Abstract:

System reconstructability analysis is a widely developing field of general system theory. It provides a foundation for solving the problems of complex and heterogeneous systems with continuously and rapidly changing qualitative and mass relationship, as well as structural relationship, which are difficult to describe in the form of mathematic analysis. System reconstructability analysis consists mainly of factor analysis, program evaluation and expert opinions. Evaluation of hydrocarbon prospective areas is complicated with many uncertainties, due to the combined impacts of natural factors, such as geologic conditions, geographic environment and resource potential, as well as policy, law and regulation, investment climate and market environment. Evaluation made with a single index would have large eventuality and instability. A system model for evaluation of hydrocarbon prospective areas has been developed by applying system reconstructability analysis. It preliminarily solves the problem met in evaluation, such as the lack of data set and strong non-linearity.

Key words: prospect generation, prospective evaluation, system reconstructability analysis, composite integration, complexity
