涪陵页岩气田凤来区块压裂效果分析

Analysis of Fracturing Effect in Fenglai Block of Fuling Shale Gas Field

参考统计涪陵页岩气田凤来-东胜区块已实施邻井相关参数,结合区域地质特征,对比相邻区域和施工特征,分析南-北区、主体工艺和泵注工艺差异。以高产井焦页E-3HF井突破为主线,结合区域天然裂缝、宏观应力、埋深等地质影响特征,从主体压裂工艺、参数优化及泵注程序等方面开展效果对比分析,并提出下步优化建议。

With reference to the offset well parameters implemented in Fenglai-Dongsheng Block of Fuling Shale Gas Field,and considering the regional geological characteristics,a comparative analysis is conducted on the differences in the southern and northern block,main processes,and pumping techniques.Taking the breakthrough of the high-production well Jiaoye E-3HF as the main focus,combined with geological influences such as regional natural fractures,macro stress,and burial depth,a comparative analysis of the effects is carried out in terms of the main fracturing process,parameter optimization,and pumping schedules.Further optimization suggestions are proposed for the subsequent steps.
