摘　　要：油气企业对单井效益评价方法中收益与成本指标的应用还存在着模糊的认识。为此,在介绍单井效益评价方法中的收益与成本指标的基础上,将其运用于某油气田的单井效益评价,并与单井效益评价中的日产油气量和综合含水率指标运用的结果进行了对比分析。结果表明,只依据日产油气量或综合含水率指标对单井效益进行评价,可能导致油气田管理效率不高,甚至可能得出错误的结论。分析认为,单井效益评价中应采用收益与成本指标来确定油气井是否有效;对有效井的效益评价,应综合考虑企业的内外环境来选择使用相应的效益评价方法,或者综合应用多种方法。Up till now little knowledge was recognized by oil and gas companies on profit and cost evaluation indexes on a single well and their application. Hereby based on the brief introduction about the profit and cost in the profit evaluation method on a single well, this study used it at a certain oil and gas field, and carried out comparative analysis on the differences between profit + cost and the daily oil and gas production + composite water cut. This study result showed that if a single well profit was judged only by the daily oil and gas production and composite water cut, a wrong conclusion might mislead the operators or managers in the end; and the indexes of profit and cost could be reasonable to evaluate on a single well profit and so as to judge if this well was cost-efficient or not, if cost-efficient enough a corresponding evaluation method or multiple methods should be taken fully into consideration under both internal and external environment of an individual oil and gas company.
