Based on the research results in gas field developmment, this paper summarized the development of optimization at domestic and foreign from two aspects: Infilled well deployment, piped network design, pointed out the difficulties and development directions of each part, and provided reference for gas field mining. The analysis points out that there are some difficulties in algorithmic improvement and well pattern density identification in the deployment of infill wells. Further research is needed in the deployment direction of shale gas field infill wells. Model establishment and algorithm improvement are the difficulties in pipe network research, further study of three⁃dimensional terrain relief layout analysis is required.
