Taiyuan formation is the main exploration strata in Ordos Basin, and coals are widely developed. Due to the interference of strong reflection of coals, we cannot completely identify the effective reservoir information of coal-bearing reservoir on seismic data. Previous researchers have studied the reservoir by stripping or weakening the strong reflection, but it is difficult to determine the effectiveness of the remaining reflection seismic data. In this paper, through the establishment of 2D forward model of coal-bearing strata, the corresponding geophysical characteristics of different reflection types of coal-bearing strata are analyzed, and then the favorable sedimentary facies zones for reservoir development are predicted. On this basis, combined with seismic properties, the coal-bearing reservoir is quantitatively characterized by seismic inversion. The above research shows that the Taiyuan formation in LS block of Ordos Basin is affected by coals and forms three or two peaks in different locations. The reservoir plane sedimentary facies zone is effectively characterized by seismic reflection structure. Based on the characteristics of sedimentary facies belt and petrophysical analysis, the reservoir is semi quantitatively characterized by attribute analysis and waveform indication, and quantitatively characterized by pre stack geostatistical inversion. Based on the forward analysis of coal measure strata, this technology characterizes the reservoir facies belt through seismic reflection characteristics, and describes coal measure reservoirs step by step. It effectively guides the exploration of LS block in Ordos Basin, and has achieved good practical application effect.

通过开孔板压缩试验和建立的参数化多尺度有限元模型,获得微细(φ0.11 mm)金属Z-pin植入体积分数和排布方式对开孔板压缩力学性能和失效行为的影响规律.采用离散实体单元代表Z-pin,选用3D Hashin失效准则判断面内起始损伤,可以有效地模拟结构失效过程中扭结现象的不稳定扩展.结果表明,所有加Z-pin开孔板的压缩强度均低于无Z-pin试样.随着Z-pin植入体积分数的增加,Z-pin与层合板之间的桥联作用增强,加Z-pin开孔层合板压缩强度增加,开孔周围分层损伤区域受到抑制,损伤区域面积最高减小了67%.在相同的体积分数下,Z-pin排布变化对开孔板压缩强度没有显著影响.加Z-pin开孔板有限元模型的模拟结果与试验结果之间的最大相对误差为8.6%.
