摘要:
在岩心描述及样品化验分析资料的基础上,结合测井解释成果,从储层微观特征、宏观分布,及非均质性等方面对重1井区齐古组二段储层进行了综合研究。研究发现齐古组二段储层岩性主要为细、中粒岩屑砂岩。储层岩石结构成熟度和成分成熟度均较低。储集空间主要是原生粒间孔、剩余粒间孔、粒内溶孔和少量粒间溶孔。孔隙度平均为27.2%,渗透率平均为3.042 × 10−6 µm2,大孔粗喉,属高孔高渗,孔隙结构较好的I类好储集层,并且非均质性较强。

Abstract: On the basis of core description and laboratory analysis, combined with the results of log interpreta-tion, we conduct a comprehensive study on reservoir microscopic characteristics, macroscopic dis-tribution, and heterogeneity of Middle Qigu Formation in Well Zhong 1 zone of Fengcheng field Op-eration District. The results show that lithology is mainly small, medium-grained lithic sandstone. The structure maturity and compositional maturity of reservoir rock are lower. The reservoir space mainly includes the remaining pores between grains, Intragranular dissolution pores and Intergra-nular dissolution pores. The average porosity is 27.2 percent and the average permeability is 3.042 × 10−6 µm2. The sandstone has good reservoir property which belongs to the high porosity and high permeability reservoirs with good reservoir properties and strong heterogeneity.
