摘要
国际油气合作项目运营中经常需要进行单项(或部分)的经济评价,国际油公司最为通用的评价方法是独立评价法:将需要评价的油藏、生产井或者作业井,作为独立的对象来进行效益测算和评价.以国际石油项目某案例为基础,经过对同一对象采用独立评价法和系统增量法,发现两者的经济评价结果不一致.在寻找差异原因的过程中,发现了系统对局部影响,从而找到了造成差异的原因.独立评价法割裂了整体与局部的关联,忽视了大系统对局部的影响,扭曲经济评价结果,对科学投资决策具有较大的局限性;提出在国际油气项目运营过程中,应以系统增量法作为主要评价方法的观点.
Economic evaluation is a mandate for international oil companies,and the most frequently used method is Independent Evaluation,which takes certain reservoir,certain production well to be drilled,or certain well to be work-over,as the object of evaluation.This article,compared the difference from independent evaluation and system incremental evaluation on economic evaluation results,analyzed the cause of the difference,found the drawbacks of independent evaluation method,revealed that independent evaluation is misleading,and suggested system incremental evaluation method be applied for international oil companies during international operation.
