| 摘 要： | 构造煤的发育是产生煤粉的关键,破碎后煤岩会产生固有煤粉,而疏松的结构会使得煤岩更容易受钻井、压裂和排采等工程扰动影响,进而产生更多的煤粉。韩城区块经历多期构造,断裂构造造成的煤岩脆性变形、褶皱拉伸与挤压造成的煤岩韧性变形导致构造煤发育。以采集煤样宏观特征差异划分煤体结构类型,运用测井解释识别不同煤体结构类型煤,从纵向和横向上总结区块煤体结构分布规律,并揭示不同煤体结构类型对产出煤粉形态、浓度、粒度特征的影响。

| Abstract: | The development of tectonoclastic coal is the key to produce coal fines. Inherent coal fines will be produced after crushing, while the loose structures will make coal easier to be exposed to drilling, fracturing and drainage engineering impacts and produced more coal fines. The Hancheng block had experienced multistage faulted structures caused coal lithologic brittle deformation, folded extension and compression caused coal lithologic ductile deformation made tectonoclastic coal well developed. Taking macroscopic feature differences between coal samples partitioned coal texture types, using logging trace interpretation identified different coal texture types. Vertically and horizontally summarized coal texture distribution pattern, and revealed different coal texture type impacts on coal fines configuration, concentration, and particle size characteristics. |
