Problems solved by technology

For users of well logging software, this process requires the user to master the computer programming language and be familiar with the code development process. Even for users with well logging professional background, it is a relatively cumbersome and complicated problem
On the other hand, the model integrated into the software and the software itself are not an organic whole, and cannot transmit data and share information with other functional modules, so it is also inconvenient to use

Abstract

The present invention discloses an oil well logging model processing method and system based on formula analysis. The method comprises: obtaining an oil well logging formula; analyzing the oil well logging formula, and extracting formula parameters and formula variables; acquiring external attribute data at least comprising a formula name, an application scope, and formula parameter dimension; and according to the oil well logging formula, the formula parameters, the formula variables, and the external attribute data, generating an oil well logging model and storing the model in a model library. According to the oil well logging model processing method and system disclosed by the present invention, a creation process for establishing the model of the oil well logging formula can be simplified, and the established oil well logging model can improve convenience and practicality of explanation of well logging processing.

Description

technical field [0001] The invention relates to the field of petroleum logging processing and interpretation software, in particular to a method and system for processing petroleum logging models based on formula analysis. Background technique [0002] Well logging processing and interpretation software is a very important technical tool in petroleum well logging processing and interpretation. Users rely on it to perform operations such as well logging data preprocessing, processing, interpretation, analysis and evaluation. When the logging software processes and interprets the logging data, many parameter calculation models are used. Each model is calculated according to a calculation formula and based on one or several logging curves, such as calculating the saturation of oil and gas saturation. Calculation model, acoustic wave model or density model for calculating formation porosity, etc. For different oilfield blocks and different reservoirs, there are different calcul...
