中国陆上天然气资源的经济效用影响因素研究(英文)

本文研究了中国陆上天然气经济效用的地质及相关影响因素。主要研究结论如下:天然气勘探开发成本主要与气田(藏)的深度及储盖层的岩性参数相关,开采成本主要受自然地理因素以及相应储层物性参数影响,而气田(藏)丰度、有效厚度、孔隙度、渗透率和气藏类型是影响天然气产量的主要因素。基于上述研究结论,建立了针对投资成本、价格因素和气田经济价值的千米井深日产量计算公式和区域判断标准。根据判别标准,本文分析了中国不同区域且具有指标意义的天然气田(藏)的经济效用,并针对中国天然气产业经济发展提出了相应的结论和建议。

Regional Economic Factors for Weighted Evaluation of Onshore Natural Gas in China

This paper analyzed the essential concepts of the effective geological factors of economic value for onshore natural gas regions in China and the interrelated factors were researched systematically.The main issues that have been discussed are as follows: the cost of development and investment more related to the depth of reservoir and the sand parameters of overlying formation of natural gas region; production cost is mostly affected by natural geographical elements and corresponding material parameters of the deposit; the reservoir abundance,efficiency thickness,porosity of reservoir,permeability and the type of the gas reserve are the main affecting factors of production.Based on these researches,the factorweighted computing formula for investment costs,price factors and the discrimination for economic value of onshore natural gas fields were studied.Seven examples of typical onshore natural gas fields in western,middle and eastern China were analyzed with criteria for the geological reserves that have been developed and several suggestions for the sustainable development of Chinese natural gas industry were presented.
