摘要: 根据盈亏平衡分析,结合天然气开发企业的特点,考虑了收入、成本费用、投资等经济参数,建立了天然气经济极限储量评价模型。利用模型,通过试算得到了在一定内部收益率的条件下,天然气价格、井深与经济极限储量之间的关系,同时探讨了不同内部收益率下的经济界限值。选择了某低渗透气田的10 个井区进行了实例分析,把这10 个井区根据经济效益的好坏分成了3 类,最后利用这10 个井区的计算结果进行回归,得到了含气面积与经济极限储量成幂指数关系的结论。因此,根据一个井区的井深和含气面积就可以粗略的估算经济极限产量和经济极限储量,为天然气经济效益储量评价方法提供了一种新思路。

Abstract: Considering the specific characters of gas development enterprise, this essay builds an evaluation model of the gas economic limit reserve boundaries with the break-even analysis, explores the relationship among the price of gas, well depth and the economic limit reserves when the IRR is fixed, and discusses the economic limit value varying with the IRR. The results of regression analysis of the benefits of ten low permeability gas fields prove that there is power exponent relationship between the gas-bearing areas and the economic limit reserves, then the economic limit production and economic limit reserves can be calculated, thus providing a new way for evaluation of the gas benefits reserves.

Key words:

low permeability, economy limit, reserves, production
