溶蚀型次生孔隙是碎屑岩储集层的一种重要孔隙类型，溶蚀型次生孔隙的形成机制是石油地质学家很感兴趣的问题之一。本文运用吐哈盆地北部坳陷与民和盆地巴州坳陷碎屑岩储集层的分析测试资料，对研究区碎屑岩储集层溶蚀型次生孔隙发育状况的主要影响因素进行了分析，阐明了原生有效碎屑岩体的形成和保存受沉积作用和成岩作用的控制，在有效碎屑岩体的成岩过程中孔隙流体性质的显著变化是大规模形成溶蚀型次生孔隙的直接原因。
Eroded secondary pores are an important type of pores in clastic reservoirs. Formation mechanism of dissolved secondary pores is one of the most interesting problems for petroleum geologists. Based on the analysis and test data of clastic reservoirs in the northern Depression of Turpan-Hami basin and Bazhou depression in Minhe Basin, the paper analyzes the main influencing factors of the development of the dissolved secondary pore in the clastic reservoir in the study area , Clarified that the formation and preservation of primary effective clastic rock bodies are controlled by sedimentation and diagenesis. The significant change of pore fluid properties during the diagenesis of effective clastic rock bodies is the direct cause of the large-scale formation of dissolution-type secondary pores .
