Abstract: 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.

摘要： 基于气田开发领域的研究成果，分别从加密井部署、管网设计两部分综述了国内外优化方案的发展，并指出了各部分的难点及发展方向，为气田开采提供借鉴。分析指出了加密井部署中存在算法改进和井网密度确定的难点，页岩气田加密井部署方案尚需开展进一步研究，管网优化模型建立和算法改进是研究的难点，三维地形起伏布局分析需开展深入研究。
