长期以来，川西坳陷致密碎屑岩储层因其固有的非常规性，导致储层识别和产能预测较为困难。本文从该类储层的特征出发，根据川西坳陷７口井２４层生产测井解释成果，提出了致密储层产能预测的四种方法，丰富了储层识别的内涵，使储层识别与产能预测有机的联系起来。经矿场验证表明：对川西致密碎屑岩未知层段的天然气产量预测具有实用价值。
For a long time, because of its inherent unconventionality, the tight clastic rock reservoirs in the western Sichuan depression have led to difficulties in reservoir identification and productivity prediction. Based on the characteristics of such reservoirs, this paper presents four methods for predicting the productivity of tight reservoirs based on the interpretation of production logs of 24 wells in seven wells in the western Sichuan depression, enriches the connotation of reservoir identification, Productivity prediction organically linked. The field verification shows that it is of practical value to predict the natural gas production in the unknown interval of the tight clastic rocks in western Sichuan.
