备注

松辽盆地油页岩资源储量巨大且分布广泛,主要赋存于上白垩统青山口组一段和嫩江组一段、二段,含油率中等,一般为4.7%~5.1%左右。从松辽盆地油页岩地质特征及时空分布出发,选取主采层厚度和矿体埋深参数,建立油页岩段和盆地的优选标准,建立松辽盆地勘探开发有利区优选体系,将其划分为最有利、有利、较有利和一般有利4个级别的油页岩勘探开发区。其中,南起伏龙泉-农安,经增盛,北至肇源的地区为下一步勘探开发的靶区。

The oil shale in Songliao Basin is widely distributed with huge reserves. And the deposits mainly occurred in 1st member of the Upper Cretaceous Qingshankou Formation and the 1st, 2nd members of the Nenjiang Formation with the middle oil content ranging from 4.7%~5.1%. According to the geological characteristics and space-time distribution regularities of the oil shale, the thinkness and the depth of the main strata were selected as the evaluation parameters and the optimization system of favorable exploration and development was built. Based on the optimization system, four types of regions, namely the most favorable area, the favorable area, the sub-favorable area and the generally area were divided. And the evaluation reults show that the region from Fu longquan-Nong An in south via Zengsheng to Zhaoyuan in north is the favorable area for next step exploration and development work.
