摘　　要：依据边际气田地质油藏特征,通过多年的前期研究建立了一系列边际气田开发指标精准预测关键技术,包括气井产能评价新技术、稳产期快速确定技术、局部网格加密和组分模型技术、D因子关键参数求取技术,并以此为基础进行开发方案设计。研究结果表明,建立的边际气田开发指标精准预测技术具有较好的代表性和可靠性,保障和推动了丽水36-1、流花19-5、黄岩1-1等多个海上边际气田的高效开发,同时还成功推广应用于海外某低渗深水气田的前期研究。According to the geological reservoir characteristics of marginal gas fields,a series of key technologies of accurate prediction on marginal gas field development index have been set up through years of ODP research.The key indesed include new techniques of gas well productivity evaluation,rapid determination techniques of stable production period,local grid refinement and component model Technology,D factor acquisition techniques.Oilfield development plan is carried on based on this.The research results show that the established techniques are representative and reliable,which guarantee and promote Lishui 36-1 gas field,Liuhua 19-5 gas field,Huangyan 1-1 and other offshore marginal gas fields developed in efficient way,and also been successfully applied to the a low-permeability deep-water gas field overseas.
