摘要/Abstract

摘要： 初步分析了天然气田(藏)经济价值的基本概念和经济影响制约因子,进一步探讨了影响我国陆上天然气田(藏)内在经济价值的地质因素,得到以下基本推论:与开发投资直接相关的是储层深度和气藏的储盖层的岩性参数;对生产成本影响比较大的因素是自然地理因素和相应储层物性参数;对天然气产量影响比较大的因素是储层丰度、有效厚度、储层孔隙度、渗透率和气藏类型。在此基础上,以国家千米井深日产量评价标准为基准值,探讨了不同天然气富集区不同类别天然气藏的投资成本、价格因子以及经济价值判别的加权计算方法,得到了我国陆上主要天然气富集区可动用地质储量的经济判别标准,并对涩北1气田、长庆气田、克拉2气田、和田河气田、五百梯气田、东濮文23气田、千米桥气田等具有指标意义的中国陆上典型天然气田进行了分析。

Abstract: In this paper, the essential ideas and condition factors on economical value of onshore natural gas fields in China are analyzed preliminarily, and then the interrelated geological factors are discussed. Conclusions are deduced as follows. Firstly, the depth of reservoir and the sand parameters of natural gas fields have direct correlation with development investment. Secondly, geographical elements and corresponding material parameters of natural gas deposits exert greater effect on production cost. Thirdly, reservoir abundance, efficiency thickness, reservoir porosity, permeability, and types of onshore natural gas field have greater impact on gas production. On the basis of production per km-well per day, the economic production factor-weighed and computing formula of onshore natural gas fields in different capital, cost and price is approached, then the economic estimation criteria in different onshore natural gas fields are formulated, and some examples of typical onshore natural gas fields in China are analyzed, including the Sebei-1 gas field, the Changqing gas field, the Kela-2 gas field, the Hetianhe gas field, the Wubaiti gas field, the Wen-23 gas field and the Qianmiqiao gas field.

Key words: onshore China, natural gas field, geological factor, economic effect, weighed factor
