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.
Through the overall analysis of formation and evolution of terrestrial faulted basins and the systematic study on the role of oil and gas as the main controlling factors in the formation of oil and gas reservoirs, a new concept of hydrocarbon accumulation is proposed. Hydrocarbon network (road) In the formation of three-dimensional three-dimensional system in the space-time under the guidance of a variety of dynamic forces, along the transport path to the periphery of the transport system.Research shows that the oil and gas network consists of four elements, which are the formation of oil and gas network material Source-source stoves, net-trap for gathering oil and gas, network-guide system for connecting network source and network terminal, and driving the migration of oil and gas in the network. Compared to the network system, the oil and gas network has three basic characteristics: First, the material flow and information flow in the oil and gas network are irreversible in the history of the earth; second, the flow of material and information in the oil and gas network is based on the material loss and the information loss as Cost; Third, there are many different types of transport capacity of hydrocarbons.Every element in the history of the same period in the same period of active and joint formation of oil and gas reservoir is generally described as the role of network accumulation.Network accumulation has three basic The key to the application of network accumulation in oil and gas exploration is to determine the range of oil and gas controlled by the four major elements in the main hydrocarbon accumulation and main hydrocarbon accumulation periods. Then, the most favorable reservoir formation zone is predicted through the superimposition of various network elements. Finally, the hydrocarbon-bearing traps are evaluated and the drilling targets are determined through the element correlation mechanism.The application examples are given in Dongying Sag, Bohai Bay Basin.
