| 摘 要： | 研究区内西山窑组西3层沉积体系主体为扇三角洲沉积环境,亚相主要发育扇三角洲前缘亚相,微相主要发育水下分流河道、河口坝、河道侧翼与河道间微相.不同的沉积环境形成了不同的砂体规模和储层特征,由于其储层非均质性强弱不同,从而导致气井产能高低不同.研究发现分流河道微相位置产能较高;而分流河道侧翼及河道间湾位置产能较低.

| Abstract: | In Tu-ha basin Jurassic Xishanyao Group West three oil-bearing reservoir, the main fan delta depositional systems depositional environment, facies mainly developed fan delta front, microfacies mainly developed underwater distributary channel, mouth bar, between the river and river flank microfacies. Different dcpositional environments of sand formed different size and reservoir characteristics, reservoir heterogeneity due to their different strength, resulting in high and low gas wells. Distributary channel microfacies study found that the location of production capacity higher; while flanking and River distributary channel capacity between the position of the lower bay. |
