Description

Technical Field

[0001] The present invention belongs to the technical field of logging and drawing, and relates to a logging array curve imaging drawing method, system, device and medium. Background Art

[0002] Logging, as an important method and technology for exploring and developing oil and gas fields, brings higher economic benefits to the oil and gas industry. Logging data is generally divided into categories such as conventional logging curves, array curves, and production logging curves. Array curves are data generated by imaging logging instruments through physical parameter imaging of the wellbore wall and the physical problems around the well according to the observation of the geophysical field in the borehole. In the comprehensive mapping mainly based on two-dimensional drawing, array curves are usually presented in the form of imaging diagrams, which is convenient for more intuitive and in-depth analysis and research of data, and provides visual support for the application of logging data. With the progress of logging instruments, there are more and more downhole imaging instruments. The data volume of the array curves (M rows * N columns, with the depth index in the vertical direction) collected by imaging logging instruments is relatively large. For example, the longitudinal sampling accuracy of micro-resistivity scanning imaging reaches 2 mm, and the number of radial sampling points of array acoustic waves exceeds 1000. The size of a single array curve is as small as several hundred megabytes and as large as several gigabytes, which places higher requirements on the performance of the computer. Operations such as scrolling and browsing of imaging diagrams by users all require re-reading of array data and mapping, which seriously consumes computer resources, is very slow, and has serious lags. Especially in the case where most of the logging data processing, interpretation and mapping work still mainly uses ordinary computers, it brings great challenges to the imaging drawing of logging array data and seriously affects the logging data processing and interpretation work. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that in the prior art, the data volume of array curves is relatively large, and the existing logging data processing, interpretation and mapping equipment cannot meet the needs of imaging drawing of logging array data, and to provide a logging array curve imaging drawing method, system, device and medium.

[0055] Refer to Figure 1 , the present invention discloses a logging array curve imaging drawing method, including:

[0056] S101, collecting logging array curves;

[0057] S102, based on the size of the visible drawing area, cropping the collected logging array curves to obtain the logging array curve data inside the visible drawing area;

[0058] The logging array curve data inside the visible drawing area specifically includes: the starting depth, ending depth, sampling interval, horizontal data dimension, number of pixel columns in the drawing area, number of pixel rows in the drawing area, bottom pixel corresponding to the logging map, top pixel corresponding to the logging map, upper boundary pixel position of the pixel range of the visible drawing area, lower boundary pixel position of the pixel range of the visible drawing area, ending depth of the visible drawing area, starting depth of the visible drawing area, horizontal starting dimension index and horizontal ending dimension index of the array data.

[0059] Determine the corresponding upper boundary depth and lower boundary depth of the array curve according to the upper and lower boundaries of the pixel range of the visible area, as shown in formulas (1) and (2):

[0060] tdep = tw / (we - ws) * (edep - sdep) + sdep (1)

[0061] bdep = bw / (we - ws) * (edep - sdep) + sdep (2)

[0062] Among them, tdep is the depth of the upper boundary of the array curve within the pixel range of the visible drawing area, and bdep is the depth of the lower boundary of the array curve within the pixel range of the visible drawing area; tw is the pixel position of the upper boundary of the pixel range of the visible drawing area; bw is the pixel position of the lower boundary of the pixel range of the visible drawing area; we is the bottom pixel corresponding to the log plot; ws is the top pixel corresponding to the log plot; edep is the end depth corresponding to the log plot; sdep is the starting depth corresponding to the log plot.

[0063] S103, divide the visible drawing area into several sub-regions, and draw based on the log array curve data corresponding to the sub-regions;

[0064] S104, based on the array data interval corresponding to each visible drawing pixel row in the vertical direction and the data interval corresponding to each visible drawing pixel column in the horizontal direction, obtain the array data required for drawing in the visible drawing area;

[0065] The array data interval corresponding to each drawing pixel row in the vertical direction is specifically: thin out the number of pixel rows in the drawing area to obtain the thinned number of pixel rows in the drawing area; among them, the array data interval corresponding to each drawing pixel row in the vertical direction is:

[0068] The data interval corresponding to each visible drawing pixel column in the horizontal direction is specifically: thin out the number of pixel columns in the drawing area to obtain the thinned number of pixel columns in the drawing area; among them, the data interval corresponding to each visible drawing pixel column in the horizontal direction is:

[0070] Among them, HI is the data interval corresponding to each device pixel column in the horizontal direction; EP and SP are the horizontal start dimension index and horizontal end dimension index of the array data respectively; D is the number of pixel columns in the drawing area.

