塔里木盆地石油与天然气储量经济价值评估方法研究

Research on The Economic Evaluating Method of Oil and Natural Gas in Tarim Basin

储量经济价值的评估方法通过产量预测来计算销售收入;通过成本估算和销售收入来计算年净现金流;将废弃(年净现金流为零)前历年净现金流贴现并求和得到累积净现值,此值即为从评价起点起算的可采储量的经济价值。其关键是预测油田产量、计算销售收入、计算成本和费用以及计算现金流。影响储量经济价值的因素有:储量发现成本、单位产能建设投资、生产经营成本、商品销售价格、税费率。

The economic evaluating method of reserves is calculating sales revevue by forecasting production,calculating annual net cash flow on the basis of cost estimate and sales revenue,calculating accumulated net value which is the eco- nomic values of recoverable reserves from the point of evalua- tion by discounting and adding of net cash flows over the year before discarding(annual net cash flow is zero).The key is forecasting production of oilfield,calculating sales revenue,costs and cash flow.Factors influencing reserves economic evaluation are reserves discovery costs,investment in producing capability, operating costs,sales price and tax rate.
