摘要
对某大型油田一级区块的成本效益进行评价,以为油田下一步产能部署投入提供参考依据。基于级差地租理论,着重考虑油藏地质条件和油田勘探开发阶段等因素对成本效益产生的差异化影响,分别从勘探开发投资成本和开采成本2个层面构建油田区块成本效益评价模型。在此基础上,运用层次分析法给出了该油田25个一级区块的成本等级值综合序列,并结合油田所处的发展阶段,运用聚类分析法将这些区块划分为高效、中效、低效和无效4个等级。通过对低效及无效油田区块效益低下原因的分析,认为加强新增投资区块优选、按照效益最大原则倒推产量部署和加强技术攻关是提升区块成本效益的主要途径。
This paper evaluates the cost benefits of a large oil field＇s level 1 blocks so as to provide references for extracting oil. Based on differential rent theory, this paper establishes a cost benefits evaluation model of oil field block from exploration cost and extraction cost in consideration of the differential effect of reservoir geology and exploration stage on cost benefits. AHP is employed to rank their cost levels among 25 blocks, which are classified into four levels, highly effective, intermedium effective, low effective and no effective by means of clustering analysis. Causes are given for the low effective and no effective blocks. This paper presents approaches to increasing cost benefits in optimizing blocks, allocating production Dlanning from maximizing benefits nrineiBle and intensifying technical research.