[0071] S105, based on the obtained array data required for drawing, obtain the drawing of the sub-region;

[0073] Vertically divide the image into several regions with the same height, and perform the drawing operation in each drawing region in parallel; the height for image division is determined as shown in formula (5):

[0074] Num = imgH / baseH (5)

[0075] where Num is the number of vertically divided sub-images of the image, with a minimum of 1, imgH is the total pixel height of the image; baseH is the reference height for image division, generally set to 200 pixels;

[0078] where bottomH is the height of the last drawing segment; imgH % baseH is the remainder.

[0079] See Figure 2 , the present invention discloses a logging array curve imaging drawing system, including:

[0080] An acquisition module, which acquires logging array curves;

[0081] A clipping module, which clips the acquired logging array curves based on the size of the visible drawing area to obtain the logging array curve data inside the visible drawing area;

[0082] A division module, which divides the visible drawing area into several sub-regions and performs drawing based on the logging array curve data corresponding to the sub-regions;

[0083] A first acquisition module, which acquires the array data required for drawing in the visible drawing area based on the array data interval corresponding to each visible drawing pixel row in the vertical direction and the data interval corresponding to each visible drawing pixel column in the horizontal direction;

[0084] A second acquisition module, which acquires the drawing of the sub-region based on the acquired array data required for drawing;

[0085] A third acquisition module, which performs parallel drawing of the drawing of the sub-region to obtain the image of the overall logging array curve.

[0086] Embodiment:

[0087] The present invention provides a logging array curve imaging drawing method, as Figure 3 shown, including the following steps:

[0088] Step S1: Obtain information such as the depth range, sampling interval, and lateral data dimension of the curve. Read information such as the starting depth, ending depth, sampling interval, and lateral data dimension of the curve. Obtain information such as the starting depth, ending depth, sampling interval, and lateral data dimension of the array curve.

[0089] Step S2: Obtain the number of pixel rows and pixel columns in the drawing area. Obtain the number of pixel rows and pixel columns in the visible area of the mapping device.

[0090] Step S3: Drawing area and data clipping; Clip the drawing area and data according to the visible area of the device (such as a computer screen). For example, the drawing range is 0 - 1000 meters, but due to the limitations of the device size of a display device such as a computer, the actual visible drawing area may be 500 - 600 meters. Then only read the array curve data of 500 - 600 meters and only draw for this 100 - meter visible area. Compared with the drawing of 0 - 1000 meters, the amount of data to be read is greatly reduced, effectively reducing the time consumption of reading the array curve, and the improvement of the drawing efficiency is very obvious. At the same time, in order to prevent jitter during the drawing scrolling process, usually expand the upper and lower boundaries of the visible area after clipping by 50 - 200 pixel areas as the actual drawing area. Through the clipping of the drawing area and data, the drawing efficiency is greatly improved.

[0091] Step S4: Array data thinning; As Figure 4 shown, in the logging array curve recording format, vertically is the depth information with an equal sampling interval, and horizontally is the array information with an equal interval. The array data needs to be imaged and drawn on the drawing device by converting each data point of the array data into a color value and filling it to the corresponding pixel point. Read the array data required for drawing according to the calculated array data interval corresponding to each pixel row in the vertical direction and the data interval corresponding to each pixel column in the horizontal direction, reducing the amount of data read and the number of pixel drawings, and the drawing efficiency is significantly improved.

[0092] The calculation formulas for the array data interval corresponding to each pixel row in the vertical direction and the data interval corresponding to each pixel column in the horizontal direction are as follows:

[0093] VI = (VE - SE) / STEP / PV

[0094] Where, VI is the data interval corresponding to each row of device pixels in the vertical direction; VE is the ending depth of the visible area; SE is the starting depth of the visible area; STEP is the sampling interval of the array curve; PV is the number of pixel rows in the drawing area.

[0095] HI = (EP - SP + 1) / D

[0096] Wherein, HI is the data interval corresponding to each column of device pixels in the horizontal direction; EP and SP are the horizontal start dimension index and the horizontal end dimension index of the array data respectively; the start dimension index and the end dimension index are at least 1 and at most the horizontal dimension of the array curve; D is the number of pixel columns in the drawing area.

[0097] Step S5: Parallel mapping of array data; As Figure 5 and Figure 6 shown, construct an image of the same size according to the visible drawing area, then vertically divide the image into several regions with the same height, then complete the drawing action in parallel in each drawing area, and finally project the entire image onto the drawing device.

[0098] The formula for determining the height of image segmentation is as follows:

[0099] Num = imgH / baseH

[0100] Wherein, Num is the number of vertically segmented sub-regions of the image, at least 1, imgH is the total pixel height of the image. baseH is the reference height for vertical segmentation of the image, generally set to 200 pixels. The height of the first Num - 1 images is baseH, and the height of the last sub-image is

[0101] bottomH = baseH + imgH % baseH

[0102] In the formula, bottomH is the height of the last sub-image.
