of second preset directions;
and determining a plurality of electric deduction grid data of electric deduction on grids according to the searched second grid data corresponding to the grids with the number of the second grid data falling into the grids not being 0.
Specifically, the first preset direction includes a plurality of second preset directions, for example, four directions including up, down, left, and right, then the search is performed in the up, down, left, and right directions, respectively, until a grid with the number of second grid data being not 0 is found, then an average value of the second grid data in the searched grid is calculated, and the average value is determined as a plurality of electric deduction grid data of the grid.
More specifically, the method is realized by the following steps: aiming at any second preset direction, taking a grid adjacent to the grid with the second grid data number of 0 as a starting point, and searching and judging whether the second grid data number in the grid is 0 or not one by one along the second preset direction;
if the grid with the number of the second grid data falling into the grid not being 0 is searched, stopping searching;
if the grid with the second grid data number of 0 falling into the grid is searched, judging whether the grid is the last grid in the second preset direction; if not, continuing searching; if yes, stopping searching and abandoning the second preset direction;
and after stopping searching in each second preset direction, determining the electric deduction grid data of a plurality of electric deductions on grids according to the searched second grid data corresponding to the grids with the number of the second grid data falling into the grids not being 0. And if a certain direction is searched to reach the last grid and no data is found, abandoning the direction, calculating the average value of the second grid data in the grids found in the other directions, and determining the average value as the electric deduction grid data of a plurality of electric deductions on grids.
And step S106, generating a multi-electric-button electrical imaging while drilling image according to the electric button grid data of the electric buttons on each grid.
In combination with the above example, table 3 shows the determined electric deduction grid data of a plurality of electric deductions on grids, where electric deduction grid data exists in each grid, and after the above processing, the number of electric deduction grid data in the grid is all 1.
Table 3:
| depth of field | Azimuth interval 1 | Azimuth interval 2 | Azimuth interval 3 | …… | Azimuth interval i |
| Depth 1 | V11 | V12 | V13 | …… | V1i |
| Depth 2 | V21 | V22 | V23 | …… | V2i |
| Depth 3 | V31 | V32 | V33 | …… | V3i |
| …… | …… | …… | …… | …… | …… |
| Depth j | Vj1 | Vj2 | Vj3 | …… | Vji |
When the electrical imaging while drilling instrument works underground, a certain gap exists between the measuring electrical button and the well wall, and part of current can be shunted from mud in the gap, so that the measured value of the electrical button is reduced. Because the instrument cannot be completely centered in the measurement process, the gap between the instrument and the borehole wall is always changed, so that the current intensity shunted from the slurry is also changed, finally, different electric deduction measurement values are generated on the stratum with relative resistivity, and the stratum with relative resistivity is represented as a strip-shaped characteristic with inconsistent brightness on an image, in order to further eliminate the condition of inconsistent brightness of the generated image, the following processing can be further carried out:
