煤层气井产出水来源判别

Identify about Source of CBM Wells Produced Water

基于煤层气藏的地质理论认识,分析了煤层水的来源;并结合水化学三线图、离子浓度之间的相互关系与系统聚类逐步判别的方法,确定和建立了郑村区块主要含水层的水化学特征及判别函数。通过判别分析,识别了郑村区块煤层气井产出水来源并给与有效验证。

Based on theoretical understanding of coalbed methane reservoir, to analyze the sources of coal seam water, and combined with water chemistry trilinear diagram, the relationship between the plasma concentration and systemic clustering and stepwise discriminant method, to identify and establishment of a major aquifer water chemistry characteristics and discriminant function about Zhengcun block. By discriminant analysis, identify the Zhengcun block of CBM wells produced water sources and give effective verification.
