查明小范围内煤储层渗透率分布特征为合理井网部署、科学预测产能提供重要保障。对阜康矿区西部煤岩层节理进行观测、统计和配套，获得了燕山晚期、喜山早期和喜山晚期3期构造应力场的主方向。结合构造运动反演法和煤层受力差异得出了研究区多期构造运动作用后14个块段内煤体结构及煤层的渗透率分布特征。结果表明：受多期构造运动作用影响，小范围内A2煤储层渗透率非均质性强，位于向斜核部扬起端埋深较浅处的煤层，煤体结构以碎裂–原生结构煤为主，渗透性最好；东北部风氧化带以深及南翼块段，煤层变形较弱，煤层渗透率中等；向斜核部埋深较深部位受多期构造运动影响较大，煤体变形较严重，以碎粒–糜棱煤为主，渗透性差；南部及西北部，受多期构造运动作用影响最大，煤层渗透性最差。钻井取心及渗透率实测资料验证了预测结果的准确性，此研究方法为多期构造影响下的小范围内煤层渗透率预测提供了一种思路和借鉴。
Identifying the distribution characteristics of coal reservoir permeability in a small area provides an important guarantee for rational well pattern deployment and scientific prediction of production capacity. The main direction of the tectonic stress field in late Yanshan, early Himalayan period and the third stage of the Himalayan period was obtained by observing, counting and matching the coal seam joints in the west of Fukang Mining Area. Based on the difference between tectonic inversion method and coal seam stress, the coal body structure and coalbed permeability distribution in 14 blocks after multi-period tectonic movement in the study area are obtained. The results show that, due to the multi-stage tectonic movement, the A2 coal reservoir has a small heterogeneity in permeability and is located at the shallow burying depth at the rising core of the syncline. The structural coal is the main type and the permeability is the best. The northeastern wind oxidation zone is deep and the south wing block, the coal seam is weakly deformed and the permeability of the coal seam is medium. The deeper part of the syncline core is more affected by the multi-period tectonic movement, The deformation of the coal body is more serious, which is dominated by granulite - mylonitization coal, and the permeability is poor. The southern and northwestern parts of the coal are most affected by the multistage tectonic movement and the coal seam permeability is the worst. The measured coring and permeability data confirm the accuracy of the prediction results. This research method provides a way of thinking and prediction for the prediction of coal seam permeability under the influence of multi-period structures.
