涪陵焦石坝地区页岩气赋存特征定量表征及其主控因素
|
摘要
为解决页岩气开发过程中,单井实测含气量与测试产量存在明显矛盾的问题,系统开展了测井解释含气量和实测含气量的对比研究,认为在焦石坝地区使用测井解释含气量来代替实测含气量是可行的.在详细对比有机质丰度、有机质成熟度、孔隙结构、地层温度和压力等对页岩含气量影响的基础上,明确孔隙结构是控制页岩气赋存特征的主要因素.对涪陵焦石坝地区而言,由于纵向有机质丰度差异而带来的孔径和孔隙度等孔隙结构的不同是导致上、下部气层赋存状态变化的主要原因.对中国南方海相页岩开发选区评价而言,在今后的开发选区过程中,应更加注重开展页岩孔隙结构对赋存状态的影响研究.
In order to solve the problem of obvious contradiction between measured gas content and test yield in single well during shale gas development,a systematic comparative study of log interpretation gas content and measured gas content is carried out.It is considered that it is feasible to use log interpretation gas content to replace measured gas content in Jiaoshiba area.On the basis of detailed comparison of the effects of organic matter abundance,organic matter maturity,pore structure,formation temperature and pressure on shale gas content,it is clear that pore structure is the main factor controlling the occurrence characteristics of shale gas.The difference of pore size and porosity caused by the difference of vertical organic matter abundance is the main reason for the change of occurrence state of upper and lower gas reservoirs in Jiaoshiba area,Fuling.For the evaluation of marine shale development constituencies in southern China,more attention should be paid to the study of the influence of shale pore structure on the occurrence state in the optimization of favorable areas for future development.
