摘　　要：为规避浅海油田投资的高风险,将经济评价方法和产能建设投资方法相结合,建立了浅海油田开发单井产能经济界限模型和百万吨产能投资模型,研究了单井日产经济界限、单井累产经济界限、单井控制储量经济界限与油价和井深的变化关系,以及百万吨产能投资大小与单井日产和井深的关系.结果表明:井深不变时,单井日产经济界限、单井累产经济界限以及单井控制储量经济界限与油价成反相关的关系;油价不变时,井深与单井日产经济界限、单井累产经济界限以及单井控制储量经济界限成正相关的关系.井深不变时,百万吨产能投资与单井日产量成反相关的关系;百万吨产能投资不变时,井深与单井日产量成正相关的关系.In order to avoid the investment risk of offshore oilfield,an economic limitation model of single well productivity and a investment model of 1Mt/a productivity oilfield in offshore oilfield development are established by combing economic assessment methods and productivity investment methods,and the relationships between the daily output economic limitation,the cumulative output economic limitation and the control reserves economic limitation of single-well and the price of crude oil and the depth of oil wells and the relationship between the investment of 1Mt/a productivity oilfield and the daily output of single-well and the depth of oil wells are presented.It is shown that when the depth of oil wells is unchanged,the daily output economic limitation,the cumulative output economic limitation and the control reserves economic limitation of single-well are negatively related to the price of crude oil,and when the price of crude oil is unchanged,they are positively related to the depth of oil wells;when the depth of oil wells is unchanged,the investment of 1Mt/a productivity oilfield is negatively related to the daily output of single-well,and when the investment of 1Mt/a productivity oilfield is unchanged,the depth of oil wells is positively related to the daily output of single well.
