涪陵一期页岩气水平井分段压裂效果分析

Analysis of Staged Fracturing Effect of the 1st Period Shale Gas Horizontal Wells in Fuling Area

页岩气水平井压裂改造的好坏是影响压后产能的重要因素。通过对储层特征进行剖析,认识到涪陵一期页岩气储层有利于体积压裂改造;从地质储量、天然裂缝发育、改造方式、各项施工参数等方面进一步剖析一期施工井分段压裂效果,得到了相应的结论,为一期后期、二期井位的布井和试气等提供参考。

Fracturing result of a shale gas horizontal well is an important factor to influence after-fracturing capacity. The analysis of reservoir characteristics learns that the 1st period shale gas reservoir in Fuling area is in favor of volume fracturing. Further analysis of staged fracturing effect of the 1st period operation wells from such aspects as geological reserves, natural fracture development, fracturing mode and all operation parameters acquires the corresponding conclusion, thus providing a reference for the location of the 1st later period and 2nd period wells and their gas testing.
