| 摘 要： | 为了预测松辽盆地徐家围子断陷深层登娄库组二段致密砂岩的有利储层发育区,本文讨论了沉积相和成岩作用对致密砂岩储层物性的影响.结果表明:登二段最有利的沉积相是三角洲相和河道亚相,但进入晚成岩阶段A期以后,致密砂岩储层就难以产出工业气流;不同沉积相的砂体处于不同的成岩阶段,形成了登二段致密砂岩三种不同类型的储层(Ⅱ、Ⅲ、Ⅳ类).应用成岩作用数值模拟技术,结合沉积相的研究成果,本文预测了登二段致密砂岩各种类型储层的平面分布特征.目前已发现的工业气流井主要位于Ⅱ、Ⅲ类储层分布的范围内,这些砂岩就是致密砂岩中有利储层的发育区. |

| Abstract: | To predict better reservoirs of tight sandstones in the Member 2 of the Denglouku Formation(K1d2),Xujiaweizi rift depression,Songliao basin,the effects of sedimentary facies and the diagenesis on reservoir porosity were discussed.The results showed that the favorable sedimentary facies of K1d2 are delta facies and river channel sub facies;and that little commercial gas flow was produced from the tight sandstone reservoirs in the late diagenetic stage after the period A.The sandstones in different sedimentary facies and different diagenetic stages had formed three kinds of tight sandstone reservoirs,types Ⅱ,Ⅲ,and Ⅳ.The tight sandstone reservoir types of the Member 2 of the Denglouku formation were predicted laterally by the diagenetic numerical model combining with the sedimentary facies.Current commercial gas flow wells are mainly located in the type Ⅱ and type Ⅲ,where the most favorable reservoirs are located. |
