摘要

页岩储层纳米级孔喉发育,属于典型的特低孔特低渗储层,且纵向非均质性强,难以获得自然产能。通过产量影响因素分析,认为储层高含气丰度和有效的压裂改造是页岩气井获得高产的两个基本条件。基于涪陵页岩气开发实践,选取影响页岩含气丰度和可压性的地质因素作为页岩气开发选区地质评价的关键参数,建立2大类12项页岩气开发选区综合地质评价参数体系,并初步确定了开发选区标准,为国内页岩气开发选区地质综合评价提供借鉴。
        Nanoscale pore throats are developed in shale reservoir which belongs to typical ultra-low pore and permeable reservoir and has a strong vertical anisotropism, hard to acquire natural capacity. Analysis of yield influencing factors believes that high gas abundance and effective fracturing reform are the two basic conditions for shale gas wells to give a higher yield. On the basis of Fuling shale gas development practice, high gas abundance and compressible geological factors are selected as the key parameters for geological evaluation on shale gas development district selection. The evaluation parameter system(2 large categories including 12 items) is established and the development district selection standard takes initial shape, providing a reference for comprehensive geological evaluation on inland shale gas development district selection.
