影响油气勘探经济评价的主控因素

Factors affecting economic evaluation of oil and gas exploration

在油气勘探经济评价影响因素的综合分析基础上,对松辽盆地北部某一深层火山岩圈闭天然气勘探经济评价的主控因素进行了研究,分析了油气价格、油气产出量、行业基准收益率、经营成本、投资额5个要素对经济评价指标净现值、内部收益率和投资回收期的影响程度,指出油气价格对净现值、内部收益率和投资回收期的影响程度最大,其次是油气产出量、行业基准收益率、开采成本和投资额,为实际勘探目标决策提供了参考。

Based on comprehensive analysis of the factors affecting economic evaluation of oil and gas exploration, this paper studies the controlling factors of economic evaluation of gas exploration in a deep volcanic trap in the north of Songliao Basin, analyzes the influence of oil/ gas price,recoverable reserve,basic rate of return of the industry, operating costs, and capital investment on economic evaluation indices like net present value, internal rate of return and payback period . It is concluded that oil/gas price has the biggest effect on NPV, IRR and Tp, and then are recoverable reserve,basic rate of return of the industry, operating costs, and capital investment. This study provides a reference to decision-making in oil and gas exploration.
