摘要
本文根据煤层气资源有利富集区勘探阶段的地质勘探和基本的钻井试气数据资料,进行含气区的储量计算和开发生产数值模拟,并在此基础上对其进行基本的技术经济指标和经济极限的测算,然后对有关勘探开发方案进行经济决策分析,在一定程度上解决了煤层气勘探阶段因缺乏实际的生产资料而难以进行勘探投资经济评价的困难。根据我们所建立的这种勘探开发决策评价模型,对山西某煤层气田进行了基本的勘探开发经济决策研究。
Based on the geological exploration and basic drilling gas-testing data in the exploration stage in the favorable coalbed gas enrichment areas, this paper carries out the numerical modeling for reserve calculation and production. On this basis, the basic techno- economic indexes and economic limit are calculated, then, the economic decision analysis is estimated for some exploration and development schemes. It, to some extent, overcomes some difficulties in economic evaluation for exploration investment in the coalbed gas exploration stage due to lack of practical data. Based on this decision and evaluation model for exploration and development, we carry out a basic economic decision study on the exploration and development for some coalbed gas fields in Shanxi province.
