鲁克沁三叠系稠油储层稠油粘度高在注水过程中储层易受稠油冷伤害;储层胶结程度弱,岩性疏松,胶结物泥质含量高、地层速敏、水敏伤害严重,常规酸化效果差、有效短;结合稠油储层的特点,开展了针对稠油储层的欠注机理和增注研究,有效解决了三叠系稠油储层增注难的问题。 The viscosity of heavy oil in the heavy oil reservoirs in the Ruqin Triassic heavy oil reservoirs is high. During the water flooding process, the reservoirs are vulnerable to heavy oil cold damage. The reservoir cementation degree is weak, lithology is loose, the clay content is high, Serious damage, poor conventional acidification effect and short effective time. Combining with the characteristics of heavy oil reservoirs, the research on under-injection mechanism and injection increase for heavy oil reservoirs has effectively solved the problem of difficult injection for heavy oil reservoirs in Triassic .
