世界石油库存量加速下降

据路透社伦敦２月１１日电，国际能源机构（ＩＥＡ）在当日出版的一期《石油市场月报》中指出，全球工业化国家的石油库存去年底大幅度下降，目前下降的速度在进一步加快。据统计，经合组织国家（ＯＥＣＤ）去年１２月份的石油商业性库存减少达２７０万桶／日，降幅创１９９４年２月以来之最。这使１２月份该组织国家的石油商业性库存总量降到了２５．２８亿桶，比１９９６年底因严冬和石油公司削减成本而造成的低库存水平还少２３００万桶。美国能源信息署（ＥＩＡ）的统计数据也显示，今年１月份ＯＥＣＤ的石油库存下降水平将超过去年第四…

Determination Approach of Development Indexes in A Condensate Gas Reservoir at Constand Volume

By linking equation of geologic equilibrium in a condensate gas reservoir,exponential equation of gas well productivity with gas reservoir's fluid characteristics,prediction of development indexes of a condensate gas reservoir at constant volume has been made, establishing individual behavior process of pressure, yielded dry gas, condensate oil as well as each pseudo-component, and determining stable rate period and declining ended time during production of a condensate gas field. Field application showed that this method is simple and reliable, and can be effectively used for comprehensive evaluation, progress selection and macroscopic decision of a condensate gas field development.
