摘　　要：海外油气项目涵盖陆上常规、陆上非常规、中深海、滩浅海、液化天然气等多种资源类型,不同油气项目所在资源国油气生产财税制度不同,主要的3种财税合同为矿税制合同、产量分成合同和服务合同。基于财税合同的差异,探索建立不同财税制度下单井关停界限产量的数学公式,测算不同价格情景下老井关停井界限的变化情况,并分析不同价格区间同口单井在不同财税制度下有效益生产时间的长短。以典型井为例,当油价高于60美元/桶时,产量分成合同最优,低于60美元/桶时,固定报酬的服务合同优势明显,该结论为海外油气资源生产经营提供经济依据和分析参考。Overseas oil and gas projects cover a variety of resource types,such as onshore,mid-deep offshore,shallow offshore,and liquefied natural gas.Different projects are in different resource countries with different fiscal terms for oil and gas production.The 3 main types of fiscal contracts are concessions,production-sharing,and service contracts.Based on the differences in contracts,mathematical formulas for the yield boundary of shut-in single wells under different fiscal terms are established.This paper further calculates the changes in boundary yields of shut-in single-well under different price scenarios and analyzes the length of the profitable production time of the same single well under different fiscal terms within different price ranges.Taking a typical well as an example,when the oil price is above US$60/barrel,the production sharing contract is optimal,and when the oil price is below US$60/barrel,the advantage of fixed remuneration of service contracts is obvious.The conclusion provides an economic analytical reference for the production and operation of overseas oil and gas resources.
