Data Interface Design Of Universal Well Logging Platform And Implementation Of Concurrent Program

Logging software system is an important part of modern oil exploration.The logging process control,data logging and storage,curve display,processing and interpretation is all achieved by this system.Traditional logging software platform is unreasonable,imply functional,poor in cross-platform,poor scalability and does not support inter-well logging.So the traditional platform greatly limits the development of oil exploration.In order to adapt to the new logging technology and to improve the efficiency of oil exploration,we need to develop a comprehensive well logging software platform with independent intellectual property rights and has the functions of log management,data acquisition,processing and interpretation.During the software development,through the studying of the related issues of data acquisition,we propose a new concurrent logging data interface.This thesis briefly describes the history and development of oil exploration in recent years and introduction mainstream technologies of oil exploration.Upon the functional requirements analysis of the logging software platform,raised several issues in data interface part of the modern logging software development.By introducing and analyzing the overall architecture of logging system,we design a feasible concurrent logging data interface scheme which include three parts.The first part is a file parsing module.The second part is a real time data acquisition module supported cross-well logging.The third part is for data persistence,the design of database avoid the problem of data sharing.The data interface is developed by C++ language in Ubuntu system.In order to improve cross-platform feature,we use Qt integrated development environment for the development.Boost library was also used.The interface which has a certain value is more scientific and rational,able to adapt to the needs of the current logging system and has good scalability.In the end,the thesis summarizes the features of the proposed logging data interface and noted the current shortcomings,propose some improved approaches also.
