Abstract:

The Devonian sequences are distributed in Tuoputai industrial zone in Tahe area, where the sand bodies are in general spreading nearly in SN, thick in NW and thin in SE. The reservoir is characterized by primary granular pores, granular corrosion pores, intergranular corrosion pores, with a few other pores. The reservoir channel sorting belongs to mediate to poor. Most channels are thin. Donghe sandstone reservoir develops compaction, cementation and corrosion. According to reservoir features and evaluation codes, the reservoir is classified into three types, which have been evaluated individually.

Key words:

Tahe; Tuoputai; Devonian system; reservoir

摘要：

塔河地区泥盆系地层分布在托浦台工区，研究区砂体总体上近南北向展布，北西厚南东薄。储层的储集空间以原生粒间孔隙、粒间溶蚀孔隙、粒内溶蚀孔隙等次生孔隙为主，其他类型孔隙较少。储层喉道分选中等偏差，喉道多为细喉型。本区东河砂岩储层主要发育压实作用、胶结作用、溶蚀作用等成岩作用类型。根据储层物性以及储层评价标准，我们将该区储层划分为3类，并对其进行了分类评价。
