摘要
确定天然气储量最低经济规模(即相对于勘探投资要求探明天然气资源的最低数量)是提高天然气勘探投资决策水平的需要,也是勘探投资决策者迫切要求解决的问题。根据投资净现值为零时投资者只获得最低期望收益的原理,在分析影响天然气投资现金流量各因素的基础上,将与储量相关的参数表示为储量规模的函数,并以储量规模作为变量通过令净现值为零得到确定天然气最低经济储量规模的数学模型,从而为天然气勘探投资提供一种决策方法。
Determining the minimum economic resource for gas exploration (i. e. the minimum proven gas in place obtained by the exploration investment) is the requirement to improve the decision-making level of gas exploration investment and the problem for the decision-maker of exploration investment to solve urgently. According to the principle i. e. the investor obtains only the expected minimum benefit when NPV is zero, based on the analysis of various factors effecting the cash flow of gas investment, the parameters related with the reserves are expressed as the function of reserve scale, and the mathematical model is developed to determine the gas minimum economic resources taking the resources as a variable and given NPV is zero, which provides a decision-making method for gas exploration investment.
