泌阳凹陷陆相页岩油重点井解剖与对比

Anatomy and correlation of key wells of continental shale oil in Biyang Depression

泌页HF1井与泌页2HF井同为部署于泌阳凹陷的页岩油水平井,目的层同为5号页岩层,两口井产量呈现出递减先快后慢的特征,但是稳定后产油量差异较大,泌页2HF井的日产油量和累计产油量明显高于泌页HF1井。为明确两口井产量影响差异原因,从岩性、岩相、有机质丰度、热演化程度、孔隙度、微裂缝发育程度、粘土矿物含量、岩石力学参数等方面,开展两口页岩油井的解剖及对比分析工作。

in view of the great difference in oil production between two shale oil horizontal wells in Biyang sag,Biye HF1 and Biye 2HF,detailed anatomy and comparison are carried out from the aspects of lithology,lithofacies,organic matter abundance,thermal evolution degree,porosity,microfracture development degree,clay mineral content and rock mechanical parameters.
