鄂尔多斯盆地A区块长6₃砂组为超低渗储层，常规开采难度大，目前普遍采用水平井压裂的开发方式。针对超低渗储层物性特征，利用地质力学模型和压裂模拟软件，结合嵌入式离散裂缝方法对长6₃砂组压裂模拟产生的人工裂缝进行表征，并基于此开展数值模拟研究。通过这一整合流程，实现水平井复杂压裂的一体化模拟，提高水平井开发的效率。结果表明：嵌入式离散裂缝方法可以将压裂与数值模拟有效结合，实现水平井从压裂到数值模拟一体化的流程；采用定产油的生产方式进行历史拟合，验证数值模型的准确性。通过不断调整相关参数优化模型，使其更加符合井组生产实际情况，有利于后续开发方案调整和生产预测。

The Chang 6₃ sand formation in Block A of Ordos Basin is an ultra-low permeability reservoir, which is difficult to be conventionally exploited. At present, horizontal well fracturing is widely used for development. According to the physical characteristics of ultra-low permeability reservoir, the geomechanical model and fracturing simulation software, combined with embedded discrete fracture method were used to characterize the artificial fractures generated by fracturing simulation of Chang 6₃ sand formation, and carried out numerical simulation research based on this. Through this integrated process, the integrated simulation of complex fracturing of horizontal wells were realized, and the efficiency of horizontal well development was improved. The results show that the embedded discrete fracture method can effectively combine fracturing and numerical simulation, and realize the integrated flow from fracturing to numerical simulation of horizontal wells. The accuracy of the numerical model was verified by the historical fitting of the production mode of fixed oil production. By adjusting the relevant parameters to optimize the model, it is more in line with the actual production situation of the well group, which is conducive to the subsequent development plan adjustment and production forecast.
