[0047] Logging electrical imaging blank strip filling plays an important role in describing the integrity of solution pores, fractures and gravel particles in carbonate reservoirs and glutenite reservoirs, and is an important logging electrical imaging data preprocessing step for accurately calculating secondary porosity and dividing glutenite facies.

[0048] Under the prior art, OpenMP multi-core CPU parallel technology is mostly used on a local host to accelerate the blank strip filling calculation. However, due to the limitation of the number of CPU cores of the local host, the existing technology inevitably has the problem of too long calculation time when processing continuous long well sections of electrical imaging data.

[0049] Therefore, in order to solve the above technical problems, the present disclosure provides a well logging electrical imaging blank strip filling method, which can be used for rapid filling of well logging electrical imaging blank strips. The method can dynamically construct a heterogeneous cluster composed of a master node and multiple slave nodes according to available computers on the network; then the host performs data preprocessing, task scheduling and slave node data distribution. The nodes in the cluster simultaneously execute the deployed electrical imaging blank strip filling program; the server process on the local host is responsible for summarizing the filling processing results of each slave node. Finally, the host performs data post-processing to generate the filling results of the entire well section.

[0050] Example One

[0051] The embodiment discloses a well logging electrical imaging blank strip filling method applied to a first terminal.

[0052] Figure 1 A flowchart of a well logging electrical imaging blank strip filling method provided by the embodiment of the present disclosure is shown in FIG. 1. Figure 1 As shown in FIG. 1, the method comprises the following steps.

[0053] Step 110: Preprocessing the full well section electrical imaging data to obtain multiple sub-data files with the same size.

[0054] Specifically, the first terminal can be a high-performance host, also known as a master node; a plurality of computers heterogeneous to the host are used as slave nodes; the computers can be ordinary performance computers with the same software and hardware systems. The electrical imaging blank strip filling program is deployed on the master node and each slave node.

[0055] Optionally, the sub-data file can be a data file with a file name serial number.

[0056] According to the electrical imaging data, generate full well section grayscale image data and filling mask template data; according to a fixed height, continuously cut the grayscale image data and the mask template data into multiple sections, and store them as multiple sub-data files with continuous serial number identifiers in the file names. For example, each sub-data file contains 200 rows of data, or each sub-data file contains 500 rows of data, and so on.

[0057] Step 120: Determine the number of second terminals and send the multiple sub-data files to the second terminals.

[0058] Optionally, the high-performance host detects available ordinary performance computers through a network to dynamically form a computer cluster composed of a master node and multiple slave nodes.

[0059] In some embodiments, the sending of the multiple sub-data files to the second terminals comprises:

[0060] Based on the load balancing strategy, determine the number of sub-data files to be processed in each second terminal;

[0061] For any second terminal, based on the number of files and according to a preset distribution strategy, the target sub-file to be processed by the second terminal is determined from all the sub-data files, and the target sub-file is sent to the second terminal.

[0062] In some embodiments, determining the number of sub-data files to be processed by each second terminal includes:

[0063] Based on a load balancing strategy, the number of sub-data files to be processed by each second terminal is determined according to a preset file count determination model; wherein, the preset file count determination model includes:

[0064] N sub *T sub =(N total -N sub *M)*T host

[0065] Among them, T sub T host These represent the file processing time for the second terminal to process one sub-data file and the file processing time for the first terminal to process one sub-data file, respectively; M is the number of second terminals; N is the number of second terminals. sub The number of sub-data files to be processed for each second terminal; N total This represents the number of files in all sub-data files.

[0066] The processing time for processing a sub-data file can be determined based on historical data, and the average of all historical data is used as the terminal's processing time.

[0067] The above formula can be used to determine the number of sub-data files to be loaded (processed) for each child node.

[0068] In some embodiments, it also includes:

[0069] The number of remaining files is determined based on the number of all sub-data files and the total number of files.

[0070] If the number of remaining files is greater than 0, the remaining target sub-files to be processed by the first terminal are determined from all the sub-data files according to the preset distribution strategy based on the number of remaining files, and the remaining target sub-files are filled.

[0071] The master node can determine which specific sub-data files need to be distributed to each sub-node according to a preset distribution strategy. The preset distribution strategy can be set according to actual needs.

[0072] Optionally, the master node can use FTP (File Transfer Protocol) network service to distribute the data files of the entire well section to the child nodes in sequence by consecutive labels. The remaining data files are treated as local data and processed by the master node.

[0073] Understandably, in practical applications, the master node can be used to process sub-data files or not.

[0074] Step 130: Issue a data filling command to control the second terminal to fill the received sub-data files, and after completing the filling process, return the filling results of each sub-data file.

[0075] Optionally, the master node can initiate the filling procedure on the child nodes through the secure shell protocol service of each child node, so that each child node can perform calculations on its own sub-data files.

[0076] Furthermore, the electro-imaging blank strip filling program is a morphological component analysis method program based on automatic detection of filling result quality; the morphological component analysis method program sets a small initial number of iterations. After calculation, the filling quality is checked. If the quality is qualified, the program exits. If the quality is unqualified, iterative calculation continues, and at the same time, the soft threshold shrinkage range is automatically increased to enable the morphological component analysis method program to converge quickly until the filling quality is qualified; the electro-imaging blank strip filling program can be deployed on both the master node and child nodes, and the electro-imaging blank strip filling program is compatible with the hardware and software systems of the computers on the respective nodes.

[0077] The master node starts a server process on its local machine, listening for messages sent by each child node via sockets. Each child node, acting as a client, sends a completion message to the server process after completing its calculation. The server process receives the message through the socket, parses the IP address of the sending client, and reads the filling result from the corresponding child node via FTP network service, storing it on the master node's local machine.

