大庆西部外围油田外扩井开发经济评价及敏感性分析

Economic evaluation of development and sensitivity analysis

为做好后备资源的优选评价工作 ,应用技术经济学原理及大庆外围油井单井临界经济产量计算公式 ,对外围油田的外扩井开发进行了经济可行性分析 ,确定出经济界限值 ,计算了基本评价指标 .评价结果表明 :龙虎泡油田南块、敖古拉油田塔 3井区、高西油田外扩井都具备开发条件 ,龙南油田古 4 1,古 38井区不具备开发条件 .选择了售价、投资、操作费 3个因素做了敏感性分析 ,其中售价和操作费对内部收益率指标的影响较大 .

Economic feasibility analysis is made for the development of the outstep wells in the peripheral fields by means of technical and economic principle and the critical economic flow rate of the single well in the peripheral well zones; the economic limit values are established and the basic evaluation indicators are calculated. Results show that three of the fields satisfy the conditions for development, and two of the fields do not. Three factors, sale prices, investment and operation cost, are selected for the sensitivity analysis. Results show that sale prices and operation cost have bigger effect on the internal benefit indicators.
