摘要： 滨里海盆地盐下层系具有丰富的油气资源,阿斯特拉罕气田、田吉兹油田等多个大型油气田的发现说明和它们处于相同构造带内的M 区块同样具有较大含油气潜力。但M 区块盐下层系埋深大,有利储集相带的预测成为该区块油气勘探的关键。在区域构造演化分析的基础上,通过与相邻油气田的对比、地震相分析等方法预测了M 区块盐下有利储集相带。结果表明,M 区块与阿斯特拉罕-阿克纠宾斯克隆起带上的次级隆起具有相似的构造演化特征,古地貌、基底差异沉降是有利储集相带分布的主要控制因素;有利储集相带为区块南北两侧上泥盆统-下石炭统的障壁礁和古隆起顶部石炭系滩坝相。

Abstract: Subsalt complex of the Precaspian basin is rich in oil and gas resources. The discovery of a number of large oil-gas fields like Astrakhan, Tengiz, etc., indicates that the Mezhdurechensky block which is in the same structural belt also has relatively high hydrocarbon potentials. However, the subsalt complex in Mezhdurechensky block is under a great burial depth, so the favorable reservoir facies belt prediction becomes the key for hydrocarbon exploration in this area. This paper analyzes the regional structural evolution, compares with adjacent oil and gas fields and conducts the seismic facies analysis in order to predict the favorable reservoir facies belt. The result shows that Mezhdurechensky block experienced a similar tectonic evolution history with the sub-uplifts on the Astrakhan- Aktyubinsk structural belt, and paleotopography and the differential basement subsidence are the main controlling factors for formation such a facies belt, and the favorable reservoir facies belt of subsalt complex in Mezhdurechensky block are barrier reef carbonate rocks of Upper Devonian and Lower Carboniferous on the north and south sides of the block and grainstones of the Carboniferous on banks and shoals on top of the paleouplifts.

Key words: Precaspian basin, Mezhdurechensky block, subsalt complex, seismic facies, reservoir
