摘要
以野外实地观察和样品采集为基础,结合TOC测定实验、镜质组反射率实验、X射线衍射实验、扫描电镜实验、等温吸附实验等测试方法,对赣东北地区荷塘组页岩气藏的地质背景、生烃能力和储层条件进行了详细研究。结果表明,赣东北地区下寒武统荷塘组的页岩分布广泛,沉积厚度较大;有机质具有丰度高、类型好,成熟度较高的特点;矿物组成中脆性矿物含量高,储层微裂隙、孔隙发育较好;且储层吸附能力较强。根据以上特征,采用综合信息叠合法,初步确定磨盘山—灵山—上饶县一带为页岩气勘探有利区。
Based on field observation and sample collection,geologic background,hydrocarbon genetic capability and reservoir conditions of the Hetang Formation shale gas reservoir in the north- eastern Jiangxi area are studied in detail in combination with a number of testing methods such as experiments on TOC measurement,vitrinite reflectance,X ray diffraction,SEM and iso- thermal adsorption.It is suggested from the results that,the lower Cambrian Hetang Formation shale is distributed extensively with thick deposition in the north-eastern Jiangxi area,the organic matters have features of high abundance,good type and high maturity,minerals are composed of high content of brittle composition,micro- fractures and pores were well developed in the reservoir,and the reservoir has strong adsorptive capacity.According to above characteristics,by use of comprehensive information superposition method,the Mopanshan- Linshan- Shangrao zone is preliminarily defined as the favorable areas for shale gas exploration.
