Log data format automatic identification and conversion method based on database

Abstract

The invention relates to a log data format automatic identification and conversion method based on a database. The method comprises the steps of: analyzing information characteristics of various log data formats, extracting characteristic information from the information characteristics to establish a data format characteristic base, matching a data file to be converted with the information in the characteristic base so as to quickly identify the data format type of the data file, and then, invoking a matched data format conversion module for carrying out exact match and then carrying out scanning and conversion on the data file. In the method, by adopting a characteristic base technology, the match of the data format is firstly matched with the characteristic base, thus, the data format type can be ensured to be quickly identified, the identification accuracy is improved and the manual intervention and labor intensity are lowered; and the part of exact match further ensures the accuracy particularly under the condition of manual intervention so as to prevent an error processing result caused by error intervention. The invention greatly enhances the logging treatment and the working efficiency of operating personnel of an interpretive system and provides technical support for the popularization of the project.

Description

technical field [0001] The invention belongs to the automatic identification and conversion technology of logging data formats in petroleum engineering, and relates to how to automatically and effectively identify the formats of various logging data formats in petroleum engineering, so as to quickly, accurately and automatically identify and convert these data, especially The invention relates to an automatic identification and conversion method of logging data format based on a feature library. Background technique [0002] In the specialty of petroleum engineering well logging, there are many types of well logging data and various storage formats, especially for field logging data, different instrument manufacturers have different data storage formats. According to statistics, there are as many as 100 kinds of logging data storage formats at home and abroad. [0003] These data often need to be converted into data format before processing and interpreting the logging data...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a method of automatic identification and conversion of logging data format based on a feature library that can automatically and accurately identify and complete the conversion, so as to solve the existing data conversion using manual identification and semi-intelligent fuzzy identification. The processing speed is slow, the efficiency is low, there are many manual interventions, the labor intensity is high, and the new data format is inconvenient.
