摘要
通过对滨里海盆地让纳若尔油田2092和2399A两口井岩心资料与测井曲线的详细对比,同时考虑新老井之间资料的差异性,建立能够反映沉积相的测井相模式,并据此进行全区沉积微相的划分及沉积微相组合关系、空间展布特征和演化规律的研究。研究区发育了滩、滩间洼地、潟湖和潮汐通道4种沉积微相,储集层可划分为裂缝型、孔洞缝复合型、微裂缝-孔隙型、孔隙型4种类型。裂缝型储集层主要分布在滩间和潟湖环境中;孔洞缝复合型储集层主要发育于高能浅水环境下形成的滩微相中;微裂缝-孔隙型储集层也发育于高能滩环境,在潮汐通道中也有一定规模的发育;孔隙型储集层主要发育在相对低能的浅滩微相以及潮汐通道微相中。
By the observation under microscope on the cored sessions of the Well 2092 and the Well 2399A, four types of sedimentary microfacies including bank, howe between banks, lagoon and tide channel are identified. Based on the relation of sedimentary microfacies and logging curves, the characteristics of the corresponding logging are established. There are four types of reservoirs which are fractured reservoir, combination pore and crack reservoir, microcrack-pore reservoir and pore reservoir. The fractured reservoir is distributed between banks and in lagoons. The combination pore and crack reservoir is developed in the bank formed in high energy and in the shoal environment. The microcraek-pore reservoir is mainly distributed in the bank with high energy, and also developed in the tide channel. The pore reservoir is mainly developed in the shoal microfacies with relatively low energy and in tide channel microfacies.
