准噶尔盆地西北缘克-百地区侏罗系储集层特征及主控因素分析
Characteristics and main controlling factors of the Jurassic reservoir in Ke-Bai area, northwestern margin of Junggar Basin
摘要
Abstract
Based on large number of thin-sections and casting thin-section observations, mercury analysis and core observations,the Jurassic reservoir characteristics of Ke-Bai area in northwestern margin of Junggar Basin have been systematically studied. The lithology characteristics of the Jurassic reservoir are that near the provenance, composition maturity is low, less pore-filling contents, the cementation is characterized by carbonate-cementation,rich in plastic clastic, the sandstones are well sorted and sub-angular,textural maturity is moderate. As the burial depth of Jurassic reservoir is shallower, diagenesis is simple.Storage space is characterized by primary pores. Influenced by faults, secondary pore is well developed. Compared to sandstone, conglomerate has more intragranular dissolution pores.The characteristics of pore texture are controlled by the lithology characteristics of reservoir.Pore texture of reservoir can be divided into three types: well sorted and bold skewness, better sorted and slightly fine skewness,moderate sorted and fine skewness.The main controlling factors of the Jurassic reservoir include grain size, compaction and dissolution. Among them, compaction determines reservoir quality.关键词
