| 摘 要： | 针对致密性储层裂缝中油气井产能预测准确度较低、难以满足实际工程需求的问题，基于对储层裂缝流体渗流过程的分析，提出一种储层裂缝定量预测模型。该模型针对无限水平储层和有限水平储层不同地质特点分别推导出水平井产能计算预测公式，并在预测公式中有机结合了储层径向流、裂缝线性流和裂缝径向流的流量计算。经过试验验证，储层裂缝定量预测模型的预测产量误差为13%，符合产能预测的要求。

| Abstract: | In allusion to the problem of oil and gas well productivity prediction accuracy was low and it was difficult to meet the needs of actual engineering in the crack of tight reservoir.A model was based on the analysis of seepage process of reservoir fracture fluid.The model in infinite reservoir and limited level of reservoir capacity calculation of horizontal well was deduced on the different geological features prediction formula，and the organic combination of the reservoir in the prediction formula of the radial flow of cracks，fracture linear flow and radial flow calculation.After test verification，the forecast output error of the model proposed was 13%，which was in line with the requirement of production capacity prediction. |
