油气开发经济评价的不同特点和方法

The Different Features of and Methods for the Economic Evaluation on Oil/Gas Development

由于石油和天然气在赋存状态、销售方式和销售途径等方面存在差异,二者的经济评价方法不尽相同。根据"有无"对比原理,石油开发项目具有"横向"的特点,经济评价的实质是"有项目"和"无项目"项目的对比,评价的投入产出范围一致,评价的对象是增量投资和增量产出;天然气开发项目具有"纵向"的特点,经济评价的实质是对"有项目"的评价,评价的投入产出范围可能存在差异,评价的对象是增量投资和累计产出。

Because of the differences existing in the occurrence state, sales method and marketing channel of the oil and the gas, the method for the economic evaluation on the oil and the gas is not quite similar. According to the with and without comparison method, the oil development project has＂lateral＂feature, and the substance of the economic evaluation is the comparison of＂with the project＂and＂without the project＂, the input-output scope of the evaluation is consistent, the objects of evaluation are incremental investment and incremental output; the gas development project has ＂longitudinal＂ feature, and the substance of the economic evaluation is the evaluation of ＂with the project＂, there probably are the differences in the input-output scope, the objects of evaluation are incremental investment and accumulated output.
