Chengong oil reservoir numerical simulation auxiliary history fitting software is based on ECLIPSE reservoir numerical simulator, which can realize historical fitting of reservoir historical data by adjusting oil reservoir parameters. the software realizes efficient stratified fitting, makes up for the deficiency of ECLIPSE software, and makes the historical fitting of oil and gas reservoirs more accurate and efficient.

We explore our software according to the actual situation of oil and gas fields in China, it is creative and solves the problem of stratifying section fitting difficulty which has plagued ECLIPSE software for a long time, realizes the high efficiency and fast stratifying section historical fitting, establishes the historical fitting platform based on error analysis orientation, achieves the integration and high efficiency of historical fitting from error analysis to adjustment and to the operation, improves the precision and efficiency of oil reservoir numerical simulation historical fitting, and greatly reduces the application threshold of oil reservoir numerical simulation software. The software is a powerful guarantee to achieve the goal of "accurate description", and has been applied in many blocks in Daqing oil and gas reservoir, which proves the stability and reliability of the software.

This software includes the historical fitting auxiliary tool, realizes the adjustment parameter process visualization, the data flow writing automation. realize arbitrary field data field superposition function, isoline display function, realize deposition microphase and permeability, pressure, saturation and other static and dynamic data field superposition display, bring great convenience to dynamic analysis work, at the same time have rich error display function, such as cyclone diagram, pie chart and so on. Automatic job management techniques for job scheduling, batch sending, parallel computing and error monitoring are created. Through well error analysis, layer error analysis and main control factor analysis, the rapid positioning and automatic parameter adjustment of error wells and layers are realized, and the fitting efficiency and fitting accuracy of oil and gas wells are improved. Based on the historical fitting adjustment method of Latin supercube and intelligent optimization algorithm, the automation degree of oil and gas reservoir historical fitting is improved.
