天然气储量的价值分级--模型设计与检验

目的 对天然气储量建立科学的价值分级和评估模型，从而科学地评价其储量资产的价值。方法采用综合评价方法，研究了天然气储量资源在勘探开发中，由于储量资源受地质条件、气田所处地理位置、交通运输条件和社会经济条件的不同影响，使各储量资源形成级差成本和级差收益。结果建立一种天然气储量的价值分级模型，并选取长庆气田和川西气田的26个区块作为样本对所建立模型进行检验。结论天然气储量的价值是以资源地质自然条件等级为主变量，同时受其所处自然地理条件和社会经济条件的影响。

A model designing and checking of value classification of natural gas reserves

Aim The purpose is to design a model of value classification of natural gas reserves, so that the evaluation of the gas reserves value will be performed scientifically. Methods The exploration and development of gas reserves is affected by geographical location as well as geological and natural conditions. Therefore gas reserves exploiting can gain differential benefit and pay differential cost. It is described describe how to evaluate the natural gas reserves using comprehensive assess method. Results For this purpose it is necessary to design a model of value classification of natural gas reserves. 26 reservoirs in Chuanxi and in Changqing Fields were selected as the actual checking objects. It is expected to provide a scientific evaluating method of a natural gas reserves value. Conclusion The classification of the gas reserves value mainly depends on the resource conditions, it also depends on the gas geographical location as well as social economy condition.
