| 摘 要： | 吉木萨尔凹陷二叠系芦草沟组主要为湖泊和三角洲相沉积，岩石类型主要有泥岩、碳酸盐岩和细粒级碎屑岩。发育上、下2个致密油甜点体，下甜点体以细粒级碎屑岩沉积为主，三角洲前缘远砂坝和席状砂是储层甜点发育的主要微相类型；而上甜点体以碳酸盐岩类沉积为主，微相类型为滨浅湖滩坝。上、下甜点体厚度大，分布稳定，致密油勘探潜力巨大。

| Abstract: | In the Permian Lucaogou Formation in the Jimsar Sag, lake and delta facies strata deposited, and rocks mainly include mudstone, carbonate and fine-grained clastic rock. Two tight oil cookies developed. The lower cookies are mainly in fine-grained clastic rocks, and generate in the microfacies of delta front distal bar and sheet sand. The upper cookies are mainly in crabonate rocks, and generate in the microfacies of beach bar of shore shallow lake. The upper and lower cookies are thick and widespread, indicating giant potential for tight oil reservoir. |
