1993年7月阿莫科公司签订一项在波兰上西里西亚(Upper Silesian)煤田进行煤层气资源综合勘探评价的合同,并于1994年9月得到勘探许可。自此,阿莫科公司在波兰上西里西亚煤田打了7口取芯井和8口钻井,并进行了有关测试。 阿莫科公司在1994~1996年间所打钻孔证实了有关上西里西亚煤田煤炭资源的许多现有资料,并提供了有关煤层气生产的新资料。 对从阿莫科公司所打钻孔中收集的这些新地质资料的分析表明,上西里西亚煤田中的煤岩组分、煤质和甲烷等温吸附曲线变化很大。结合这部分资料,阿莫科公司正在对上西里西亚煤田中的煤层气饱和带和不同程度未饱和带中的煤层气资源进行更为精确的评估。该评估将对上西里西亚煤田中煤层气的经济储量及利用现有技术能够开采的潜在资源量做出明确的限定。
In July 1993, Amoco signed a contract for the comprehensive exploration and evaluation of CBM resources in the Upper Silesian coalfield in Poland and obtained an exploration license in September 1994. Since then, Amoco has fielded seven coring wells and eight wells in the upper Silesian coalfield in Poland and conducted the tests. Drilling by Amoco between 1994 and 1996 confirmed many of the available information on coal resources in Upper Silesian coalfields and provided new information on CBM production. Analysis of these new geological data collected from Amoco’s boreholes indicates that coal-rock components, coal and methane isotherms in the Upper Silesian coalfield vary greatly. Combined with this information, Amoco is conducting a more accurate assessment of the CBM resources in the coalbed methane saturation zone and in varying degrees of unsaturated zone in the Upper Silesian coalfield. The assessment will clearly define the economic reserves of CBM in the Upper Silesian coalfield and the potential amount of resources that can be extracted using existing technologies.
