| 1 | 砂岩透镜体油气成藏机理初探显示文摘为了研究砂岩透镜体油气成藏机理,从生烃动力、生储油岩界面毛细管压力以及流体在生储油岩之间交换等方面进行了探讨,并通过物理模拟实验与典型实例解剖加以验证。认为无断层沟通的砂岩透镜体可以成藏,其成藏机理是:流体压差将泥岩中生成的油气驱向砂岩透镜体,毛细管压力差将泥岩与砂岩接触带的油气驱入砂岩透镜体,浮力使进入砂岩透镜体中的油气向其顶部聚集,砂岩透镜体中的水可以在毛细管压力差的作用下自然地由砂岩进入泥岩中。某些砂岩透镜体油气藏部分被油气充注而部分没有充注,不成藏的端元可能与驱烃动力不足、生烃高峰期滞后于成岩胶结期导致流体交换通道堵塞等有关。 | 赵文智 邹才能 谷志东 陶士振 | 2007 | 石油勘探与开发2007，34，3： | 51 |
| 2 | 应用定量颗粒荧光技术研究岩性油气藏的隐蔽输导通道显示文摘应用定量颗粒荧光技术对东营凹陷牛庄洼陷5口井101块沙三段致密储层、薄层粉砂岩进行了定量荧光QGF-E和QGF分析。分析表明,牛24、牛83、牛876、王550、牛872等5口井致密薄储层颗粒具有相对较高的荧光,显示这些较致密的粉砂岩为过去或现在的油气运移路径/运载层,表明致密砂岩、粉砂岩、薄层砂岩可作为烃类运移的通道。这类薄层隐蔽输导通道为深凹带牛庄洼陷深部沙四段上亚段烃源岩生成的油气进入无断层切割的沙三段中、下亚段的砂岩透镜体而成藏提供了重要的依据。该研究结果对于东营凹陷正在进行的隐蔽油气藏成藏机理的研究可能具有重要意义。 | 陈冬霞 庞雄奇 张俊 李明刚 | 2007 | 地质学报2007，81，2： | 26 |
| 3 | 砂岩透镜体成藏动力学过程模拟与含油气性定量预测显示文摘砂岩透镜体油藏作为我国东部油气储量增长的重点,其成藏动力学研究对于搞清这类特殊油气藏的成藏机理及定量评价和预测圈闭的含油气性具有重要意义.本文利用数值模拟结合地质分析的方法,在对成藏动力与成藏阻力进行系统分析的基础上,通过建立成藏动力地质模型和数学模型及成藏动力学特征方程,对砂岩透镜体成藏过程进行模拟.研究结果表明,成藏主动力包括砂泥岩毛细管压力差、烃浓度差引起的扩散力、烃生成产生的膨胀力,成藏阻力主要为砂体内毛细管阻力及岩石的粘滞力和吸附力;东营凹陷岩性油气藏能否成藏主要受泥岩排烃强度、储层孔隙度、渗透率、地层埋藏深度、泥(页岩)厚度与砂体厚度之比等因素的综合影响;岩性油气藏的形成具有阶段性,在晚成岩阶段,成藏动力大于成藏阻力,油气开始充注,岩性油气藏的形成存在门限深度.利用成藏动力学特征模拟,建立了成藏动力与含油性的定量关系,还可以很好地对平面上砂体的含油饱和度分布进行预测. | 陈冬霞 庞雄奇 邱桂强 张俊 高永进 | 2008 | 地球科学(中国地质大学学报)2008，33，1： | 8 |
| 4 | Hydrocarbon accumulation in network and its application in the continental rift basin显示文摘The concept of hydrocarbon accumulation in network was presented on basis of the overall analysis of the formation and evolution characteristics of the continental faulted basin and of the systemic re-search on the major controlling factors on the hydrocarbon accumulation. The hydrocarbon accumu-lation in network can be defined as hydrocarbon accumulation in a three-dimensional network system which is constituted by the hydrocarbon migration passages under multiple dynamics,following the hydrocarbon generation from source rocks. The research shows that the hydrocarbon accumulation in network is composed of four elements,i.e.,hydrocarbon source (source rock kitchen),hydrocarbon accumulation terminal (trap),network pathway connecting source and terminal (transporting system),and network potential driving hydrocarbon migration in the network pathway (migration dynamics). Compared with other networks,hydrocarbon accumulation in network has three basic characteristics: the irreversible geological process of material and information flow in the network; the loss of material and information in the flow process in the network; the multiple dynamics in the flow process. Interac-tion of all the elements in the geological process can be called hydrocarbon accumulation in network. There are three basic models for hydrocarbon accumulation in network,that is,hydrocarbon accumu-lation in the network source area,hydrocarbon accumulation in the network pathway,and hydrocarbon accumulation in the network terminal. The key in the application of the hydrocarbon accumulation models in network in practice is to confirm the major accumulation stage and the function range of the four elements controlling the hydrocarbon firstly,to predict the profitable accumulation region by su-perposition of the favorable areas confirmed by four elements consequently,and to evaluate the oil-bearing property of the trap as well as confirm drilling targets. This paper takes the Dongying De-pression in the Bohai Bay Basin as an application example. | PANG XiongQi1,2,CHEN DongXia1,ZHANG ShanWen3,HAO Fang1,LIU Zheng1,LIU KeYu3,SONG GuoQi4,WANG YongShi4,LUO XiaoRong5 & WU XiaoChun61 State Key Laboratory of Petroleum Resource and Prospecting,Chinese University of Petroleum,Beijing 102249,China 2 Basin and Reservoir Center,Chinese University of Petroleum,Beijing 102249,China 3 SINOPEC Shengli Oilfield,Dongying 257051,China 4 CSIRO Petroleum,P.

| 5 | 陆相断陷盆地油气网络成藏研究与应用显示文摘通过对陆相断陷盆地的形成演化特征的整体剖析和对油气成藏主控因素控油气作用的系统研究,提出了油气网络成藏的新概念.油气网络(路)系指油气自源岩中生成后,在各种动力作用下,顺输导体系向周边运移后的路径在时空中构成的三维立体系统.研究表明,油气网络由四大要素构成,它们分别是形成油气网络的物质来源——烃源灶、聚集油气的网端——圈闭、联接网源与网端的网路——输导体系、促使网路中油气运移的网势——运移动力.与其它形式的网络系统相比,油气网络有3个基本特征:一是油气网络中的物质流动和信息流动在地史过程中不可逆;二是油气网络中物质和信息的流动是以物质损耗和信息损耗为代价;三是存在多种不同类型的运烃运力.各要素在地史过程中同一时期内活跃并联合作用形成油气藏概称为网络成藏作用.网络成藏作用具有3种基本模式,即网源内成藏、网路上成藏、网末端成藏.油气勘探实践中应用网络成藏模式的关键是首先确定主成藏期及主成藏期四大要素的控油气作用范围;然后通过各网络要素叠合作用预测最有利成藏区带;最后通过要素关联机制评价圈闭含油气性并确定钻探目标.论文以渤海湾盆地东营凹陷列举了应用实例. | 庞雄奇 陈冬霞 张善文 郝芳 刘震 刘可禹 宋国奇 王永诗 罗晓容 | 2008 | 中国科学(D辑)2008，38，S1： | 3 |
