冷家油田沙三段储层非均质类型分析

Analysis of Heterogeneous Type of Reservoir in Es_3 of Lengjia Oilfield

辽河盆地冷家油田沙三段储层以盆底扇及扇三角洲沉积为主。盆底扇储集砂体主要发育于扇中及扇根水道 ,非均质程度高 ,非均质类型复杂 ,扇三角洲储集砂体主要为前缘亚相水下分流河道砂体及滩坝砂体 ,水下分流河道砂体非均质性类型为线性增加型。

Reservoirs in Es 3 of Lengjia Oilfield in Liaohe Basin are mainly composed of basin floor fan and fan delta deposits. The basin bottom reservoir sandbody is grown in the middle of the fan and in water channel of fan root, of which heterogeneity degree is high, the type of heterogeneity is complex. The fan delta reservoir sandbody is mainly composed of subsea distributary channel sandbody of frontal subfacies and beach sandbody, the heterogeneity type of the subsea distributary channel is a linear incremental one and the type of the beach sandbody is a linear reducing one.
