Analysis and Software Development of LiMin's Production Decreasing Method

By employing VB.net as our development tool, we have developed the production decreasing analysis software based on LiMin's production decreasing fitting method. The software is divided into three major modules: decreasing parameters determination, historical production fitting and forecasting future production. Corre-spondingly, our software development is completed in the following three steps: firstly, real time is converted to standardized time; secondly, linear regression method is used to determine the decreasing parameters of the initial decreasing production output “qi” and the initial decreasing rate “Di”; thirdly, the historical production is fitted and future production is predicted on the basis of Arps method.
