Regional correlation and study of the assemblage characteristics in the outer basins of the Daqing exploration area have great significance for revealing the characteristics of Meso-Cenozoic basin evolution in Northeast China and widening one's ideas of petroleum development. By using the lithological characteristics, fossil assemblages and isotopic data, Meso-Cenozoic strata in the outer basins of the Daqing exploration area are correlated and the microscopic characteristics of the stratigraphic...

Regional correlation and study of the assemblage characteristics in the outer basins of the Daqing exploration area have great significance for revealing the characteristics of Meso-Cenozoic basin evolution in Northeast China and widening one's ideas of petroleum development. By using the lithological characteristics, fossil assemblages and isotopic data, Meso-Cenozoic strata in the outer basins of the Daqing exploration area are correlated and the microscopic characteristics of the stratigraphic development are summarized. The authors propose four major exploration layers in the basins, i.e. the Mid-Upper Jurassic, Lower Cretaceous, Upper Cretaceous and Paleogene. This study provides a reliable basis for the further study of the sedimentation, tectonic evolution and petroleum geology in the outer basins of Daqing exploration area.

大庆外围盆地的区域对比与组合规律研究,对于揭示东北中、新生代盆地演化规律和拓展油气开发思路具有重要意义。利用岩性特征、古生物化石组合、同位素等资料,对大庆探区外围盆地中、新生代地层进行了对比,总结了地层发育的宏观规律,提出了中—上侏罗统、下白垩统、上白垩统和古近系四大勘探层系,为大庆探区外围盆地进一步的沉积、构造演化及石油地质研究提供了可靠的依据。

Based on Bouguer gravity and the aeromagnetic anomalies data of Daqing outer basins,we analyse the characters of geophysical fields of these basins.We apply the Harmonic series method on gravity data that eliminated gravity effect caused by deep construct to inverse the depth of gravity floor.We use the genetic algorithm method on magnetic data that eliminated magnetic effect caused by deep construct to inverse the depth of magnetic top of these basins.Then we make a future analyse to the characters...

Based on Bouguer gravity and the aeromagnetic anomalies data of Daqing outer basins,we analyse the characters of geophysical fields of these basins.We apply the Harmonic series method on gravity data that eliminated gravity effect caused by deep construct to inverse the depth of gravity floor.We use the genetic algorithm method on magnetic data that eliminated magnetic effect caused by deep construct to inverse the depth of magnetic top of these basins.Then we make a future analyse to the characters of these floors.The depth of gravity floor is between 0.2 km and 9.0 km,and the depth of magnetic top is between 1.8 km and 9.8 km.This shows the general status of basins.

根据收集到的大庆外围盆地的布格重力异常和航磁异常数据,对外围盆地中的8个盆地进行了地球物理场特征的分析.对各盆地的重力异常进行了由下地壳与上地幔的密度差引起的重力效应的剥离,对磁力异常进行了由居里面起伏引起的磁力效应的剥离.在此基础上应用调和级数法和遗传算法分别反演计算了这8个盆地的重力基底和磁性顶界面,并分析了其基底特征.各盆地重力基底在0.2~9.0 km之间变化,磁性顶界面在1.8~9.8 km之间变化,其特征反映了各盆地的基本现状.

Jiyang Depression,a typical terrestrial rifted basin experienced complicated tectonism and sedimentation,contains many well-developed subtle reservoirs.Research on the forming mechanism of the subtle reservoirs reveals three important theoretical understandings.First,steep and slow slope fault-steps and innerand outer-basin slope-breaks shaped during fault-dominated tectonism control the formation and distribution of reservoir rocks(also known as 'faulting-slope-controlled sandstone'),making the place an ideal area for exploration of subtle reservoirs.Secondly,different hydrocarbon conducting paths with the shape of meshwork-carpet,capi-tal letter 'T',ladder,and fractures,develop and operate inside the particular time-space tract in the basin,constituting a complex hydrocarbon transportation system(also known as 'compound transportation') and providing information for the evaluation of exploration direction of subtle reservoirs.Finally,the coupling relation between facies(receiving condition) and liquid potential(driving condition) determines reservoiring conditions and charateristics(also know as 'facies-potential-controlled reservoirs').These understandings constitute the kernel idea of subtle reservoir exploration and promote effectively the petroleum exploration in Jiyang depression during the Tenth Five-Year Plan.

作为典型的陆相断陷盆地,济阳坳陷经受了复杂的构造活动和沉积作用,隐蔽油气藏十分发育。通过隐蔽油气藏形成机制的研究,提出了三个重要的理论认识:其一,断裂主导的盆地构造活动形成的陡坡和缓坡断阶、盆内和凸缘坡折控制了储集岩的形成与分布,成为隐蔽圈闭目标区带优选的基础,亦即“断坡控砂”;其二,网毯式、“T”型、阶梯型、裂隙型等输导类型在盆地特定的时空域发育和产生作用,构成了复杂的油气输导网络体系,成为隐蔽油气藏勘探方向评价的条件,亦即“复式输导”;其三,相(接受条件)、势(动力条件)存在的耦合关系,决定了油气成藏的基本条件和不同特点,成为勘探目标评价的关键,亦即“相势控藏”。这三个观点构成了陆相断陷盆地隐蔽油气藏勘探思维的核心,有力地指导了“十五”期间济阳坳陷的隐蔽油气藏勘探。
