摘　　要：认识致密油藏的生产特征及产量递减规律,有助于实现该类储量的有效动用和效益开发。通过分析红河92井区试采井的历史生产数据,明确不同生产阶段产量下降的递减规律,建立了该井区长8储层致密油藏产量的指数和双曲产量递减模型,并利用模型对生产井未来产量、递减率等指标进行了计算和预测。同时提出温和注水、体积压裂及“压-采”一体化等开发策略建议,为提高致密油藏的采收率和整体开发效益提供参考。It is helpful to realize the effective production and benefit development to tight reservoir of being aware of the production characteristics and production decline law of this kind of reserves.Based on the analysis of the historical production data of the production testing wells in Honghe 92 well block,the types of production decline in different production stages were defined.The exponential decline and hyperbolic decline model of Chang 8 tight reservoir are established,and the future production and decline rate of production wells are calculated and predicted by using the model.At the same time,some development strategies such as moderate water injection,volume fracturing and fracture-production integration are proposed to provide reference for increasing the recovery factor and overall development benefit of tight reservoir.