[0078] Step 140: In response to receiving the filling processing results of all sub-data files, post-process all filling processing results, and then obtain the filling results of the entire well section through heterogeneous calculation.

[0079] After the master node completes its local data calculations, it sends a query message to the server process via an inter-process message communication mechanism. The server process, upon receiving the results from all child nodes, returns a response message. Alternatively, each child node can proactively send its filling results back to the master node after completing the filling process.

[0080] The master node identifies the filling results by consecutive serial numbers in the file names of all filling processing results, forms the filling result data for the entire well section, and converts the filling results into logging data based on the color scale of the electrical imaging map and the maximum and minimum values ​​of the logging data at the time of mapping, and stores it in the current logging data file.

[0081] In some embodiments, it also includes:

[0082] In response to the data display operation, display the filling results of the entire well section; and / or

[0083] In response to the data export operation, the filling results for the entire well section are exported.

[0084] Optionally, the master node can provide user-interactive functions such as mapping of electrical imaging data and display of filling results. When exporting the filling results of the entire well section, the filling results can be displayed through the I / O interface of the master node device, such as a USB interface; the filling results of the entire well section can also be displayed through the display of the master node device.

[0085] Example Two

[0086] Based on the above embodiments, this embodiment further explains and illustrates the method for filling blank strips in well logging electrical imaging disclosed in this application.

[0087] In some embodiments, determining the number of sub-data files to be processed by each second terminal includes:

[0088] Based on the historical data of the first terminal, determine the file processing time of the first terminal for processing a sub-data file;

[0089] Based on the historical data of each second terminal, determine the file processing time for each second terminal to process one sub-data file;

[0090] Based on the file processing time of the first terminal and the file processing time of all second terminals, determine the number of sub-data files to be processed by the first terminal and the number of sub-data files to be processed by each second terminal.

[0091] The historical data mentioned above represents the time (i.e., processing time) that the first or second terminal previously spent processing sub-data files. The average of all historical data can be used as the terminal's processing time.

[0092] Understandably, given that each child node has computers with different performance levels, further improvements in processing efficiency could be achieved by allocating the number of child data files based on the performance of each child node's computer.

[0093] Example Three

[0094] This embodiment provides a method for filling blank strips in well logging electrical imaging, which is applied to a second terminal.

[0095] Specifically, the first terminal can be a high-performance host, also known as the master node; multiple computers heterogeneous with the host serve as child nodes; the computers can be ordinary-performance computers with the same hardware and software systems. An electro-imaging blank strip filling program is deployed on both the master node and each child node.

[0096] Specifically, after the second terminal receives one or more sub-data files sent by the first terminal, it responds to the data filling instruction sent by the first terminal, performs filling processing on the received sub-data files, and feeds back the filling processing results of each sub-data file after the filling processing is completed.

[0097] Example Four

[0098] Based on the above embodiments, this embodiment provides a method for filling blank strips in well logging electrical imaging.

[0099] Figure 2 This is a schematic flowchart illustrating another method for filling blank strips in well logging electrical imaging, provided as an embodiment of this disclosure. Figure 2 As shown, the method includes:

[0100] Step 210: Control the first terminal to preprocess the electrical imaging data of the entire well section to obtain multiple sub-data files of the same size;

[0101] Step 220: Determine the number of second terminals and control the first terminal to send the multiple sub-data files to the second terminals according to the load balancing strategy;

[0102] Step 230: Control the first terminal to send a data filling instruction so that the second terminal can fill the received sub-data file;

[0103] Step 240: In response to the data filling instruction, control the second terminal to fill the received sub-data files, and after completing the filling process, feed back the filling results of each sub-data file to the first terminal.

[0104] Step 250: In response to receiving the filling processing results of all sub-data files, control the first terminal to perform post-processing on all filling processing results, and then obtain the filling results of the entire well section through heterogeneous computing.

[0105] The specific execution steps of the logging electrical imaging blank strip filling method disclosed in this embodiment can be referred to the aforementioned embodiment in each terminal, and will not be repeated here.

[0106] Example Five

[0107] Based on the above embodiments, this embodiment provides a specific example.

[0108] In this embodiment, a high-performance HP workstation and multiple ordinary-performance Sun workstations are used as application examples to illustrate the method disclosed in this application.

[0109] The HP workstations are equipped with a Windows 10 operating system and an Intel i7 processor (3.2GHz); the Sun workstations are equipped with a Sun Solaris 9 operating system and a SPARC V9 processor (1.6GHz).

[0110] Step S101: The HP workstation detects available Sun workstations via the network. In this example, there are 8 available Sun workstations. A heterogeneous computer cluster is established, with the HP workstation as the master node and the 8 Sun workstations as child nodes, and the electron microscopy blank strip filling program is deployed.

[0111] In step S102, the master node performs data preprocessing, splits the electrical imaging data of the long well section, and forms multiple data files of the same size with filename sequence numbers.

[0112] Step S103: The master node calculates the load on the child nodes and distributes the corresponding data files to the child nodes.

[0113] Step S104: The master node starts the filling process for each child node.

[0114] Step S105: After the master node starts the local server process, it starts the local filling program.

[0115] In step S106, after receiving the response message from the server process, the master node performs data post-processing to form the filling result.

[0116] By comparing computation time, the computation efficiency of cluster computing is about 40% higher than that of computing entirely on HP workstations. In theory, the cluster computing method can greatly shorten the computation time of electrical imaging data in long well sections and greatly improve processing efficiency simply by increasing the number of available child nodes.
